The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1, the present invention discloses a pedal-type welding mechanism 10 for controlling gas output, which comprises: the workbench 20, the welding gun 30 and a foot-operated control gas output device 40.

As shown in FIG. 1, the welding torch 30 is disposed on the top of the worktable 20, the foot-operated controlled gas output device 40 is disposed at the bottom of the worktable 20, and the welding torch 30 and the foot-operated controlled gas output device 40 are connected by a gas transmission pipeline 50.

When a quality inspection department detects that the current product has quality problems and needs to be repaired, the loosened part is secondarily fixed in a welding mode, and the part is locally melted by utilizing high temperature generated during gas combustion, so that the aim of stably welding is fulfilled. Workers can place products to be welded on the table top of the workbench 20, and step on the foot-operated gas output device 40 to enable gas in the foot-operated gas output device 40 to reach the welding gun 30 through the gas conveying pipeline 50, the gas at the welding gun 30 is ignited, high temperature is generated in the combustion process of the gas, the welding gun 30 is aligned to the welding position, and then local parts are melted, so that welding is achieved. In the process, workers hold a product to be welded with one hand and hold the welding gun 30 with the other hand, and simultaneously pedal the pedal type control gas output device 40 to output gas, and all parts of the body are cooperatively matched, so that the aim of efficient work is fulfilled.

The structure of the foot-operated control gas output device 40 and the connection relationship of the respective components will be described below:

specifically, as shown in fig. 2, the foot-operated control gas output device 40 includes: fixed base 100, gas cylinder 200, running-board 300.

The fixing base 100 is provided with a gas output control chamber 110 (as shown in fig. 3), the gas cylinder 200 is mounted on the fixing base 100, and the chamber of the gas cylinder 200 is communicated with the gas output control chamber 110. The body of the gas cylinder 200 is filled with combustion-supporting gas, which comes out from the mouth of the cylinder and reaches the cavity of the gas output control chamber 110.

As shown in fig. 4, the gas output control chamber 110 has a gas output port 111, the gas output port 111 is provided with an open/close valve 120 and a valve return elastic member 130, and the valve return elastic member 130 is used for providing an elastic return force for the open/close valve 120, so that the open/close valve 120 maintains a tendency of returning toward the gas output port 111. In this embodiment, the valve return elastic member 130 is a spring structure. The open/close valve 120 is used to control the gas in the gas output control chamber 110, when the open/close valve 120 is pressed on the gas output port 111, the gas in the gas output control chamber 110 cannot be output, and when the open/close valve 120 is separated from the gas output port 111, the gas in the gas output control chamber 110 can be output through the gas output port 111.

As shown in fig. 3, the pedal 300 is rotatably disposed on the fixed base 100, the pedal 300 is provided with an arc-shaped guide groove 310, the fixed base 100 is provided with the guide post 140, and the guide post 140 is accommodated in the arc-shaped guide groove 310. The arc-shaped guide slots 310 cooperate with the guide posts 140 such that the footrest 300 can be rotated in a stable, non-yawing manner with a defined path.

Further, the pedal-controlled gas output device 40 further includes a gas output opening/closing assembly 400 (shown in fig. 2). As shown in fig. 3, the gas output opening/closing assembly 400 includes a telescopic lever 410 and a telescopic elastic member 420. The body of the telescopic control lever 410 is inserted into the gas output control chamber 110, one end of the telescopic control lever 410 is hinged to the pedal 300, and the other end of the telescopic control lever 410 is pressed or separated from the on-off valve 120. The telescopic elastic member 420 serves to provide elastic restoring force to the telescopic control lever 410 so that the telescopic control lever 410 maintains a tendency to be separated from the open/close valve 120. In this embodiment, the elastic member 420 has a spring structure.

Next, the fitting relationship between the foot pedal 300 and the gas output opening/closing unit 400 will be described:

a worker steps on the foot pedal 300 with one foot to apply an external force to the foot pedal 300, so that the foot pedal 300 rotates around the fixed base 100;

because one end of the telescopic control rod 410 is hinged to the pedal 300, the pedal 300 can drive the telescopic control rod 410 to move in the gas output control cavity 110, and thus, the other end of the telescopic control rod 410 can approach the opening/closing valve 120, when the telescopic control rod 410 is pressed on the opening/closing valve 120, the opening/closing valve 120 can be connected with the gas output port 111, so that the gas output port 111 is in an open state, and thus, the gas in the gas output control cavity 110 can be output through the gas output port 111;

since one end of the gas delivery pipe 50 is connected to the gas outlet 111, the gas output from the gas outlet 111 passes through the gas delivery pipe 50 and reaches the welding torch 30.

In the process of welding products, special attention needs to be paid to control the welding temperature, and the welding temperature is different from the welding temperature for different parts of the products. In order to realize the control of the "duration and degree of heating", the gas output of the welding gun 30 is mainly controlled, the "duration and degree of heating" is strong, the gas output is small, and the "duration and degree of heating" is naturally moderate.

In order to solve the technical problem, as shown in fig. 4, the opening/closing valve 120 has a spherical structure, the gas outlet 111 has a truncated cone opening structure, and the opening/closing valve 120 of the spherical structure is pressed against or separated from the gas outlet 111 of the truncated cone opening structure. Therefore, since the gas outlet 111 is a truncated cone opening structure, when the open-close valve 120 is far away from the gas outlet 111, the space gap between the open-close valve 120 and the gas outlet 111 is larger, and thus the gas output amount of the gas is larger; when the open/close valve 120 is close to the gas outlet 111, the space gap between the open/close valve 120 and the gas outlet 111 is smaller, so that the gas output amount is smaller.

Further, as shown in fig. 3, the telescopic control rod 410 has a guiding rod 411 and a triggering rod 412, the radial dimension of the guiding rod 411 is greater than the radial dimension of the triggering rod 412, the sidewall of the guiding rod 411 is attached to the wall of the gas output control chamber 110, and a gap is formed between the sidewall of the triggering rod 412 and the wall of the gas output control chamber 110. A gap is formed between the sidewall of the trigger bar 412 and the wall of the gas output control chamber 110, so that gas can pass through the gas output control chamber 110 well, and the trigger bar 412 does not obstruct the gas transportation. The side wall of the guiding rod 411 is attached to the wall of the gas output control chamber 110, so that the whole telescopic control rod 410 can move in the gas output control chamber 110 more stably.

In the present embodiment, the fixing base 100 is provided with a positioning plate 150 (as shown in fig. 3), and the plate surface of the pedal 300 is pressed against or separated from the plate surface of the positioning plate 150. The positioning plate 150 is used to provide support for the pedal 300, and when the pedal 300 rotates to the limit position, the positioning plate 150 will position the pedal 300 to prevent the pedal 300 from rotating excessively.

In the present embodiment, the gas output control chamber 110 has a gas input port 112 (as shown in fig. 3), and the mouth of the gas cylinder 200 is screwed onto the gas input port 112.

It should be noted that, in the present invention, the pedal 300 is further provided with a pedal return block 301 (as shown in fig. 3), and the pedal return block 301 is abutted against or separated from the rod body of the telescopic control rod 410. Under the elastic restoring force of the elastic member 420, the elastic member 420 causes the expansion control lever 410 to move reversely and reset, and the expansion control lever 410 drives the pedal 300 to rotate reversely and reset. In the process of reversely moving and resetting the telescopic control rod 410 and reversely rotating and resetting the pedal plate 300, the pedal reset blocking block 301 on the pedal plate 300 is pressed on the rod body of the telescopic control rod 410, so that the pedal plate 300 cannot continuously rotate any more under the limitation of the telescopic control rod 410 through the pedal reset blocking block 301, and the pedal plate 300 can be stably positioned.

The welding mechanism 10 with pedal type gas output control of the invention is provided with a workbench 20, a welding gun 30 and a pedal type gas output control device 40. The welding gun 30 is arranged on the table top of the workbench 20, the foot-operated controlled gas output device 40 is arranged at the bottom of the workbench 20, and the welding gun 30 and the foot-operated controlled gas output device 40 are connected through a gas conveying pipeline 50. When a quality inspection department detects that the current product has quality problems and needs to be repaired, the loosened part is secondarily fixed in a welding mode, and the part is locally melted by utilizing high temperature generated during gas combustion, so that the aim of stably welding is fulfilled. Workers can place products to be welded on the table top of the workbench 20, and step on the foot-operated gas output device 40 to enable gas in the foot-operated gas output device 40 to reach the welding gun 30 through the gas conveying pipeline 50, the gas at the welding gun 30 is ignited, high temperature is generated in the combustion process of the gas, the welding gun 30 is aligned to the welding position, and then local parts are melted, so that welding is achieved. In the process, workers hold a product to be welded with one hand and hold the welding gun 30 with the other hand, and simultaneously pedal the pedal type control gas output device 40 to output gas, and all parts of the body are cooperatively matched, so that the aim of efficient work is fulfilled.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
