Technical Field

The invention relates to the technical field of auxiliary tools of grinding machines, in particular to an automatic counterweight device for mounting parts of a centerless grinding machine.

Background

The sliding fork part 1 is hollow tubular because the grinding end, and fork portion weight ratio grinds the weight of processing end and is heavy, and the part is directly put on the layer board 4 of centerless grinder during grinding processing, because the focus is close to fork portion, can make the part grind the processing end perk and make the part fall layer board 4 down, causes the centerless to grind processing and can't go on smoothly. As shown in fig. 1, in the present production, a clump weight 2 needs to be inserted into an inner hole of a sliding fork part 1 to ensure that the sliding fork is placed on a supporting plate 4 of a centerless grinding machine without being placed stably. The defects are as follows: 1. before grinding, one end of the sliding fork is required to be provided with a balancing weight 2, so that parts are stably placed on the supporting plate 1, the action of placing the balancing weight 2 is increased, and the production efficiency is influenced; meanwhile, the weight of the part and the weight of the balancing weight 2 are increased, so that the labor intensity of operators is improved; 2. the excircle grinding machining length of the sliding fork is controlled by matching the end face of the balancing weight 2 with the axial positioning block 3, the length fluctuation error of the positioning block is increased, different balancing weights are used for simultaneous production, and the grinding machining length fluctuates.

Disclosure of Invention

The invention aims to overcome the defects in the background technology and provide an automatic counterweight device for mounting parts of a centerless grinding machine, so that the parts of a sliding fork can be stably placed on a supporting plate under the condition of not increasing a counterweight, the matching precision is high, and the grinding length is stable.

The technical scheme adopted by the invention is as follows:

the utility model provides an automatic counter weight device of centerless grinder part installation, which comprises a supporting plate, the mount pad, the axial positioning support, balancing weight and adjusting screw, layer board horizontal installation is in the side of guide pulley, the top surface at the layer board is fixed through the mount pad to the axial positioning support, the front end system of axial positioning support has vertical section and horizontal segment, the leading flank of vertical section is fixed with the axial and leans on the piece, the horizontal segment is fixed at the top of vertical section and is overhanging forward, the vertical top surface at the horizontal segment of adjusting screw, the through-hole has been seted up on the horizontal segment, the balancing weight is located the top of horizontal segment, the bottom surface pressure of balancing weight is on adjusting screw, the central point of balancing weight bottom surface puts the system and has the locating lever, the locating lever is supported by the outer wall at the slip fork part after passing the through-hole down vertically.

Preferably, the lower end of the positioning rod is provided with a spherical surface, and the spherical surface is abutted against the outer wall of the sliding fork part.

Preferably, the axial abutment blocks are arranged in a vertical direction.

Preferably, the axial abutting block is made of hard alloy.

The invention has the beneficial effects that: by adding the sliding fork part counterweight device on the centerless grinding equipment, the action of firstly installing a counterweight block on each part before machining is cancelled, and the production efficiency is improved; the weight of the balancing weight does not need to be increased when the parts are taken and placed every time, and the labor intensity of operators is reduced; the part is directly axially positioned with the positioning block, so that the stability of the grinding length is improved.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples, but the present invention is not limited to the following examples, so that the objects, solutions and advantages of the present invention can be more clearly understood by those skilled in the art.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified and limited, specific meanings of the general terms in the present invention may be specifically understood by those skilled in the art.

As shown in fig. 2, the automatic counterweight device for mounting parts of centerless grinding machine provided by the invention comprises a supporting plate 4, a mounting seat 5, an axial positioning bracket 6, a counterweight 2 and an adjusting screw 7. The supporting plate 4 is horizontally arranged on the side surface of the guide wheel 8, the axial positioning support 6 is fixed on the top surface of the supporting plate 4 through the mounting seat 5, and the front end of the axial positioning support 6 is provided with a vertical section 6.1 and a horizontal section 6.2. The front side surface of the vertical section 6.1 is fixed with an axial abutting block 9, the axial abutting block 9 is arranged along the vertical direction, and the axial abutting block is made of conventional hard alloy. Horizontal segment 6.2 is fixed at the top of vertical section 6.1 and is overhanging forward, and adjusting screw 7 is vertical to be installed at the top surface of horizontal segment 6.2, has seted up the through-hole on horizontal segment 6.2, and balancing weight 2 is located horizontal segment 6.2's top, and the bottom surface of balancing weight 2 is pressed on adjusting screw 7, and the central point of 2 bottom surfaces of balancing weight puts the system and has locating lever 2.1, and locating lever 2.1 supports after passing the through-hole vertically downwards and leans on at the outer wall of slip fork part 1. The lower end of the locating rod 2.1 is provided with a spherical surface 2.2, and the spherical surface 2.2 is abutted against the outer wall of the sliding fork part 2.2.

The working principle of the invention is as follows: the locating lever 2.1 of 2 bottoms of balancing weights penetrates in the through-hole, make cooperation piece 2 can only reciprocate, adjust the position that reciprocates of balancing weights 2 with adjusting screw 7, make the excircle of the slip fork part 1 of treating processing just in time can put into balancing weights 2 and guide pulley 8 and the space that 4 three points of layer board constitute, the terminal surface of the 1 rear end of slip fork part supports and leans on piece 9 by the axial, ensure grinding length's stability and axial positioning support 6's wearability. The axial positioning bracket 6 is fixed on the supporting plate 4 through the mounting seat 5. When the sliding fork part 1 is processed, the balancing weight 2 is used for balancing the part and placing the part on the supporting plate, so that the normal processing of the part centerless grinding is ensured.

Before grinding each time, a balancing weight does not need to be installed at one end of a sliding fork part, and a lighter excircle processing end of the sliding fork is tightly pressed through the balancing weight capable of sliding up and down, so that the part is stably placed on the supporting plate, the action of placing the balancing weight is reduced, and the production efficiency is improved; meanwhile, the weight of the balancing weight is not added to the part, and the labor intensity of operators is reduced. The excircle of slip yoke part grinds processing length, and the terminal surface through the slip yoke directly supports to lean on the axial positioning support 6 to lean on the piece 9 to control, has eliminated the length fluctuation error that originally need put into axial positioning piece 3 and cause, grinds the face length stability.

The above description is only a preferred embodiment of the present invention, and various modifications and changes may be made by those skilled in the art.
