Referring to fig. 1, the key blank 40 processing clamp provided in the embodiment of the present invention includes a base 10, a fixing shaft 20, a clamp seat 30 and an adjusting assembly 50, wherein the fixing shaft 20 is disposed on the base 10; the clamp seat 30 is rotatably sleeved on the fixed shaft 20 and is provided with a plurality of clamping grooves 301 for clamping the key blanks 40 along the circumferential direction; the adjustment assembly 50 is coupled to the clamp base 30 for adjusting the size of the clamping slot 301 to clamp or release the key blank 40.

The key blank 40 can be clamped and fixed in the clamping groove 301 through the clamp seat 30, and the clamp seat 30 can move along the axial direction of the fixing shaft 20 when being driven, so that the clamp seat 30 moves relatively to separate or move relatively to approach, and further the clamping groove 301 can place the key blank 40 when being opened, and clamp and fix the key blank 40 when the clamping groove 301 is closed.

According to the key blank 40 processing clamp provided by the invention, the clamping groove 301 required to be used can be rotated to the processing position by rotating the clamp seat 30, then the size of the clamping groove 301 is adjusted to be matched with the key blank 40 by the adjusting assembly 50, and the key blank 40 can be placed into the clamping groove 301 to be clamped and fixed for processing, so that different types of key blanks 40 can be clamped and fixed by the clamp seat 30, the operation process is simple and convenient, the processing of the key blank 40 is more convenient, the clamp does not need to be replaced, and the processing time is saved.

Referring to fig. 2, the clamp holder 30 includes a first clamping block 31, a second clamping block 32, and an elastic member 80 elastically abutted between the first clamping block 31 and the second clamping block 32, wherein the first clamping block 31 is rotatably disposed on the fixed shaft 20; the second clamping block 32 is butted and connected with the first clamping block 31 to form a clamping groove 301; the adjusting assembly 50 is connected to the second clamping block 32 for driving the second clamping block 32 to move along the axial direction of the fixed shaft 20 relative to the first clamping block 31 to adjust the size of the clamping groove 301. Specifically, when the adjusting assembly 50 releases the second clamping block 32, under the elastic force of the elastic member 80, the first clamping block 31 and the second clamping block 32 are relatively far away from each other, and the width of the clamping groove 301 is increased, so that the key blank 40 can be conveniently placed in the key blank. After the key blank is placed into the clamping groove 301, the adjusting assembly 50 presses the second clamping block 32, the elastic member 80 is compressed, the first clamping block 31 and the second clamping block 32 are relatively close to each other, the width of the clamping groove 301 is reduced, and the key blank 40 is clamped.

Referring to fig. 3, the circumferential surface of the fixed shaft 20 has a plurality of positioning holes 201 arranged at intervals, the first clamping block 31 has a plurality of elastic positioning members 60 arranged at intervals along the circumferential direction, and the elastic positioning members 60 extend along the radial direction of the first clamping block 31 and abut against the fixed shaft 20; the elastic positioning member 60 can be rotated with the first clamping block 31 to be engaged with the positioning hole 201, so that the rotation of the first clamping block 31 is limited by the elastic positioning member 60.

In this embodiment, the elastic positioning element 60 may be a ball screw, the fixed shaft 20 may be a cylindrical shaft, and the number of the positioning holes 201 provided on the circumferential surface of the fixed shaft 20 may be plural, in this embodiment, the number of the clamping grooves 301 is 5, the number of the positioning holes 201 is also 5, and each clamping groove 301 corresponds to one elastic positioning element 60. When the elastic positioning element 60 abuts against the positioning hole 201, the fixture seat 30 can be limited by the elastic positioning element 60 on the fixing shaft 20 to be incapable of rotating, when the fixture seat 30 is rotated by applying force, the elastic positioning element 60 rotates along with the fixture seat 30 to be separated from the positioning hole 201, when the clamping groove 301 to be used is rotated to a processing position, the elastic positioning element 60 is correspondingly switched to other positioning holes 201, and further when the fixture seat 30 stops rotating, the elastic positioning element 60 can elastically abut against the inside of the positioning hole 201 to further limit the fixture seat 30 to rotate, so that the fixture seat 30 is more stable and reliable in processing, and the key blank 40 is more simply and conveniently clamped; it can be understood that the elastic positioning element 60 may be disposed on the first clamping block 31 to limit the clamp seat 30, or disposed on the second clamping block 32 to limit the clamp seat 30, and those skilled in the art may set the elastic positioning element according to actual requirements to adapt to different usage scenarios.

Specifically, the base 10 is provided with a first supporting plate 11 and a second supporting plate 12 which are oppositely arranged, the fixing shaft 20 is fixedly arranged on the first supporting plate 11, and the second supporting plate 12 is detachably connected with the base 10. Wherein, the fixed axle 20 is fixed on the first backup pad 11 and can't rotate for the anchor clamps seat 30 is rotatable relative to the first backup pad 11, and the second backup pad 12 is set to be detachable, then can be with base 10 fixed mounting when needing to use, can dismantle when wasing to maintain or change anchor clamps seat 30.

Referring to fig. 2 and 3, the adjusting assembly 50 includes a screw 51 and a knob 52, the screw 51 is in threaded connection with the second support plate 12, and the screw 51 penetrates through the second support plate 12. One end of the screw 51 close to the second clamping block 32 is provided with a thrust part 511, and the knob 52 is fixed at one end of the screw 51 far away from the thrust part 511. Since the screw 51 is in threaded connection with the second support plate 12, when the knob 52 is rotated, the screw 51 moves linearly, and therefore the screw 51 drives the pushing portion 511 to press or release the second clamping block 32. When the screw 51 presses the second clamping block 32, the elastic member 80 simultaneously generates pressing force on the first clamping block 31, so that the first clamping block 31 is pressed against the first support plate 11 for positioning, and under the condition that the first clamping block 31 is combined to form positioning through the cooperation of the elastic positioning member 60 and the positioning hole 201, the key blank processing clamp has double repositioning, so that the stability of the key blank 40 in the processing process is ensured.

Specifically, the adjusting assembly 50 further includes a thrust bearing 70 sleeved on the screw 51, and the thrust bearing 70 is disposed between the thrust portion 511 and the second clamping block 32.

Specifically, the second clamping block 32 is provided with a concave portion 322, and the concave portion 322 matches with the end surface of the first clamping block 31 close to the second clamping block 32 to form a involution relationship, so that when the adjusting assembly 50 releases the second clamping block 32 and rotates the first clamping block 31, the second clamping block 32 can be synchronously driven to rotate, and thus the switching of the clamping grooves 301 at different positions is completed.

Example two

Referring to fig. 5 and 6, the difference between the second embodiment and the first embodiment is that: only the first support plate 11 is disposed on the base 10, and the installation manner of the adjustment assembly 50 is different. Specifically, the adjustment assembly 50 includes an adjustment rod 53, a knob 52, and the knob 52 is fixed to the adjustment rod 53. The adjusting lever 53 is provided with a pressing portion 531, and a transmission portion 532 located at the front end of the pressing portion 531. The second clamping block 32 is sleeved on the transmission part 532 of the adjusting rod 53, the transmission part 532 is in threaded transmission connection with the fixing shaft 20, the knob 52 is rotated, the adjusting rod 53 moves along the axial direction of the fixing shaft 20, and the pressing part 531 presses or releases the second clamping block 32, so that the size of the clamping groove 301 is adjusted. In the present embodiment, the stationary shaft 20 is provided with an internal thread and the transmitting portion 532 is provided with an external thread. In order to prevent the knob 52 from being completely separated from the fixing shaft 20 during the rotation process, in this embodiment, a scale mark (not shown) is disposed on the end surface of the first clamping block 31 close to the second clamping block 32, and when the second clamping block 32 is far away from the first clamping block 31 to the scale mark, the knob 52 stops rotating.

Referring to fig. 5, the adjusting assembly 50 further includes a thrust bearing 70 sleeved on the adjusting rod 53, and the thrust bearing 70 is disposed between the pressing portion 531 and the second clamping block 32.

It can be understood that the elastic member 80 forms an elastic force between the first clamping block 31 and the second clamping block 32, the screw 51 forms a support between the second clamping block 32 and the support, and the distance between the clamping grooves 301 can be adjusted by rotating the screw 51, so as to clamp the key blank 40; and, when the adjusting screw 51 is rotated, the elastic force of the elastic member 80 may make the stability between the first clamping block 31 and the second clamping block 32 better.

Referring to fig. 3 and 6, the first clamping block 31 and the second clamping block 32 are provided with a guide 90, and the guide 90 extends in the axial direction of the fixed shaft 20 to form a guide between the first clamping block 31 and the second clamping block 32. When the second clamping block 32 is driven by the screw 51 to move along the axial direction, the guide 90 can form a guide between the first clamping block 31 and the second clamping block 32, so that the positions of the second clamping block 32 and the first clamping block 31 are not easy to shift, and the precision of the key blank 40 is higher in the process of machining and cutting the key blank 40.

The invention also provides processing equipment, which comprises the key blank processing clamp. The processing equipment is provided with the key blank processing clamp, so that the processing equipment can clamp and fix different key blanks 40 through the key blank processing clamp and perform cutting processing, the technical effects and the technical scheme are consistent with the above, and the details are omitted.
