[0023] Combine the following Figure 1-Figure 3 The utility model is described in detail.

[0024] Example

[0025] A clamping tool for batch parts processing includes a base 1, a positioning groove 3 for placing a part 2 is arranged on the upper surface of the base 1, a clamping mechanism for clamping the part 2 is arranged on the base 1, a mounting groove 16 intersecting with the positioning groove 3 is opened on the upper surface of the base 1, a ejection cam 9 is rotatably connected in the mounting groove 16, and the ejection cam 9 is connected to a handle 11 located on the outside of the base 1 through a connecting rod.

[0026] The connecting rod can be connected to the end surface (such as the axis center) of the ejecting cam 9 or to the circumferential surface of the ejecting cam 9, so as to drive the ejecting cam 9 to rotate.

[0027] The clamping mechanism presses the part 2 in the positioning groove 3, and then processes the part 2. After the processing is completed, the clamping limit of the clamping mechanism is released, and then the ejection cam 9 is rotated by the handle 11. The highest point of the ejection cam 9 will protrude from the bottom of the positioning groove 3, thereby ejecting all the parts 2 out of the positioning groove 3. There are two groups of ejection cams 9 to facilitate better lifting of the parts 2; there are several positioning grooves 3. When processing the part 2, the present application needs to drill holes at both ends of the part 2, so it is also necessary to vertically open corresponding through holes in the positioning groove 3 to facilitate the downward movement of the drill bit and the discharge of impurities.

[0028] The base 1 is provided with an active cavity 17 located below the mounting groove 16, and a push rod 13 is vertically and movably provided in the active cavity 17. An abutment groove 12 is provided on one side of the ejection cam 9, and the ejection rod 13 is movably extended into the mounting groove 16 and abuts against the abutment groove 12. An elastic member 15 abutting against the bottom of the ejection rod 13 is provided in the active cavity 17. After the ejection cam 9 is rotated to eject the part 2, the abutment groove 12 abuts against the ejection rod 13 and causes the ejection rod 13 to retract downward into the active cavity 17, and the elastic member 15 is compressed at the same time. When the handle 11 is released, the elastic member 15 drives the ejection rod 13 to push the ejection cam 9 back to the initial position, thereby facilitating the subsequent placement of the part 2. The elastic member 15 can be set as a spring.

[0029] The movable cavity 17 is connected to the bottom of the base 1, and the fixing seat 14 is threadedly connected in the movable cavity 17. A detachable fixing seat 14 is provided to facilitate the installation of the elastic member 15 and the top rod 13. The bottom of the fixing seat 14 is provided with a groove, such as a slot and a cross slot, which is convenient for tools to rotate the fixing seat 14.

[0030] The clamping mechanism includes a clamping block 8 arranged on the base 1 and located on both sides of the ejection cam 9. The side wall of the clamping block 8 is provided with a concave step 18, and a pressure strip 10 is movably engaged in the concave step 18. The clamping block 8 is vertically provided with a pin 4 that penetrates the clamping block 8 and the pressure strip 10. Two pressure strips 10 are arranged along the length direction of the ejection cam 9, and are located on both sides of the clamping block 8 to clamp the two ends of the part 2. After all the parts 2 are placed in the positioning groove 3, the pressure strip 10 presses all the parts 2 in the positioning groove 3, and the pressure strip 10 is clamped in the concave step 18, and the pressure strip 10 is fixed by the pin 4.

[0031] The pin 4 on one of the clamping blocks 8 is a fixed pin, and the pin 4 on the other clamping block 8 is a movable pin. The edges of the bead 10 are chamfered. When it is necessary to release the clamping effect of the bead 10 on all parts 2, all the pins 4 can be removed and then the bead 10 can be taken out, but this operation is more troublesome; therefore, the removal operation of the bead 10 is designed to be opened by rotation, and the fixed pin at one end of the bead 10 does not need to be removed, and only the movable pin needs to be removed and the bead 10 can be rotated, which is more convenient to operate; and the edges of the bead 10 are chamfered to prevent the bead 10 from abutting against the side of the part 2 and the edge of the concave step 18 during the rotation process, which affects the rapid rotation of the bead 10.

[0032] A mounting hole 7 is vertically provided on the pressing block 8, and a screw rod 5 threadedly connected to the base 1 is provided in the mounting hole 7. The pressing block 8 is detachably connected to the base 1 through the screw rod 5, which is convenient for assembly operation.

[0033] A clearance groove 6 is provided in the positioning groove 3. The clearance groove 6 can facilitate the part 2 to be taken out after being ejected from the positioning groove 3.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
