[0009] Compared with the prior art, the technical effect of the present invention is that the present invention is provided with a compression spring, which facilitates the compression of the workpiece and provides convenience for standard operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the prior art.

[0011] Figure 2 It is a schematic diagram of the present utility model.

[0012] Figure 3 It is a top view schematic diagram of the crossbar.

[0013] Specific ways to try

[0014] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments thereof.

[0015] like Figure 2 A driving gear marking fixture includes a base 10, which is provided with a vertical cavity 11. A pad 40 is provided above the vertical cavity 11. A sliding column 41 is fixed on the lower surface of the pad 40. The sliding column 41 is inserted into the vertical cavity 11 and can slide along it. A compression spring 12 is provided between the lower bottom surface of the sliding column 41 and the bottom surface of the vertical cavity 11.

[0016] A vertical rod 20 is fixed on each edge of the base 10 , and its lower end is fixed on the base 10 . A cross rod 30 is provided above the pad 40 , and its two ends are distributed and fixed on the upper section of a vertical rod 20 .

[0017] The portion of the crossbar 30 located directly above the backing plate 40 is a pressing portion 32 , which is used to press the small end surface 91 of the driving gear.

[0018] like Figure 2-3 The heights of different models of driving gears are different, so it is necessary to adjust the distance from the cross bar 30 to the bottom surface. To this end, the upper section of the vertical rod 20 is a threaded section 21, and the threaded section 21 is threadedly matched with the lower nut 22 and the upper nut 23. The end of the cross bar 30 is provided with a through hole 31, which is sleeved on the threaded section 21, and the end of the cross bar 30 is clamped between the lower nut 22 and the upper nut 23.

[0019] In order to facilitate clamping, the pressing portion 32 is arc-shaped, which increases the contact area with the small head end surface 91 and makes the clamping more stable.

[0020] Its working principle is:

[0021] S1. Preparation: First estimate the distance between the cross bar 30 and the bottom surface. If it is not appropriate, adjust it. When adjusting: screw on the upper nut 23, remove it, then remove the cross bar 30, screw down the lower nut 22 to the appropriate position, then place the cross bar 30, and finally screw on the nut 23 to hold the cross bar 30 together with the lower nut 22.

[0022] S2. Put the workpiece on: tilt the large end of the workpiece and place it on the upper surface of the pad 40, with the small end side surface close to the inner arc surface of the clamping part 32. Hold the workpiece with your hand and press it down hard, so that the pad 40 and the sliding column 41 move downward synchronously. At the same time, the compression spring 12 is compressed. When the workpiece can be placed vertically under the clamping part 32, release the workpiece, and the compression spring 12 resets, driving the pad 40, the sliding column 41, and the workpiece to move upward synchronously until the small end surface 91 contacts the lower surface of the clamping part 32. At this time, the workpiece is fixed.

[0023] S3, marking. This is a prior art and will not be described in detail.

[0024] S4. Remove the workpiece: Hold the workpiece with your hand and press it down hard, so that the pad 40 and the sliding column 41 move downward synchronously. At the same time, the compression spring 12 is compressed. At this time, the small end of the workpiece is tilted. When the workpiece does not contact the lower surface of the clamping part 32, the workpiece is not constrained. At this time, the workpiece can be taken away, and then the compression spring 12 is reset, driving the pad 40 and the sliding column 41 to reset.

[0025] Features of this application:

[0026] S1. The utility model does not rely on mechanical equipment and is easy to operate.

[0027] S2. Adapt to different types of workpieces.

[0028] For other contents, please refer to the prior art.

[0029] The above description is only the preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
