[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical method of the present invention, but the present invention is not limited to these embodiments.

[0034] like Figure 1-5 As shown, the utility model provides a product clamping structure of a fixture, comprising:

[0035] A molding die set 100 for placing a product 110 thereon;

[0036] The product clamping module 200 is inserted into the molding die 100 and is used to clamp or release the product 110. The product clamping module 200 includes a fixed seat 210, a clamping arm 220, and a driving rod 230. The fixed seat 210 is connected to the molding die 100, and the clamping arm 220 is rotatably connected to the fixed seat 210 and the clamping arm 220 is also linked to the driving rod 230. The linear motion of the driving rod 230 drives the clamping arm 220 to rotate to clamp or release the product 110.

[0037] Through the linkage design of the driving rod 230 and the clamping arm 220, the purpose of clamping or releasing the product 110 by the clamping arm 220 can be achieved by simply controlling the linear movement of the driving rod 230, thereby improving the subsequent processing accuracy of the product 110, and only by applying appropriate external force to change the position of the driving rod 230, the clamping or releasing of the product 110 can be quickly achieved, thereby improving work efficiency.

[0038] Preferably, the product clamping module 200 further includes a compression spring 240 and a locking nut 250. The locking nut 250 is fixed to the lower end of the driving rod 230. The compression spring 240 is sleeved on the driving rod 230, and its two ends respectively abut against the fixing seat 210 and the locking nut 250. When no external force is applied, the compression spring 240 always provides downward force to the driving rod 230 and enables the clamping arm 220 to clamp the product 110.

[0039] That is to say, by setting the compression spring 240, the purpose of automatic clamping is achieved, and no additional power source is required to maintain the clamping state of the product 110, which simplifies the operation process.

[0040] Preferably, the clamping arm 220 is connected to the fixing seat 210 via a rotating pin 260. At the same time, an inclined groove is provided at the lower end of the clamping arm 220, and a driving pin 270 passes through the inclined groove and is connected to the driving rod 230, so that the driving rod 230 can drive the clamping arm 220 to rotate around the rotating pin 260.

[0041] The upper end of the clamping arm 220 has a clamping head 221 , and the clamping head 221 is rotated by the rotation of the clamping arm 220 , thereby clamping or releasing the product 110 .

[0042] Preferably, a product releasing module 300 is further included, which is arranged at the bottom of the product clamping module 200. The product releasing module 300 includes:

[0043] Toggle clamp fixing seat 310 and toggle clamp 320;

[0044] A guide rod 330 connected to the output end of the toggle clamp 320 and moving linearly with the movement of the toggle clamp 320;

[0045] The swing arm mounting seat 340, the swing arm 350 and the support plate 360, the swing arm mounting seat 340 is installed on the guide rod 330, and the two ends of the swing arm 350 are hinged to the swing arm mounting seat 340 and the support plate 360 ​​respectively.

[0046] The lowering and rising of the support plate 360 ​​is controlled by the loosening and clamping of the toggle clamp 320, and the support plate 360 ​​is located at the bottom of the driving rod 230.

[0047] When the toggle clamp 320 is released, the support plate 360 ​​descends and separates from the product clamping module 200. At this time, the driving rod 230 is in the lower position under the action of the compression spring 240, and the clamping head 221 clamps the product 110.

[0048] When the toggle clamp 320 is clamped, the support plate 360 ​​rises and pushes the driving rod 230 upward. At this time, the clamping arm 220 rotates around the rotating pin 260, and the clamping head 221 opens and releases the product 110.

[0049] Specifically, the working principle of the clamping and loosening of the product 110 is as follows:

[0050] 1. Clamping state: When there is no external force, the compression spring 240 acts through the locking nut 250 to keep the driving rod 230 in a downward trend, and the clamping arm 220 swings downward around the rotating pin 260. The upper end of the clamping arm 220 swings inward through the action of the inclined slot to clamp the product 110;

[0051] 2. Relaxed state: When the elbow clamp 320 is activated, the guide rod 330 begins to extend, driving the swing arm mounting base 340 to move. The movement of the swing arm mounting base 340 drives the swing arm 350 to swing, and then drives the support plate 360 ​​to rise. After the support plate 360 ​​rises, it will push up the drive rod 230. When the drive rod 230 rises, the clamping arm 220 rotates around the rotating pin 260. Through the action of the drive pin 270, the inclined groove of the clamping arm 220 causes the upper end of the clamping arm 220 to open outward, releasing the product 110.

[0052] Through the above structural design, the product 110 can be quickly clamped and released.

[0053] In addition, it also includes at least two transverse guide seats 370 and two longitudinal guide seats 380. The transverse guide seat 370 is installed on the guide rod 330, and the longitudinal guide seat 380 is connected to the support plate 360. The transverse guide seat 370 plays a guiding role in the linear movement of the guide rod 330. The longitudinal guide seat 380 is connected to the support plate 360 ​​and plays a guiding role in the up and down movement of the support plate 360.

The above is a specific embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
