Description

Technical Field

[0001] This utility model relates to the field of prototype model technology, and more specifically, it relates to a processing fixture for prototype models. Background Technology

[0002] A prototype is one or more models of an object made based on product appearance or structural drawings before a mold is made. Its main purpose is to check the appearance or structural rationality of the object. When making a prototype model, a jig is needed. The jig is mainly a tool to help control the position or movement of the object. In order to improve the efficiency of prototype model making, a prototype model making jig is needed.

[0003] When machining special-shaped models, due to their complexity, traditional clamping methods often require changing different models of clamping plates and movable clamping blocks. Workers typically need to use specialized tools to disassemble and reassemble the clamps, and each change requires manual adjustment of the clamp's dimensions and positioning. This significantly increases operational complexity and time costs, especially in environments with high production efficiency requirements, where frequent clamp changes become a production bottleneck.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a machining fixture for prototype models, which has the following beneficial effects:

[0017] 1. The clamping mechanism is driven by a motor to rotate the screw, which in turn drives the transmission block to push the clamping plate, enabling the clamping plate to accurately clamp the prototype model. This clamping method allows for quick adjustment of the clamping plate position, and the soft pad design can prevent damage to the model surface during clamping, ensuring the stability and safety of the model during processing. At the same time, the clamping force can be precisely controlled to avoid excessive pressure that could cause model deformation or breakage, thereby improving processing accuracy and reliability.

[0018] 2. The quick-installation mechanism significantly improves the ease of clamp replacement. Through the cooperation of components such as the fixing sleeve, insert rod, and snap-fit ​​rod, the clamp replacement process becomes faster and simpler. The sliding connection design between the insert rod and the fixing sleeve allows the clamp to be quickly disassembled and installed, avoiding the need for cumbersome adjustments using tools in traditional techniques. This greatly shortens the time required to replace the clamp. When replacing the clamp, the cooperation between the guide groove and the guide block of the snap-fit ​​rod ensures the stability and accuracy of the components, avoiding problems such as insecure clamp installation or inaccurate positioning, thus improving the convenience and efficiency of operation.

[0019] 3. The design of the limiting mechanism ensures stable installation and precise positioning of the clamping plate. By rotating the support rod through the rotating sleeve, the limiting mechanism ensures precise alignment of all components during clamping, preventing loosening or displacement of the clamping plate during clamping and guaranteeing processing accuracy. At the same time, the return spring allows the locking rod to quickly disengage from the insertion hole, further simplifying the clamping plate disassembly process. This limiting design not only improves the stability and safety of the fixture but also enhances the overall ease of operation of the device, improving the production efficiency and service life of the equipment.

[0031] A guide block 17 is fixedly provided at the top of the fixed sleeve 8, and a guide groove 18 is provided in each of the snap-fit ​​rods 10.

[0032] Each set of guide blocks 17 has a return spring 19 connected between its bottom surface and the inner side of the guide groove 18. The return spring 19 provides elastic restoring force to ensure that the guide block 17 can automatically reset after movement, avoiding jamming or inaccurate displacement, and maintaining the long-term stable operation of the equipment.

[0037] In this embodiment, the prototype model is placed on the end face of the top plate 29. The motor 3 is started to drive the screw 4 to rotate. The screw 4 and the transmission block 5 are threaded together, thereby pushing the clamping plate 7 so that the soft pad 22 abuts against the outer wall of the prototype model for clamping. When it is necessary to replace the clamping plate 7 with another model, the rotating sleeve 26 is rotated to drive multiple sets of support rods 27 to rotate, so that multiple sets of sliding holes 28 and arc rods 25 respectively release the limit on the connecting frame 13. Multiple sets of return springs 19 pull the snap-fit ​​rod 10 out of the insertion hole 11, releasing the snap-fit ​​on the insertion rod 9. Then the insertion rod 9 can be pulled out of the fixing sleeve 8 and the mounting block 6 to disassemble the clamping plate 7.

[0038] More specifically, when installing the clamping plate 7, the insert rod 9 is inserted into the mounting block 6 and the fixing sleeve 8. The pressure plate 15 is pressed so that its bottom surface abuts against the top of the multiple sets of snap-fit ​​rods 10, and the multiple sets of snap-fit ​​rods 10 are pushed so that they slide along the guide block 17 through the guide groove 18 and are inserted into the insertion hole 11 to snap the insert rod 9. At the same time, the pressure plate 15 drives the connecting frame 13 to slide along the slide groove 14 through the connecting rod 12, so that the multiple sets of arc rods 25 are parallel to the multiple sets of sliding holes 28 respectively. The rotating sleeve 26 drives the multiple sets of support rods 27 to rotate and makes the sliding hole 28 and the arc rod 25 insert into each other, thus completing the limiting of the pressure plate 15.

[0039] In summary, when using or running the entire device: place the prototype model on the end face of the top plate 29, start the motor 3 to drive the screw 4 to rotate, the screw 4 and the transmission block 5 engage in threaded engagement, thereby pushing the clamping plate 7 so that the soft pad 22 abuts against the outer wall of the prototype model for clamping. When it is necessary to replace the clamping plate 7 with another model, rotate the rotating sleeve 26 to drive the multiple sets of support rods 27 to rotate, so that the multiple sets of sliding holes 28 and arc rods 25 respectively release the limit on the connecting frame 13. The multiple sets of return springs 19 pull the snap-fit ​​rod 10 out of the insertion hole 11, releasing the snap-fit ​​on the insertion rod 9. Then the insertion rod 9 can be pulled out of the fixing sleeve 8 and the mounting block 6 to disassemble the clamping plate 7.

[0040] When installing the clamping plate 7, insert the insertion rod 9 into the mounting block 6 and the fixing sleeve 8, press the pressure plate 15 so that its bottom surface abuts against the top of the multiple sets of snap-fit ​​rods 10, and push the multiple sets of snap-fit ​​rods 10 to slide along the guide block 17 through the guide groove 18 and insert them into the insertion hole 11 to snap the insertion rod 9. At the same time, the pressure plate 15 drives the connecting frame 13 to slide along the slide groove 14 through the connecting rod 12, so that the multiple sets of arc rods 25 are parallel to the multiple sets of sliding holes 28 respectively. Rotate the rotating sleeve 26 to drive the multiple sets of support rods 27 to rotate and make the sliding hole 28 insert into the arc rod 25, thus completing the limiting of the pressure plate 15.
