Technical Field

[0001] The utility model relates to the field of sole manufacturing, and more specifically to a fixture for testing 3D printed shoe midsoles. Background Art

[0002] In the existing technology, the performance of 3D printed shoe midsoles needs to be tested after printing;

[0003] During the traditional testing process, the 3D printed shoe midsole is manually placed, and the traditional positioning tooling clamps the two sides of the 3D printed shoe midsole to position it;

[0004] However, during use, there are many inspection points on the 3D printed shoe midsole, and the accuracy requirements are relatively high. The manual placement method cannot meet the high-precision positioning requirements of the 3D printed shoe midsole. The traditional positioning tooling affects the inspection of the upper surface of the 3D printed shoe midsole and is not suitable for testing 3D printed shoe midsoles of various sizes.

[0005] Therefore, how to provide a new 3D printed shoe midsole testing fixture that can meet the positioning accuracy and detection area requirements of the 3D printed shoe midsole during the detection process, and can be adapted to 3D printed shoe midsoles of various sizes while accurately limiting and automatically clamping, is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0006] In view of this, the present invention provides a fixture for testing 3D printed shoe midsoles, aiming to solve the technical problems mentioned above in that traditional fixtures are not accurately positioned during the testing process and cannot adapt to 3D printed shoe midsoles of various sizes.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0075] Specifically, the rotary and telescopic cylinder 51 is installed on the upper surface of the lower plate 13 .

[0076] The specific principles and usage of the 3D printed shoe midsole testing fixture provided in this embodiment are as follows:

[0077] 1. Manually drive the handle 321 to move the sliding base 322 away from the rear limit block 21 until the distance between the elastic clamping surface of the side floating chuck 43 and the rear limit block 21 can accommodate the 3D printed shoe midsole being tested;

[0078] 2. Manually place the 3D printed shoe midsole onto the clamping area of platform 11, with the rear end of the 3D printed shoe midsole in contact with the rear stopper 11 and the side of the 3D printed shoe midsole in contact with the side stopper 22;

[0079] 3. The controller drives the cylinder 45 to retract, and the clamping bracket 41 drives the side floating chuck 43 to clamp the side of the 3D printed shoe midsole;

[0080] 4. Manually drive the handle 321 to move the sliding base 322 in a direction approaching the rear limit block 21. After the elastic clamping surface of the side floating chuck 43 contacts the front end of the 3D printed shoe midsole, the sensor feedback bracket 312 and the proximity sensor 313 undergo displacement changes. The proximity sensor 313 transmits a signal to the controller, which controls the power control switch to energize the electromagnet 33. The electromagnet 33 is attracted to the upper plate 11, completing the locking of the 3D printed shoe midsole in the length direction by the front clamping mechanism 3.

[0081] 5. The controller drives the rotary telescopic cylinder 51 to contract. The rotary telescopic cylinder 51 drives the pressing plate 53 to rotate from the side of the 3D printed shoe midsole to directly above the 3D printed shoe midsole, and descends during the rotation process, pressing the 3D printed shoe midsole in the thickness direction to complete the locking of the 3D printed shoe midsole.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
