Abstract
Description
Technical Field
[0001] This utility model relates to precision manufacturing technology, particularly to CNC machining, specifically a lower-level gap positioning upper double-sided tight-push fixture. Background Technology
[0002] See Figure 1 The product 100 shown includes a main plate 101. The upper surface of the main plate 101 has elements that need to be processed, and the lower surface has two lower protruding columns 102. The main plate 101 is square in shape, and the distance between the two lower protruding columns 102 varies in the series of products. Because the two lower protruding columns 102 are at different distances in the series of products, the current method of contour matching requires the preparation of multiple fixtures, which seriously wastes production resources.
[0003] Therefore, it is necessary to provide a double-sided push-type fixture for lower gap positioning to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a double-sided push-type fixture for lower gap positioning.
[0005] The technical solution is as follows: A lower gap positioning upper double-sided tight-push type fixture includes a fixture plate, and the fixture plate is provided with a waist-shaped positioning groove. The positioning groove includes a lower part extending out of the column positioning part A at one end and a lower part extending out of the column positioning part B at the other end, forming a lower side positioning. Corresponding to the lower protruding column positioning part A, the main body plate is provided with an end face pressing positioning module A, which is composed of several pin slots. Corresponding to the lower protruding column positioning part B, the main body plate is provided with an end face pressing positioning module B, which is composed of several pin slots.
[0006] Furthermore, the pin slots of the end face pressing positioning module A are set in at least two groups, referred to as the first end face pressing pin group A and the second end face pressing pin group A.
[0007] Furthermore, the pin slots of the end face pressing positioning module B are arranged in at least two groups, referred to as the first end face pressing pin group B and the second end face pressing pin group B.
[0008] Furthermore, the positioning groove includes a lower precision positioning groove, which is connected to an outwardly expanding ramp-type push-in groove.
[0009] Furthermore, the slope of the outward-expanding ramp-type push-in groove is 10-15°.
[0010] Furthermore, the positioning groove also includes a rounded anti-collision opening groove at the top.
[0011] Compared with existing technologies, this utility model uses a double-sided push-type positioning at the upper part with a lower gap to match the positioning of various products, and has high versatility. Attached Figure Description
[0012] Figure 1 This is a structural diagram of product 100.
[0013] Figure 2 This is a schematic diagram of the structure of this utility model. Detailed Implementation
[0014] Example:
[0015] Please see Figure 2 This embodiment demonstrates a double-sided push-type fixture for lower gap positioning, including a fixture plate 1. The fixture plate 1 is provided with a waist-shaped positioning groove 2. The positioning groove 2 includes a lower protruding column positioning part A21 at one end and a lower protruding column positioning part B22 at the other end, forming a lower positioning. Corresponding to the lower protruding column positioning part A21, the main body plate is provided with an end face pressing positioning module A3, which is composed of several pin slots. Corresponding to the lower protruding column positioning part B22, the main body plate is provided with an end face pressing positioning module B4, which is composed of several pin slots.
[0016] The pin slots of the end face pressing positioning module A3 are set in at least two groups, referred to as the first end face pressing pin group A200 and the second end face pressing pin group A201.
[0017] The pin slots of the end face pressing positioning module B4 are arranged in at least two groups, referred to as the first end face pressing pin group B300 and the second end face pressing pin group B301.
[0018] The positioning groove 2 includes a lower precision positioning groove 5, which is connected to an outwardly expanding ramp-type push-in groove 6.
[0019] The slope of the outward-expanding ramp-type push-in groove 6 is 10-15°.
[0020] The positioning groove 2 also includes a top arc-shaped anti-collision opening groove 7.
[0021] in: The lower protruding column positioning part A21 is used to position one of the two lower protruding columns 102. After positioning, positioning pins are set on the pin holes of the first end face tight push pin group A200 or the second end face tight push pin group A201 to push the side of the main body plate of the product 100 tightly, forming a lower positioning and upper tight push fixation, thus completing the positioning. The lower protruding column positioning part B22 is used to position one of the two lower protruding columns 102. After positioning, positioning pins are set on the pin holes of the first end face tight push pin group B300 or the second end face tight push pin group B301 to push the side of the main body plate of the product 100 tightly, forming a lower positioning and upper tight push fixation, thus completing the positioning.
[0022] Compared with existing technologies, this utility model uses a double-sided push-type positioning at the upper part with a lower gap to match the positioning of various products, and has high versatility.
[0023] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
