[0055] like Figures 1-9 As shown:
[0056] Example 1:
[0057] The positioning fixture includes: a base 2, a reinforcing block 3, a machining block, a positioning pin 6, and a support 7. A base 20 is provided on one side of the base 2, and a machining block is provided on the top surface of the base 20. A machining hole 50 is provided on one side of the machining block. A limiting rod 21 is provided on the other side of the base 2. The base 20 is symmetrically positioned between the limiting rods 21. The limiting rods 21 pass through a groove 70 provided at the bottom of the support 7. The support 7 and the base 20 form a close-fitting structure. A positioning block 72 is provided on the top of the support 7. The positioning blocks 72 have a symmetrical structure, and rollers are symmetrically positioned between the positioning blocks 72 to balance the flow force of material friction. Through the positioning fixture of this application, the material edge is subjected to frictional force from the rollers, resulting in a slower flow at the material edge. Combined with the material center being subjected to frictional force from the machining hole wall, this also results in a slower flow, preventing the material from thinning at both sides.
[0058] The rollers are positioned symmetrically between the positioning blocks 72;
[0059] The roller includes a first rod 8 and a second rod 80, with the second rod 80 passing through the first rod 8, and the first rod 8 and the second rod 80 are connected by threads, which facilitates disassembly and installation.
[0060] The second rod 80 passes through the inside of the outer shell 800. Both the first rod 8 and the second rod 80 have a protruding limiting ring 81 on one side. The limiting ring 81 and the two ends of the outer shell 800 are in contact with each other. However, the limiting ring 81 is clamped between the two limiting rings 81, which helps the outer shell 800 to connect with the first rod 8 and the second rod 80. This facilitates the replacement of the outer shell 800 and is suitable for processing materials of various sizes.
[0061] The first rod 8 has shafts 82 at both ends, and the shafts 82 pass through the shaft holes 720; the bottom surface of the support 7 has a sliding groove 70, and one side has a fixing lock hole 211. The front and back of the support 7 have positioning blocks 72, one end of which protrudes from the support 71. One side of the positioning block 72 has a shaft hole 720, and the shafts 82 pass through the shaft holes 720. However, the rollers pass through the positioning blocks 72 symmetrically, so as to realize the structure that facilitates the disassembly and installation of the rollers.
[0062] The other side of the positioning block 72 is provided with a fixing lock hole 211, and the fixing lock hole 211 provided in the positioning block 72 and the fixing lock hole 211 provided in the support 7 are opposite to each other.
[0063] The support 7, base 20, and reinforcing block 3 are adjacent structures and are in contact with each other; the support 7 adopts a sliding groove 70 and a limiting rod 21 to form a through structure, which is easy to disassemble and install.
[0064] A protruding support rod 71 is provided on one side of the positioning block 72. The wall surface of the support rod 71 is in contact with the wall surface of the reinforcing block 3, thereby increasing the stability of the reinforcing block 3 during installation.
[0065] The base 2 is connected to the processing platform of the wire drawing machine (not shown in the drawing), and it is a structure that can be disassembled and installed.
[0066] The base 20 has a fixing lock hole 211 on the front side. The fixing lock hole 211 on the base 20, the fixing lock hole 211 on the positioning block 72, and the fixing lock hole 211 on the support 7 are at the same level.
[0067] The fixing plate 9 is provided with multiple positioning locking holes 90, which are opposite to the fixing locking holes 211 provided in the base 20, support 7, and positioning block 72, and are connected by bolts; the base 20 is fixed on the frame of the base 2, and the base 20, support 7, and positioning block 72 are connected to the positioning locking holes 90 provided in the fixing plate 9 through the fixing locking holes 211. Since the base 20 and the base 2 are fixed, the stability of the support 7 and positioning block 72 is improved.
[0068] The bottom surface of the base 20 is provided with a protruding key block 200, and the reinforcing block 3 is provided on the top surface of the base 20. The bottom surface of the reinforcing block 3 is provided with a keyway, and the key block 200 passes through the keyway, thus facilitating the disassembly and installation of the base 20.
[0069] The top surface of the reinforcing block 3 is provided with a groove 30 and a reinforcing locking hole 31. The processing block is located on the top surface of the reinforcing block 3. The processing block includes a first block 4 and a second block 5. The bottom surface of the first block 4 is provided with a protruding support leg 40, and the top surface of the first block 4 is provided with a processing locking hole 41. However, the support leg 40 passes through the inside of the groove 30. The reinforcing locking hole 31 on the top surface of the reinforcing block 3 is located on the bottom surface of the groove 30. The reinforcing locking hole 31 and the processing locking hole 41 on the top surface of the first block 4 are opposite to each other and are connected by bolts, which improves the stability of the installation of the first block 4.
[0070] The top surface of the first block 4 is provided with a limiting block 42, and the bottom surface of the second block 5 is provided with a protruding limiting block 42. Both the first block 4 and the second block 5 are L-shaped, and the ends of the limiting block 42 and the second block 5 are attached to each other. The ends of the limiting block 42 and the first block 4 are attached to each other. However, the first block 4 and the second block 5 form an integral structure, and the combination of the first block 4 and the second block 5 forms a rectangular shape.
[0071] The top surface of the second piece 5 is provided with a machining hole 50, which is a hole for placing material for machining;
[0072] The first block 4 has a positioning hole 400 on one side, and the second block 5 has a positioning hole 400 on one side, and the positioning holes 400 provided on the first block 4 and the second block 5 are opposite to each other.
[0073] The positioning holes 400 provided in the first block 4 and the positioning holes 400 provided in the second block 5 are interconnected and connected by bolts, which helps the first block 4 and the reinforcing block 3 to form a structure for disassembly and installation.
[0074] Example 2:
[0075] The positioning pin 6 passes through the positioning holes 400 provided in the first block 4 and the second block 5, and the first block 4 and the second block 5 form an integral structure through the connection of the positioning pin 6;
[0076] The locating pin 6 has a cap 60 at one end, and the locating pin 6 and the cap 60 are assembled into a movable structure.
[0077] The positioning pin 6 has a protruding locking block 61 and a limiting plate 62 at one end, and the cap 60 has a locking groove 600 on one side and a locking position 601 on the other side; the locking block 61 can pass through the locking groove 600, which helps the positioning pin 6 and the cap 60 to form a snap-fit connection structure. However, the positioning pin 6 forms a rotatable structure through the cap 60.
[0078] When the positioning pin 6 rotates, one end of it has already passed into the positioning hole 400 provided in the second block 5. However, the second block 5 has an automatic moving structure driven by the positioning pin 6. It is an automatic centering structure and a structure that is easy to replace.
[0079] The limiting plate 62 is connected to the locking position 601. The locking position 601 has an internal hollow frame structure, and the limiting plate 62 passes through the hollow frame. The cap 60 is movable by the user's stretching.
[0080] Based on the above structure, the cap 60 has two states. In one state, it is engaged with the latch 61 and has a structure that drives the positioning pin 6 to rotate. In the other state, it is engaged with the latch 601, which helps the cap 60 to disengage from the latch 61 and form a movable structure.
[0081] Example 3:
[0082] The base 20 has an inclined structure on one side, and the key block 200 also has an inclined structure. The bottom surface of the reinforcing block 3 has an inclined structure, and the keyway also has an inclined structure. The interlocking connection between the base 20 and the reinforcing block 3 forms an inclined interlocking connection. The inclined interlocking surface can change the direction of force transmission and decompose part of the vertical load into compressive stress along the inclined surface, thereby improving the compressive strength of the structure.
[0083] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
