[0003] In the process of finishing parts, how to position and process the parts is a problem that the staff must face. For shell parts with irregular shapes, as shown in the attached figure of the manual, Figure 4 As shown, the traditional positioning method cannot position the parts well. The shell parts are prone to movement during the processing, which affects the quality of the shell parts after processing. Therefore, a shell part positioning fixture is proposed to solve the above problem. Utility Model Content
[0004] In response to the deficiencies of the prior art, the present application provides a housing part positioning fixture having the advantages of being able to clamp and fix irregular housing parts, thereby solving the problem of being inconvenient to clamp and fix irregular housing parts.
[0005] To achieve the above-mentioned purpose, the present application proposes the following technical solution: a housing part positioning fixture, comprising a base and a housing part, wherein a positioning assembly is provided at the top of the base;

[0011] By adopting the above technical solution, the spacing between the two groups of abutment blocks and the normal position of the front and rear abutment blocks can be adjusted to determine whether they are at the same level, so that the two groups of abutment blocks and the two groups of pressure heads can clamp and fix the special-shaped shell parts while also clamping and fixing the normal rectangular shell parts, which can effectively improve the scope of use.
[0012] Furthermore, L-shaped slots are provided at both left and right ends of the top of the base for the card blocks to extend into, and sliding holes are provided at the lower ends of the two groups of abutment blocks for the connecting plates to extend out of.
[0013] The above technical solution is adopted so that the connecting plate can drive the card block to move left and right outside the abutment block, and when the card block moves into the protruding end of the L-shaped slot, the abutment block can be fixed to the top of the base.

[0018] Furthermore, the opposite walls of the left and right groups of abutment blocks are each provided with an elongated hole for allowing the screw rod to extend out of the interior thereof, and the screw rod is slidably connected to the interior of the elongated hole.
[0019] By adopting the above technical solution, the screw rod can pass through the interior of the abutment block, so that when the staff drives the screw rod to move up and down in the long hole, the screw rod can drive the shift rod to move up and down in the abutment block.
[0020] Furthermore, the abutment block is a hollow rectangle, and the upper and lower ends of the two limit rods on the same side are fixed to the upper and lower walls of the inner cavity of the abutment block, and the left and right ends of the top of the shift rod are provided with circular holes for the limit rod to pass through.
[0021] By adopting the above technical solution, the shift rod can move on the outer surfaces of the two limiting rods on the same side through the two circular holes, so as to limit the moving range of the shift rod in the abutment block to prevent the shift rod from moving back and forth in the abutment block.
[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0032] Two sets of adjustment holes 35 are respectively formed at the top ends of the two sets of abutment blocks 31. Bolts 33 are slidably connected to the insides of the adjustment holes 35. The pressure head 32 is located at the top end of the abutment block 31, so that the pressure head 32 can move on the outer surface of the bolt 33 through the adjustment holes 35 to fine-tune the position of the pressure head 32. After fine-tuning, the fastening nut 34 is sleeved on the outer surface of the bolt 33 and threadedly connected thereto. The fastening nut 34 is allowed to abut against the top of the pressure head 32, so that the two pressure heads 32 can be fixed to the top ends of the abutment block 31.
[0033] See also Figures 1 to 3 The adjustment structure in this embodiment includes two groups of blocks 36, two groups of cross bars 38, a connecting plate 37 fixedly installed on the opposite ends of the left and right groups of blocks 36, a shift rod 39 fixedly installed on the outer surface of the cross bar 38, and a screw 311 fixedly installed on the opposite ends of the left and right groups of shift rods 39. The outer surface of the screw 311 is threadedly connected with a positioning nut 312, and the interior of the shift rod 39 is slidably connected to two limit rods 310.
[0034] Secondly, L-shaped slots are provided at both ends of the top of the base 1 for the card block 36 to extend into the interior thereof. The card block 36 moves into the protruding end of the L-shaped slot, so that the abutment block 31 can be fixed to the top of the base 1, so that the card block 36 moves into the L-shaped slot at the corresponding position, and the position of the abutment block 31 can be changed, so that the position of the left and right groups of abutment blocks 31 can be adjusted according to the shape of the shell part 2, and the protruding ends of the left and right groups of L-shaped slots are relative, and the lower ends of the two groups of abutment blocks 31 are provided with sliding holes for the connecting plate 37 to extend out of the interior thereof. The connecting plate 37 can pass through the interior of the first abutment block 31 through the sliding hole, so that the connecting plate 37 is connected to the card block 36, thereby facilitating the connecting plate 37 to drive the card block 36 to move left and right at the lower end of the abutment block 31.
[0035] In addition, a connecting hole is provided at the front end of the shift rod 39 for the cross bar 38 to pass through.

[0036] At the same time, the connecting plate 37 is concave in shape so that the shift rod 39 can move up and down on the inner side of the connecting plate 37. The front and rear ends of the connecting plate 37 are provided with inclined holes for the cross bar 38 to pass through the interior thereof. The front and rear ends of the cross bar 38 are located on the inner sides of the two inclined holes, so that the cross bar 38 can move up and down inside the connecting plate 37. When the left and right groups of cross bars 38 move to the top ends of the corresponding two inclined holes, the left and right groups of cross bars 38 can drive the left and right groups of connecting plates 37 to move back to back. When they move to the lower ends of the inclined holes, they can drive the left and right groups of connecting plates 37 to move relative to each other, so that the left and right groups of connecting plates 37 can drive the left and right groups of card blocks 36 to move relative to or back to each other, so that the left and right groups of card blocks 36 can move out of or into the protruding ends of the L-shaped slots of the base 1.
[0037] In addition, the opposite walls of the left and right groups of abutment blocks 31 are each provided with a long hole for the screw rod 311 to extend out of the interior thereof, and the screw rod 311 is slidably connected to the interior of the long hole so that the screw rod 311 can pass through the interior of the abutment block 31, so that when the staff drives the screw 311 to move up and down in the long hole, the screw 311 can drive the shift rod 39 to move up and down in the abutment block 31, and it is convenient to sleeve the positioning nut 312 on the screw rod 311, so that when the positioning nut 312 abuts against the abutment block 31, the positioning nut 312 can fix the screw 311 in the long hole, thereby positioning the shift rod 39 in the abutment block 31.
[0038] In addition, the abutment block 31 is a rectangle with a hollow interior, and the upper and lower ends of the two limit rods 310 on the same side are fixed to the upper and lower walls of the inner cavity of the abutment block 31. The left and right ends of the top of the shift rod 39 are provided with circular holes for the limit rod 310 to pass through the interior, so that the shift rod 39 can move on the outer surface of the two limit rods 310 on the same side through the two circular holes, so as to limit the movement range of the shift rod 39 in the abutment block 31 to prevent the shift rod 39 from moving back and forth in the abutment block 31, and the connecting plate 37 is located between the two limit rods 310 on the same side to prevent the two limit rods 310 from obstructing it when the shift rod 39 drives the connecting plate 37 to move left and right through the cross bar 38.
