Description

Technical Field

[0001] The utility model relates to the technical field of data collector processing equipment, in particular to a positioning fixture for producing a data collector. Background Art

[0002] In the manufacturing process of data acquisition devices, it is necessary to use an angle to fix the processing object so that it occupies the correct position to accept construction or inspection. The device is also called a fixture. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process in the process can be called a fixture.

[0003] During the processing and fixation of the data collector, the fixing effect of the data collector is not ideal, which can easily cause the data collector itself and the fixture to loosen, affecting the positioning and fixing effect of the parts, reducing the processing quality of the parts, and failing to meet the workers' use needs.

[0004] Therefore, in view of the above problems, a positioning fixture for data acquisition production is proposed. Utility Model Content

[0015] The beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0027] A positioning fixture for data acquisition device production includes an upper base plate 3 and a lower base plate 1, a support frame 2 is installed between the upper base plate 3 and the lower base plate 1, a strip hole 31 is opened on the upper base plate 3, two mounting frames 4 are arranged above the strip hole 31, positioning plates 6 are installed on the opposite sides of the two mounting frames 4, each positioning plate 6 is installed with a clamping plate 7, a centering translation assembly for driving the two mounting frames 4 to move in a centering manner is installed on the lower base plate 1, and the centering translation assembly includes a lead screw 10, both ends of the lead screw 10 are rotatably connected to the support frame 2, two support plates 8 threadedly matched therewith are sleeved on the lead screw 10, the tops of the two support plates 8 pass through the upper base plate 3 and are connected to the bottom of the mounting frame 4, and a guide rail 9 for the two support plates 8 to slide left and right is installed on the lower base plate 1.

[0028] In the above structure, each support plate 8 is provided with a threaded hole 81, and the lead screw 10 passes through the threaded hole 81 that cooperates with the threaded hole 81, and the lead screw 10 is driven to rotate to push the left and right support plates 8 to approach each other along the axial direction of the lead screw 10, so that the left and right mounting frames 4 connected to the left and right support plates 8 are displaced in a centering manner, and the positioning plates 6 and clamping plates 7 installed on the left and right mounting frames 4 are synchronously approached to each other, and objects of different volumes placed in the gap between the two clamping plates 7 are clamped, and strip holes 31 are selected to be provided on the upper base plate 3 for the support plates 8 to be inserted therein, which not only limits the support plate 8 itself from rotating with the rotation of the lead screw 10, but also limits the left and right movable distance of the support plate 8; in order to reduce the weight borne by the support plate 8, a guide rail 9 is selected to be installed at the bottom of the lower base plate 1, and the bottom of the support plate 8 can slide on the guide rail 9, so that the subsequent lead screw 10 can better drive the support plate 8 to move left and right.

[0029] In order to better abut the splint 7 against the surface of the object, the following structure is designed:

[0030] A positioning plate 6 is hinged in the middle of the mounting frame 4 , and a standard cylinder 5 for driving the positioning plate 6 to flip is installed on the top of the mounting frame 4 . The end of the piston rod of the standard cylinder 5 is hinged on the positioning plate 6 .

[0031] Subsequently, the standard cylinder 5 pushes the positioning plate 6 to flip downward, and the positioning plate 6 rotates around the hinge between the mounting frame 4 and the positioning plate 6 to drive the clamping plate 7 to abut against the surface of the object and fix the object in the gap between the clamping plate 7 and the upper base plate 3. The positioning plate 6 is pushed to flip by the standard cylinder 5 to adjust the distance between the clamping plate 7 and the upper base plate 3. The standard cylinder 5 needs to adapt to the angle change, so the standard cylinder 5 can be optionally hinged on the top of the mounting frame 4, and the piston rod of the standard cylinder 5 is hinged on the positioning plate 6 through a hinge seat.

[0032] Furthermore, a slot is horizontally opened on the positioning plate 6, and the splint 7 is sleeved in the slot. During installation, the splint 7 only needs to be inserted into the slot of the positioning plate 6, which makes the connection between the two more convenient. Even if the splint 7 is damaged, the splint 7 can be pulled out and a new splint 7 can be inserted to complete the replacement of the parts.

[0033] At the same time, two centering translation assemblies are provided, and the two centering translation assemblies are symmetrically distributed on the front and rear sides of the top surface of the lower base plate 1. The two centering translation assemblies drive the two mounting frames 4 above the upper base plate 3 to carry out the centering movement work more stably.

[0034] In order to better drive the screw 10 to rotate, a hand wheel 11 for driving the screw 10 to rotate is selected to be installed on the side of the support frame 2. Subsequently, the screw 10 can be driven to rotate by manually rotating the hand wheel 11.

[0035] In order to rotate the two lead screws 10 synchronously, the following linkage structure is designed:

[0036] The support frame 2 has an installation groove inside, and synchronous wheels 14 are rotatably connected to the left and right sides of the installation groove. A synchronous belt 13 is connected between the two synchronous wheels 14. One end of the hand wheel 11 is inserted into the installation groove and connected to the synchronous wheel 14.

[0037] Subsequently, only one hand wheel 11 needs to be rotated to drive the corresponding synchronous wheel 14 to rotate in the installation groove, and the left and right synchronous wheels 14 in the installation groove rotate synchronously on the synchronous belt 13, realizing the synchronous rotation of the front and rear lead screws 10, providing convenience for subsequent clamping work.

[0038] Furthermore, the clamping portion of the clamping plate 7 is improved. The end of the clamping plate 7 is an L-shaped block. The L-shaped block has a vertical portion and a horizontal portion. The horizontal portion abuts against the top surface of the object to be clamped, and the vertical portion abuts against the side surface of the object to be clamped.

[0039] In order to reduce the friction resistance caused by the gap between the support plate 8 and the guide rail 9 , a limiting groove 82 for the guide rail 9 to slide is provided at the bottom of the support plate 8 , and a universal ball 12 is installed in the limiting groove 82 .

[0040] The limit groove 82 can limit the device to only move left and right on the guide rail 9, and the universal ball 12 installed in the limit groove 82 is between the support plate 8 and the guide rail 9. When the support plate 8 moves left and right on the guide rail 9, the universal ball 12 can reduce the friction resistance and wear between the two.
