Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing equipment technology, and in particular to an adjustable housing processing fixture. Background Technology

[0002] The shell needs to be fixed with a fixture during processing to ensure its stability and accuracy, thereby improving the efficiency of shell processing and meeting the process requirements of shell assembly in the later stage.

[0003] In the prior art, such as the adjustable pump housing processing fixture disclosed in Chinese Patent Publication No. CN219404211U, there is a fixture table. A directional tube is fixedly installed on both side walls of the fixture table. A threaded screw is threadedly connected to the directional tube. Side clamping plates are fixed to the ends of both threaded screws. Several movable clamping parts are installed on both side clamping plates. Each movable clamping part includes a fixed sleeve fixed to the side clamping plate and a movable rod movably mounted on the fixed sleeve via a compression spring. Compared with the prior art, this utility model, by setting directional tubes, threaded screws, side clamping plates, and movable clamping parts on the fixture table, can not only clamp the pump housing to be processed, but also, although the clamped pump housing cannot move arbitrarily, when the user controls the rotation of the support table, it can drive the clamped pump housing to rotate synchronously, thereby realizing the adjustment of the pump housing position during clamping and facilitating comprehensive processing.

[0004] In actual production and use, although this type of adjustable pump housing machining fixture can adjust the position of the clamped housing after fixing it, there may be situations where it is necessary to adjust the height of the clamped housing to meet the process requirements. This type of adjustable pump housing machining fixture does not have a height adjustment device, which makes it impossible to adjust the height of the clamped housing. This may affect the machining effect of the housing, resulting in poor performance of the device. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable fixture for machining housings, which has a good adjustment effect after the housing is clamped.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable housing processing fixture, comprising a base plate, an adjusting plate, a clamping plate, a fixture jaw, a linkage rod, a toothed column, a telescopic rod, and a shaft. The telescopic rod has a toothed groove inside, and straight teeth are fixedly connected inside the toothed groove. The straight teeth mesh with the toothed column. One end of the telescopic rod is fixedly connected to the adjusting plate, and the other end is fixedly connected to the base plate. A rotating rod is fixedly connected to the outside of the toothed column, and a rotating handle is fixedly connected to the outside of the toothed column. A small hole is opened inside the clamping plate, and a cylinder is fixedly connected inside the clamping plate. A slot is opened inside the clamping plate, and a fixture base is fixedly connected inside the slot. The fixture base is rotatably connected to the fixture jaw. A connecting rod is rotatably connected to the outside of the fixture jaw, and the connecting rod is fixedly connected to the linkage rod. The output end of the cylinder is fixedly connected to the shaft. A small rod is fixedly connected to the bottom of the linkage rod, and the small rod passes through the small hole and is fixedly connected to the shaft.

[0007] By adopting the above technical solution, after the worker places the housing under the clamping jaws, they start the cylinder. The output end of the cylinder drives the shaft to move downwards, causing the small rod to drive the linkage rod to move downwards under force. This causes the clamping jaws and the clamping base to rotate, allowing the clamping jaws to clamp and fix the housing. After the housing is clamped and fixed in the slot, when it is necessary to adjust the processing height of the housing, the worker manually turns the handle to rotate the gear column. Through the meshing connection between the gear column and the straight teeth, the straight teeth move vertically upwards, thereby extending the telescopic rod and raising the adjusting plate. This adjusts the processing height of the housing after it is clamped in the slot, making it easier to process the clamped housing later. Through the above operation, a good adjustment effect for the clamped housing is achieved.

[0008] A further feature of this invention is that four pins are fixedly connected inside the slot.

[0009] By adopting the above technical solution, after the housing is placed in the slot, the assembly hole on the housing extends into the interior of the pin, and the pin plays a limiting role in the housing, preventing the housing from moving freely in the slot.

[0010] A further feature of this invention is that a disc is rotatably connected to the upper surface of the adjusting plate, and the disc is fixedly connected to the bottom of the clamping plate.

[0011] By adopting the above technical solution, workers can rotate the disc to make the clamping plate rotate the shell after clamping, and adjust the angle of shell processing.

[0012] A further feature of this invention is that a rotating handle is fixedly connected to the outside of the disc, and the number of rotating handles is two.

[0013] By adopting the above technical solution, the worker was able to rotate the disc by holding the handle.

[0014] A further feature of this invention is that: a limiting hole is provided inside the adjusting plate, a pin is fixedly connected to the outside of the disc, and a plug is provided inside the pin.

[0015] By adopting the above technical solution, after the clamped housing is rotated to a specified angle, the worker inserts the insert into the limiting hole to temporarily limit the disc and prevent the disc from rotating randomly.

[0016] A further feature of this invention is that a ruler plate is fixedly connected to the outside of the telescopic rod, and the upper surface of the ruler plate is provided with a scale.

[0017] By adopting the above technical solution, workers can use the scale on the ruler to provide a reference for adjusting the height of the movement of the clamped shell.

[0018] A further feature of this invention is that a vertical plate is fixedly connected to the upper surface of the base plate, and a circular hole is provided inside the vertical plate, through which the rotating rod passes.

[0019] By adopting the above technical solution, when the tooth column is subjected to force and rotates, it drives the rotating rod to rotate. Through the rotation of the rotating rod in the circular hole, the tooth column and the straight tooth are stably connected during meshing motion, preventing the tooth column and the straight tooth from disengaging.

[0020] A further feature of this invention is that the toothed column has a recessed hole inside, a steel ball is rotatably connected inside the recessed hole, and a limiting arc rod is fixedly connected to the outside of the steel ball.

[0021] By adopting the above technical solution, after the clamped shell is adjusted to the corresponding height, the worker rotates the limiting arc rod by the steel ball, so that the limiting arc rod is stuck between the tooth column and the straight tooth, so that the tooth column and the straight tooth cannot move temporarily, preventing the straight tooth from driving the telescopic rod to move downward under the action of gravity, thus causing the height of the shell to change.

[0022] A further feature of this invention is that: a threaded hole is provided inside the telescopic rod, a locking plate is provided inside the telescopic rod, a torsion head is provided outside the telescopic rod, a stud is fixedly connected to the outside of the torsion head, and the stud passes through the threaded hole and is fixedly connected to the locking plate.

[0023] By adopting the above technical solution, after the clamped shell is adjusted to the corresponding height, the worker rotates the toggle head to make the stud drive the locking plate to move. After the locking plate moves, it pushes against the inner tube of the telescopic rod, which acts as a brake on the telescopic rod to prevent the height of the telescopic rod from changing again.

[0024] A further feature of this invention is that a grip head is fixedly connected to the outside of the handle, and a layer of adhesive cotton is fixedly connected to the upper surface of the grip head.

[0025] By adopting the above technical solution, the cotton layer fixedly connected to the upper surface of the grip makes the worker's hand feel comfortable when holding the grip and turning it, and prevents the handle from injuring the worker's hand.

[0026] The beneficial effects of this utility model are: 1. This utility model, through the arrangement of a base plate, adjusting plate, clamping plate, clamping jaws, linkage rod, toothed column, telescopic rod, toothed groove, straight tooth, rotating rod, handle, small hole, cylinder, slot, clamping base, connecting rod, and shaft, allows the worker to clamp the housing by driving the clamping jaws through the output end of the cylinder. After the worker clamps the housing, the worker rotates the handle to rotate the toothed column. Through the meshing connection between the toothed column and the straight tooth, the straight tooth moves vertically upward, thereby extending the telescopic rod to raise the adjusting plate, thus adjusting the processing height of the clamped housing.

[0027] 2. This utility model, through the arrangement of a pin, disc, handle, limiting hole, insert pin, insert strip, ruler plate, vertical plate, round hole, concave hole, steel ball, limiting arc rod, threaded hole, locking plate, toggle head, stud, grip, and rubber layer, uses the following components: the pin limits the housing; rotating the disc causes the housing to rotate after clamping, adjusting the angle of the housing processing; the handle facilitates the rotation of the disc; after the housing rotates to the specified angle, the insert strip is inserted into the limiting hole to temporarily prevent the disc from rotating arbitrarily; the scale on the ruler plate provides a reference for the adjustment distance; the rotation of the toggle rod in the round hole prevents the toothed column from disengaging from the straight tooth; the worker uses the limiting arc rod to wedge between the toothed column and the straight tooth to prevent the telescopic rod from sliding down under gravity; the worker rotates the toggle head, causing the locking plate to move and press against the inner tube of the telescopic rod, acting as a brake; and the rubber layer protects the worker's hands.

[0031] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] Reference Figure 1-4 An adjustable housing machining fixture includes the following specific embodiments: Example 1: An adjustable housing machining fixture includes a base plate 1, an adjusting plate 2, a clamping plate 3, a clamping jaw 4, a linkage rod 5, a toothed column 6, a telescopic rod 7, and a shaft 17. The telescopic rod 7 has a toothed groove 8 inside, and a straight tooth 9 is fixedly connected inside the toothed groove 8. The straight tooth 9 meshes with the toothed column 6. One end of the telescopic rod 7 is fixedly connected to the adjusting plate 2, and the other end is fixedly connected to the base plate 1. A rotating rod 10 is fixedly connected to the outside of the toothed column 6, and a handle 11 is fixedly connected to the outside of the toothed column 6. The clamping plate 3 has a small hole 12 inside, and a cylinder 13 is fixedly connected inside the clamping plate 3. A slot 14 is formed inside the clamping plate 3, and a fixture base is fixedly connected inside the slot 14. 15. The clamp base 15 is rotatably connected to the clamp jaw 4. The clamp jaw 4 is rotatably connected to the outside of the clamp 16. The connecting rod 16 is fixedly connected to the linkage rod 5. The output end of the cylinder 13 is fixedly connected to the shaft 17. The bottom of the linkage rod 5 is fixedly connected to the small rod 18. The small rod 18 passes through the small hole 12 and is fixedly connected to the shaft 17. After the worker drives the clamp jaw 4 to move and clamp the housing by the output end of the cylinder 13, the worker rotates the handle 11 to make the toothed column 6 rotate. Through the meshing connection between the toothed column 6 and the straight tooth 9, the straight tooth 9 moves vertically upward, thereby causing the telescopic rod 7 to extend and drive the adjusting plate 2 to rise, thereby adjusting the processing height of the clamped housing.

[0033] Example 2: The slot 14 is internally fixedly connected with four pins 19, which limit the position of the housing. The telescopic rod 7 is externally fixedly connected with a ruler 25, the upper surface of which is marked with graduations. The worker uses the graduations on the ruler 25 to provide a reference for adjusting the height of the housing after clamping. The handle 11 is externally fixedly connected with a grip 35, the upper surface of which is fixedly connected with a cotton layer 36. The cotton layer 36 on the upper surface of the grip 35 makes the worker's hand feel comfortable when rotating the grip 35.

[0034] Example 3: A disc 20 is rotatably connected to the upper surface of the adjusting plate 2. The disc 20 is fixedly connected to the bottom of the clamping plate 3. The worker rotates the disc 20 to make the clamping plate 3 drive the rotation of the clamped housing, thereby adjusting the processing angle of the housing. The worker holds the handle 21 to rotate the disc 20. A limit hole 22 is opened inside the adjusting plate 2. A pin 23 is fixedly connected to the outside of the disc 20. A strip 24 is provided inside the pin 23. After the clamped housing is rotated to a specified angle, the worker inserts the strip 24 into the limit hole 22 to temporarily limit the disc 20 and prevent the disc 20 from rotating arbitrarily.

[0035] Example 4: A vertical plate 26 is fixedly connected to the upper surface of the base plate 1. A circular hole 27 is opened inside the vertical plate 26. The rotating rod 10 passes through the circular hole 27. When the toothed column 6 is subjected to force and rotates, it drives the rotating rod 10 to rotate. Through the rotation of the rotating rod 10 in the circular hole 27, the toothed column 6 and the straight tooth 9 are stably connected during meshing, preventing the toothed column 6 and the straight tooth 9 from disengaging. When the toothed column 6 is subjected to force and rotates, it drives the rotating rod 10 to rotate. Through the rotation of the rotating rod 10 in the circular hole 27, the toothed column 6 and the straight tooth 9 are stably connected during meshing, preventing the toothed column 6 and the straight tooth 9 from disengaging.

[0036] Example 5: A recessed hole 28 is provided inside the toothed column 6. A steel ball 29 is rotatably connected inside the recessed hole 28. A limiting arc rod 30 is fixedly connected to the outside of the steel ball 29. After the clamped housing is adjusted to the corresponding height, the worker rotates the limiting arc rod 30 through the steel ball 29, so that the limiting arc rod 30 is locked between the toothed column 6 and the straight tooth 9, so that the toothed column 6 and the straight tooth 9 cannot move temporarily, preventing the straight tooth 9 from driving the telescopic rod 7 downward under the action of gravity, thus changing the height of the housing after adjustment. The telescopic rod 7 has a recessed hole 28 inside. The telescopic rod 7 has a threaded hole 31 and a locking plate 32 inside. The telescopic rod 7 has a toggle head 33 on the outside. A stud 34 is fixedly connected to the outside of the toggle head 33. The stud 34 passes through the threaded hole 31 and is fixedly connected to the locking plate 32. After the clamped housing is adjusted to the corresponding height, the worker rotates the toggle head 33 to make the stud 34 drive the locking plate 32 to move. After the locking plate 32 moves, it pushes against the inner tube of the telescopic rod 7, which acts as a brake on the telescopic rod 7 to prevent the height of the telescopic rod 7 from changing again.

[0037] In this invention, after the worker places the housing under the clamping jaw 4, the cylinder 13 is activated. The output end of the cylinder 13 drives the shaft 17 to move downward, causing the small rod 18 to drive the linkage rod 5 to move downward under force. This causes the clamping jaw 4 and the clamping base 15 to rotate, thus clamping and fixing the housing. After the housing is clamped and fixed in the slot 14, when it is necessary to adjust the processing height of the housing, the worker manually turns the handle 11, causing the toothed column 6 to rotate. Through the meshing connection between the toothed column 6 and the straight tooth 9, the straight tooth 9 moves vertically upward, thereby extending the telescopic rod 7 and raising the adjusting plate 2. This adjusts the processing height of the housing clamped in the slot 14, making it easier to process the clamped housing later. Through the above operations, the clamping height of the housing is adjusted. The housing adjustment effect is excellent. The pin 19 limits the housing. The rotation of the disc 20 drives the rotation of the housing after clamping, and the angle of the housing processing is adjusted. The handle 21 facilitates the rotation of the disc 20. After the housing is rotated to the specified angle, the insert 24 is inserted into the limiting hole 22 to temporarily prevent the disc 20 from rotating randomly. The scale on the ruler 25 provides a reference for the adjustment distance. The rotation of the rotating rod 10 in the round hole 27 prevents the toothed column 6 from disengaging from the straight tooth 9. The worker uses the limiting arc rod 30 to wedge between the toothed column 6 and the straight tooth 9 to prevent the telescopic rod 7 from sliding down under gravity. The worker rotates the twist head 33, which causes the locking plate 32 to move and push against the inner tube of the telescopic rod 7, thus braking the telescopic rod 7. The cotton layer 36 protects the worker's hands.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
