Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy cylinder processing technology, and in particular to a positioning fixture for aluminum alloy cylinders. Background Technology

[0002] Aluminum alloy cylinders are cylindrical structures made of aluminum alloy and are widely used in industrial fields, especially in aerospace, automotive manufacturing, and machining. Aluminum alloy cylinders possess high strength, excellent plasticity and toughness, and good machinability, making them an ideal material for manufacturing complex mechanical parts. However, during the production and processing of aluminum alloy cylinders, external positioning fixtures are often used to clamp and fix the cylinders to improve processing efficiency. Existing positioning fixtures, however, have some problems in their use:

[0003] 1. When clamping and fixing aluminum alloy cylinders of different sizes, the existing positioning fixtures cannot quickly and effectively adapt and fix the aluminum alloy cylinders. It is necessary to manually replace parts or adjust the size to complete the fixing process for aluminum alloy cylinders of different sizes. Such fixing method will reduce work efficiency and waste a lot of time.

[0004] 2. During the processing of existing aluminum alloy cylinders, the high-speed rotating processing equipment comes into contact with the aluminum alloy cylinder, generating a lot of heat through friction. This causes the overall temperature of the aluminum alloy cylinder to rise, and the high temperature of the aluminum alloy cylinder will transfer heat to the positioning fixture, meaning that workers may be at risk of burns when handling the aluminum alloy cylinder. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a positioning clamp for aluminum alloy cylinders.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A positioning fixture for an aluminum alloy cylinder includes a rectangular mounting plate and a cooling fan. An L-shaped fixing bracket is bolted to one side of the top of the rectangular mounting plate, and an annular fixing block is welded to the outer wall of the top side of the L-shaped fixing bracket. The top outer wall of the annular fixing block has rectangular grooves distributed at equal intervals, and a sliding block is slidably inserted into the inner wall of the rectangular groove. An arc-shaped clamping block is welded to the top outer wall of the sliding block, and a rectangular through slot is opened through the bottom inner wall of the rectangular groove. A supporting shaft is rotatably provided at the bottom of the annular fixing block, and a rotating circular plate is welded to the top outer wall of the supporting shaft. An arc-shaped through slot is opened through the top outer wall of the rotating circular plate.

[0008] As a further embodiment of this utility model: guide grooves are opened through both inner walls of the rectangular groove, and guide blocks are welded to both outer walls of the sliding block, and the inner wall size of the guide groove is adapted to the size of the guide block.

[0009] As a further improvement of this utility model: anti-slip rubber pads are adhered to both outer walls of the arc-shaped clamping block, and the outer walls of the anti-slip rubber pads are provided with anti-slip threads.

[0010] As a further embodiment of this utility model: a connecting rod is welded to the outer wall of the bottom of the sliding block, and the diameter of the connecting rod is adapted to the inner wall size of the rectangular through groove and the arc-shaped through groove. A limit block is screwed to the bottom of the connecting rod.

[0011] As a further improvement of this utility model: a circular mounting groove is opened through the top axis of the rotating circular plate, and a cooling fan is installed on the inner wall of the circular mounting groove.

[0012] As a further embodiment of this utility model: a worm gear is welded to the bottom outer wall of the supporting shaft, and a worm is engaged on one side of the worm gear. One end of the worm is connected to a servo motor through a coupling.

[0013] As a further improvement of this utility model: both the cooling fan and the servo motor are connected to a PLC controller via signal lines, and the PLC controller is connected to an external power supply via wires.

[0014] Compared with the prior art, this utility model provides a positioning clamp for aluminum alloy cylinders, which has the following advantages:

[0015] 1. The positioning fixture for the aluminum alloy cylinder in this design uses a servo motor to drive the worm gear to rotate, thereby moving the connecting rod on the rotating circular plate. In conjunction with the rectangular through slot above, the sliding block at the top can be adjusted to allow for quick and adaptive adjustment of the spacing of the arc-shaped clamping blocks. This enables the fixture to clamp and fix aluminum alloy cylinders with different inner diameters.

[0016] 2. The positioning fixture for the aluminum alloy cylinder in this design activates the cooling fan at the shaft center during the adaptive clamping and fixing process of the aluminum alloy cylinder, thereby accelerating the air circulation around it and solving the problem of the aluminum alloy cylinder heating up due to friction, and accelerating the heat dissipation around it.

[0017] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1:

[0025] A positioning fixture for an aluminum alloy cylinder, as described in this embodiment, Figure 1-4 As shown, it includes a rectangular mounting plate 1 and a cooling fan 16. An L-shaped fixing bracket 2 is fixed to one side of the top of the rectangular mounting plate 1 by bolts, and an annular fixing block 3 is welded to the outer wall of the top side of the L-shaped fixing bracket 2. The top outer wall of the annular fixing block 3 has rectangular grooves 4 distributed at equal intervals, and a sliding block 5 is slidably inserted into the inner wall of the rectangular groove 4. An arc-shaped clamping block 6 is welded to the top outer wall of the sliding block 5, and a rectangular through groove 9 is opened through the bottom inner wall of the rectangular groove 4. A supporting rotating shaft 11 is rotatably provided at the bottom of the annular fixing block 3, and a rotating circular plate 12 is welded to the top outer wall of the supporting rotating shaft 11. An arc-shaped through groove 13 is opened through the top outer wall of the rotating circular plate 12, distributed at equal intervals.

[0026] The servo motor 19 drives the worm gear 17 to rotate, thereby moving the connecting rod 10 on the rotating circular plate 12. In conjunction with the rectangular through slot 9 above, the top sliding block can be adjusted to allow for quick and adaptive adjustment of the spacing of the arc-shaped clamping blocks 6. This enables the clamping and fixing of aluminum alloy cylinders with different inner diameters.

[0027] The inner walls of both sides of the rectangular groove 4 are provided with guide grooves 7, and the outer walls of both sides of the sliding block 5 are provided with guide blocks 8. The inner wall size of the guide groove 7 is adapted to the size of the guide block 8. The outer walls of both sides of the arc-shaped clamping block 6 are provided with anti-slip rubber pads, and the outer wall of the anti-slip rubber pads is provided with anti-slip threads.

[0028] A connecting rod 10 is welded to the bottom outer wall of the sliding block 5, and the diameter of the connecting rod 10 is adapted to the inner wall size of the rectangular through groove 9 and the arc-shaped through groove 13. A limit block 14 is screwed to the bottom of the connecting rod 10.

[0029] A circular mounting groove 15 is opened through the top axis of the rotating circular plate 12, and a cooling fan 16 is installed on the inner wall of the circular mounting groove 15.

[0030] When performing adaptive clamping and fixing processing on the aluminum alloy cylinder, the cooling fan 16 at the shaft center is activated to accelerate the air circulation around the cylinder, thereby solving the problem of the aluminum alloy cylinder heating up due to friction and accelerating heat dissipation around the cylinder.

[0031] In this embodiment, the positioning fixture is first placed in the required location, and the rectangular mounting plate 1 is fixed to the location using fastening bolts. Then, the servo motor 19 at the bottom drives the worm gear 18 to rotate, which in turn drives the worm wheel 17 to rotate, thereby driving the bottom support shaft 11 to rotate. This rotation will cause the rotating circular plate 12 above to rotate. Since the inner wall of the arc-shaped through groove 13 is provided with a connecting rod 10, and the upper part of the connecting rod 10 cooperates with the rectangular through groove 9, the connecting rod 10 will move back and forth, realizing the back and forth movement of the top sliding block 5. This will cause the top arc-shaped clamping block 6 to quickly adjust the spacing between them. After adjusting to the spacing that matches the inner wall size of the aluminum alloy cylinder, the aluminum alloy cylinder is fixed. After fixing, it is processed using external processing equipment. During the processing, the cooling fan 16 is activated to accelerate the airflow around, thereby cooling the positioning fixture and the aluminum alloy cylinder.

[0032] Example 2:

[0033] A positioning clamp for an aluminum alloy cylinder, such as Figure 1-4 As shown, this embodiment makes the following additions based on embodiment 1: a worm gear 17 is welded to the bottom outer wall of the supporting shaft 11, and a worm 18 is meshed on one side of the worm gear 17. One end of the worm 18 is connected to a servo motor 19 through a coupling. The cooling fan 16 and the servo motor 19 are both connected to a PLC controller through signal lines, and the PLC controller is connected to an external power supply through wires.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
