Description

Technical Field

[0001] This utility model belongs to the field of brake manufacturing technology, and in particular relates to a bolt tightening device for assembling the functional parts of a brake with a flange. Background Technology

[0002] A brake is a device that functions to decelerate, stop, or maintain a stopped state of moving parts (or moving machinery). It is a mechanical part that stops or decelerates moving parts in machinery. During the brake manufacturing process, its functional components (such as the brake drum in a drum brake or the brake disc in a disc brake) need to be combined with a flange to facilitate the later assembly of the brake system on the product. The functional components and the flange are typically connected using bolts.

[0003] The conventional assembly method involves placing the functional part of the brake and the flange into a positioning fixture that can rotate horizontally. After the bolts are pre-assembled (usually inserted into the pre-drilled holes on the flange and slightly connected to the threaded holes on the functional part of the brake), a lifting assembly controls a sleeve (screwdriver) to tighten the bolts under the drive of a motor.

[0004] During actual use, the applicant found that existing positioning fixtures are usually placed horizontally, which requires a lot of force from the arms during loading and unloading. Therefore, the applicant designed a device that can reduce the intensity of loading and unloading for workers. Utility Model Content

[0005] The purpose of this utility model is to provide a bolt tightening device for assembling the brake functional part with the flange, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, one technical solution adopted by this utility model is: a bolt tightening device for assembling a brake functional part with a flange, comprising a worktable, a positioning fixture, a rotating assembly, a lifting assembly, and an assembly assembly. The rotating assembly includes a rotary drive assembly disposed on the worktable and a turntable disposed at its drive end. A mounting plate is hinged to the turntable. The positioning fixture is disposed on the mounting plate and moves therewith. The lifting assembly is used to lift the mounting plate so that it can rotate relative to the turntable. The assembly assembly includes a lifting assembly disposed on the worktable and a tightening head disposed at the lifting end of the lifting assembly.

[0007] Preferably, the lifting assembly includes a lifting cylinder mounted on the workbench, and the working end of the lifting cylinder is provided with a roller.

[0008] Preferably, the mounting plate is provided with a limiting groove, and the roller slides in the limiting groove during the lifting process. The roller and the limiting groove are in clearance fit, and the gap between the two in the axial direction of the roller is less than 1mm.

[0009] Preferably, the worktable is provided with a positioning drive component and a positioning pin disposed at the driving end of the positioning drive component, the turntable and the mounting plate are provided with coaxial positioning holes for use with the positioning pin, and the end of the positioning pin is chamfered.

[0010] Preferably, the turntable is provided with a buffer element that can cushion the placement tray.

[0011] Preferably, the mounting plate is provided with a hinge block, the turntable is provided with a hinge seat, the hinge seat and the hinge block are connected by a rotating shaft, the rotating shaft is fitted with a bearing, and the fit clearance between the hinge seat and the hinge block in the axial direction of the rotating shaft is less than 1mm.

[0012] Preferably, the worktable is provided with a horizontal X-axis linear moving component, and the lifting component is located at the moving end of the horizontal X-axis linear moving component.

[0013] The beneficial effects of this utility model are as follows: By setting up a lifting component, the mounting plate is lifted during the loading and unloading process, so that it is tilted at an angle with the turntable. In this way, the workers need to exert less force when loading and unloading materials, thus reducing the labor intensity.

[0014] By incorporating rollers, hard contact with the placement tray can be avoided, thus preventing (or reducing) damage between the two.

[0015] In the conventional connection between the tightening head and the bolt, the effect of the chamfer and other structures usually allows them to fit within an error range of 1-2mm. Therefore, by limiting the fit clearance between the limiting groove and the roller, it can be ensured that the tightening head and the bolt can fit properly. Similarly, the parameter limitation of the hinge seat and the hinge block is also based on this reason. It should also be noted that by sleeved bearings on the rotating shaft, the rotation between the hinge block and the hinge seat can be made smoother.

[0016] By setting positioning pins, errors can be further eliminated when the placement plate is attached to the turntable. Attached Figure Description

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0025] Example:

[0026] See Figure 1 A bolt tightening device for assembling a brake functional part with a flange includes a worktable 1. The worktable 1 is provided with a positioning fixture 8, a rotating assembly, a lifting assembly, and an assembly assembly. The rotating assembly includes a rotary drive assembly 5 disposed on the worktable 1 and a turntable 6 disposed at its drive end. A mounting plate 7 is hinged to the turntable 6. The positioning fixture 8 is disposed on the mounting plate 7 and moves with it. The lifting assembly is used to lift the mounting plate 7 so that it can rotate relative to the turntable 6. The assembly assembly includes a lifting assembly 3 disposed on the worktable 1 and a tightening head 4 disposed at the lifting end of the lifting assembly 3. The rotary drive assembly 5 can be a rotary motor fixed on the worktable 1. The lifting assembly can be a linear cylinder. The tightening head 4 can be a sleeve or screwdriver that can tighten the bolt.

[0027] See Figure 6 In this embodiment, the positioning fixture 8 consists of four pins 21 fixed on the mounting plate 7 and two positioning blocks 20. The ends of the pins 21 are chamfered to serve as guides. The brake function part has positioning grooves 22 and sidewalls that respectively cooperate with the pins 21 and the positioning blocks 20.

[0028] Among them, see Figure 1 The workbench 1 is provided with a horizontal X-axis linear moving component 2, and the lifting component 3 is provided at the moving end of the horizontal X-axis linear moving component 2. The horizontal X-axis linear moving component 2 can be a linear moving mechanism driven by a motor or cylinder. The setting of this structure can enhance the spatial flexibility of the assembly component, so that the equipment is still applicable when tooling adapted to different specifications of workpieces is installed on the mounting plate 7.

[0029] Among them, see Figure 2 , Figure 3 The lifting assembly includes a lifting cylinder 9 mounted on the workbench 1. The working end of the lifting cylinder 9 is provided with a roller 10. The roller 10 can be a bearing 19 to improve strength and stability. The mounting plate 7 is provided with a limiting groove 11. The roller 10 slides in the limiting groove 11 during the lifting process. The roller 10 and the limiting groove 11 are in clearance fit, and the gap between the two in the axial direction of the roller 10 is less than 1mm. The round edge of the roller 10 is chamfered to facilitate entering the limiting groove 11.

[0030] Among them, see Figure 2 , Figure 3 The worktable 1 is provided with a positioning drive assembly 12 and a positioning pin 13 located at the driving end of the positioning drive assembly 12. The turntable 6 and the mounting plate 7 are provided with coaxial positioning holes 14 that cooperate with the positioning pin 13. The end of the positioning pin 13 is chamfered. The positioning drive assembly 12 can be a linear cylinder. Multiple positioning holes 14 can be provided on the turntable 6 and the mounting plate 7 at the single rotation position of the turntable 6, and they can all use one positioning drive assembly 12 and positioning pin 13, so that positioning can be performed before each assembly operation. Of course, based on the workpiece, the weight of the mounting plate 7 itself, etc., positioning is only required when the mounting plate 7 is reset.

[0031] Among them, see Figure 4 The turntable 6 is provided with a buffer element 15 that can buffer the placement plate 7. The buffer element 15 can be a spring or the like, and its maximum elastic force is less than the weight of the placement plate 7. It only serves to buffer and reduce noise. Specifically, a placement groove can be opened on the turntable 6, and the buffer can be placed in the placement groove. In its natural state, one end extends out of the placement groove. After compression, it retracts into the placement groove without affecting the fit between the placement plate 7 and the turntable 6.

[0032] Among them, see Figure 5The mounting plate 7 is provided with a hinge block 16, and the turntable 6 is provided with a hinge seat 17. The hinge seat 17 and the hinge block 16 are connected by a rotating shaft 18. A bearing 19 is sleeved on the rotating shaft 18. The fit clearance between the hinge seat 17 and the hinge block 16 in the axial direction of the rotating shaft 18 is less than 1mm. Specifically, after installation, the rotating shaft 18 is fixed on the hinge block 16, the outer ring of the bearing 19 fits with the hole at the beginning of the hinge seat 17, and the inner ring of the bearing 19 fits with the rotating shaft 18. To ensure the connection strength, multiple hinge blocks 16 can be provided.

[0033] Working principle and process:

[0034] When using the equipment of this solution, adjust the operating parameters of the horizontal X-axis linear moving component 2, the horizontal Y-axis linear moving component, and the assembly component according to the parameters of the positioning fixture 8, start the equipment, and the lifting cylinder 9 will first lift the placement plate 7 to tilt it, preferably at an angle of 30-45°. Then the worker loads and adjusts the material. Afterwards, the lifting cylinder 9 controls the placement plate 7 to reset, and the positioning drive component 12 controls the positioning pin 13 to perform position correction. Then the assembly component works to combine the flange and brake disc functional parts. Afterwards, the assembly component resets, and the lifting cylinder 9 lifts the placement plate 7 to facilitate the worker unloading the material.
