Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and specifically to a shot blasting machine fixture. Background Technology

[0002] A shot blasting machine is a surface treatment device that uses a high-speed rotating impeller to propel shot, which impacts the surface to be treated to achieve cleaning or strengthening. It mainly consists of a shot blasting system, a recovery and separation system, a dust removal system, a control system, and a drive system. Its working principle is as follows: after the workpiece to be cleaned enters the shot blasting chamber and the chamber door is closed, the shot is continuously accelerated by the shot blaster at the top of the chamber and propelled towards the workpiece. The shot is then separated and collected by a transmission device for reuse. The entire process is controlled by the control system.

[0003] The fixtures of a shot blasting machine can accurately determine the position of the workpiece in the machine, ensuring that the workpiece is in the same position each time it is clamped. This ensures that the shot blasting area is accurate and that the treatment effect is consistent and stable. However, during long-term use, the fixtures may deform due to factors such as shot impact, thermal stress, and workpiece clamping force. Deformed fixtures cannot guarantee that the workpiece is in the correct processing position, resulting in uneven shot blasting and affecting the quality of the workpiece.

[0004] Therefore, a shot blasting machine fixture is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a shot blasting machine fixture to solve the problem of fixture deformation caused by impact force.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A shot blasting machine fixture includes a shot blasting machine, with support legs fixedly connected to the bottom of the shot blasting machine, a control mechanism provided on the front side of the shot blasting machine, side plates provided on the left and right sides of the shot blasting machine, a fixture provided on the side of the side plates that are close to each other, a connecting rod fixedly connected to the side of the fixtures that are far apart from each other, a buffer assembly provided on the top of the shot blasting machine, support rods movably connected to the side plates that are close to the fixtures, and a rotating assembly provided on the top of the shot blasting machine.

[0008] Furthermore, the buffer assembly includes a fixed frame 1 fixedly connected to the connecting rod 1 on the opposite side, a fixed rod 1 fixedly connected between the fixed frames 1, a fixed frame 2 fixedly connected to the side of the support rods close to each other, a fixed rod 2 fixedly connected between the fixed frames 2, two sets of movable seats provided on the outer wall surfaces of the fixed rod 2 and the fixed rod 1, a connecting rod 2 hinged between the movable seats, compression springs provided at the front and rear ends of the fixed rod 2, a fixed block fixedly connected to the middle end of the fixed rod 2, and a damper fixedly connected to the side of the fixed blocks close to each other.

[0009] Furthermore, the compression springs are located between the fixed frame two and the movable seat, with their two ends respectively attached to the walls of the movable seat and the fixed frame two.

[0010] Furthermore, the rotating assembly includes a circular plate one fixedly connected to the support rod on the opposite side, a movable rod movably connected between the shot blasting machines, and circular plates two fixedly connected to the left and right sides of the movable rod, with a belt movably connected between circular plates two and circular plate one.

[0011] Furthermore, a stepper motor is fixedly connected to the bottom of the side plate, a rotating shaft is fixedly connected to the output end of the stepper motor, a bevel gear one is fixedly connected to the output end of the rotating shaft, and a bevel gear two is fixedly connected to the left side of the movable rod.

[0012] Furthermore, the front side of the shot blasting machine begins to have a placement groove.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model first controls the fixture to start working, and drives the buffer component to buffer the impact force on the fixture. The buffer component can absorb part of the impact force of the shot, reduce the instantaneous impact force on the workpiece, thereby protecting the integrity and accuracy of the workpiece, and can effectively reduce the impact load on the fixture, extend the service life of the fixture, and reduce the replacement frequency and cost of the fixture. The drive rotating component rotates the fixture, allowing multiple surfaces of the workpiece to be shot blasted in sequence in one clamping, without the need to frequently change the clamping position of the workpiece or re-clamp, thereby saving clamping time and improving the working efficiency of the shot blasting machine.

[0015] 2. This utility model, through the setting of the buffer component, when the clamp is impacted by a projectile and vibrates, the fixed frame one receives the vibration and moves away from each other, the fixed rod one receives the force of the vibration and continues to move outward, the fixed rod one drives the connecting rod two to move away from each other, and the connecting rod two drives the movable seat to compress the springs to move away from each other. During the movement, the movable seat compresses the springs, the springs deform and absorb energy. In the process of spring deformation and energy absorption, the springs reduce the vibration and impact force, effectively reducing the vibration. At the same time, through the resistance of the damper, the clamp is prevented from being damaged by the impact of the projectile. Attached Figure Description

[0022] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

Therefore, they should not be construed as limitations on this utility model.

[0024] like Figures 1 to 3As shown, a shot blasting machine fixture includes a shot blasting machine 1. Support legs 2 are fixedly connected to the bottom of the shot blasting machine 1. A control mechanism 3 is provided on the top front side of the shot blasting machine 1. A placement groove 301 is provided on the front side of the shot blasting machine 1. Side plates 4 are provided on the left and right sides of the shot blasting machine 1. A clamp 401 is provided on the side of the side plates 4 that are close to each other. A connecting rod 402 is fixedly connected to the side of the clamps 401 that are far apart from each other. A buffer assembly 5 is provided on the top of the shot blasting machine 1 to prevent the clamps 401 from being damaged by impact. Support rods 6 are movably connected to the side plates 4 that are close to the clamps 401. A rotating assembly 7 is provided on the top of the shot blasting machine 1 to drive the clamps 401 to rotate.

[0025] It should be noted that, firstly, the control mechanism 3 controls the fixture 401 to start working, and drives the buffer assembly 5 to buffer the impact force received by the fixture 401. The buffer assembly 5 can absorb part of the impact force of the shot, reduce the instantaneous impact force on the workpiece, thereby protecting the integrity and accuracy of the workpiece, and can effectively reduce the impact load on the fixture 401, extend the service life of the fixture 401, and reduce the replacement frequency and cost of the fixture 401. The drive rotation assembly 7 rotates the fixture 401, so that multiple surfaces of the workpiece can be shot blasted in sequence in one clamping, without the need to frequently change the clamping position of the workpiece or re-clamp, thereby saving clamping time and improving the working efficiency of the shot blasting machine 1.

[0026] The buffer assembly 5 includes a fixed frame 501 fixedly connected to the opposite side of the connecting rod 402. Fixed rods 502 are fixedly connected between the fixed frames 501. Fixed frames 503 are fixedly connected to the opposite side of the support rods 6. Fixed rods 504 are fixedly connected between the fixed frames 503. Two sets of movable seats 505 are provided on the outer wall of the fixed rods 504 and the fixed rod 502. Connecting rods 509 are hinged between the movable seats 505. Compression springs 506 are provided at the front and rear ends of the fixed rods 504. Fixed blocks 507 are fixedly connected to the middle end of the fixed rods 504. A damper 508 is fixedly connected to the opposite side of the fixed blocks 507. The output end of the damper 508 is fixedly connected to the wall of the fixed rod 502.

[0027] It should be noted that when the clamp 401 vibrates due to the impact of the projectile, the fixed frame 501 receives the vibration and moves away from each other. The fixed rod 502 receives the force of the vibration and continues to move outward. The fixed rod 502 drives the connecting rod 509 to move away from each other. The connecting rod 509 then drives the movable seat 505 to compress the spring 506 and move away from each other. During the movement, the movable seat 505 compresses the spring 506, causing the spring 506 to deform and absorb energy. In the process of deformation and energy absorption, the spring 506 reduces the vibration and impact force, effectively reducing the vibration. At the same time, the resistance of the damper 508 prevents the clamp 401 from being damaged by the impact of the projectile.

[0028] The rotating assembly 7 includes a circular plate 701 fixedly connected to the support rod 6 on opposite sides. A movable rod 702 is movably connected to the shot blasting machine 1. Circular plates 703 are fixedly connected to the left and right sides of the movable rod 702. A belt 704 is movably connected between the circular plate 703 and the circular plate 701. A stepper motor 705 is fixedly connected to the bottom of the side plate 4. A rotating shaft 706 is fixedly connected to the output end of the stepper motor 705. A bevel gear 707 is fixedly connected to the output end of the rotating shaft 706. A bevel gear 708 is fixedly connected to the left side of the movable rod 702. The bevel gear 708 meshes with the bevel gear 707.

[0029] It should be noted that when the fixture 401 needs to be driven to rotate, the external controller is activated, the stepper motor 705 is activated, and the stepper motor 705 drives the rotating shaft 706 to rotate through the output end. During the rotation of the rotating shaft 706, the first bevel gear 707 rotates, which in turn drives the second bevel gear 708 meshing with it to rotate. During the rotation of the second bevel gear 708, the movable rod 702 rotates, which in turn drives the second circular plate 703 to rotate. During the rotation of the second circular plate 703, the first circular plate 701 is pulled to rotate through the belt 704. In turn, the first circular plate 701 pulls the fixture 401 to rotate through the support rod 6. This allows the fixture 401 to rotate so that the workpiece continuously changes its position and angle during the shot blasting process. The impact point of the shot on the surface of the workpiece also changes continuously, which makes the stress distribution on the surface of the workpiece more uniform.

[0030] In summary: First, the control mechanism 3 controls the fixture 401 to start working, driving the buffer assembly 5 to buffer the impact force on the fixture 401. The buffer assembly 5 can absorb part of the impact force of the shot, reducing the instantaneous impact force on the workpiece, thereby protecting the integrity and accuracy of the workpiece. It can also effectively reduce the impact load on the fixture 401, extend the service life of the fixture 401, and reduce the replacement frequency and cost of the fixture 401. The drive rotation assembly 7 rotates the fixture 401, allowing multiple surfaces of the workpiece to be shot blasted sequentially in one clamping, without the need to frequently change the clamping position of the workpiece or re-clamp, thereby saving clamping time and improving the working efficiency of the shot blasting machine 1.
