Description

Technical Field

[0001] This utility model relates to the field of polishing, and in particular to a surface treatment device. Background Technology

[0002] A grinding device is a type of equipment used for surface processing. It is mainly used to remove burrs, oxide layers, rust, coatings, or uneven parts from the surface of a workpiece to achieve the required surface finish or shape. The valve core of a valve often rotates with the help of a bearing, and bearings, as a type of casting, often require surface grinding.

[0003] During bearing processing, miniature bearings are placed on a support on the worktable surface and then moved to the rotating grinding roller for surface grinding. However, after grinding, these miniature bearings are prone to shifting and falling off during placement, preventing the entire batch from being processed quickly and efficiently. This inefficient process affects the grinding efficiency of the next batch. Utility Model Content

[0004] The technical problem this invention aims to solve is that after the micro-bearings are polished, they are easily moved and lost during placement due to force, which leads to the inability to quickly and efficiently process all of a batch of micro-bearings, thus affecting the polishing efficiency of the next batch of micro-bearings.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a surface treatment equipment for valve castings, including a workbench and a fixing component. A support is provided on one side of the workbench, and a grinding roller is provided on the side of the workbench near the support. The workbench is provided with a guiding and collecting device by means of the fixing component. The guiding and collecting device guides and collects the ground micro-bearings through a collecting frame and a guiding plate.

[0006] The effect achieved by the above components is as follows: when processing the bearing, the miniature bearing is placed on the support on the surface of the worktable, and then the miniature bearing is moved to the rotating grinding roller. Then the outer surface of the miniature bearing is ground. After the miniature bearing is separated from the support, it enters the guide collection device that is fixed to one side of the worktable by the fixing component for guided and centralized processing.

[0007] Preferably, the guiding and collecting device includes a collecting frame, a square tube, a connecting frame, a guide plate, and a first bolt. The collecting frame is located on one side of the workbench, the square tube is located inside the collecting frame, and the connecting frame moves inside the square tube to move the guide plate at one end closer to the bracket outlet. Several threaded grooves are opened on one side of the connecting frame, and the first bolt is inserted into the square tube and reaches into the threaded groove on one side of the connecting frame to fix the position of the connecting frame and the guide plate.

[0008] The effect achieved by the above components is as follows: When using the guiding collection device, the collection frame is fixed to one side of the workbench by the fixing component. Then, the connecting frame is moved so that it slides in the square tube fixed inside the collection frame. Then, the guide plate fixed on one side of the connecting frame reaches the lower end of the bracket outlet. Then, the first bolt is rotated so that it passes through the square tube and reaches the threaded groove on one side of the connecting frame to fix the connecting frame with threads. After the micro-bearing is ground and detached from the bracket, it will fall onto the surface of the guide plate and be carried by the guide plate to the inside of the collection frame for centralized processing. By using the guiding collection device, the position of the ground micro-bearing can be guided so that the micro-bearing is sent to the inside of the collection frame for centralized processing, avoiding the micro-bearing from moving under force and affecting the subsequent grinding of a batch of micro-bearings, thereby improving the grinding efficiency of the collection device for micro-bearings.

[0009] Preferably, a baffle is provided on one side of the guide plate, and the baffle limits and blocks one side of the guide plate.

[0010] The effect achieved by the above components is that by fixing a baffle on one side of the guide plate, the micro bearing on the guide plate is limited after it reaches the guide plate, so that the micro bearing can better reach the inside of the collection box.

[0011] Preferably, a buffer block is provided on one side of the guide plate, and the surface of the buffer block is arc-shaped.

[0012] The effect achieved by the above components is that by fixing the buffer block inside the guide plate, the movement speed of the micro-bearing inside the guide plate is reduced, thereby reducing the impact force of the micro-bearing when it reaches the collection frame.

[0013] Preferably, a connecting rope is provided on one side of the first bolt, and the connecting rope connects the first bolt to the square tube.

[0014] The effect achieved by the above components is to fix the first bolt and the square tube at both ends of the connecting rope, so as to prevent the first bolt from being lost and affecting its subsequent use.

[0015] Preferably, the collection frame has through holes on both sides, which increases the contact area between the operator and the collection frame.

[0016] The effect achieved by the above-mentioned components is that by opening through holes on both sides of the collection frame, the operator can better grip the collection frame, and then it is convenient to move the miniature bearings inside the collection frame.

[0017] Preferably, the fixing component includes a fixing plate and a second bolt. The fixing plate is disposed on one side of the workbench, and the second bolt is inserted into the fixing plate to fix the position of the collection frame.

[0018] The effect achieved by the above components is as follows: when using the guide collection device, the collection frame can be placed on the upper part of the fixed plate, and then the second bolt can be rotated to make the second bolt pass through the fixed plate and be threaded to the collection frame, thus completing the fixation of the collection frame on one side of the workbench. The guide collection device can be quickly fixed to one side of the workbench, making it convenient for operators to use the guide collection device later.

[0019] Preferably, an operating block is provided on one side of the second bolt, and the operating block raises the dimension of one side of the second bolt.

[0020] The effect achieved by the above components is to increase the size of one side of the second bolt by fixing the operating block on one side of the second bolt, making the second bolt easier to rotate.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] By using a guiding collection device, the polished miniature bearings can be guided to a position, allowing them to be sent into the collection frame for centralized processing. This prevents the miniature bearings from moving under force, which could affect the subsequent polishing of a batch of miniature bearings, thereby improving the polishing efficiency of the collection device.

[0023] The guide collection device can be quickly fixed to one side of the workbench, making it convenient for operators to use the guide collection device later. Attached Figure Description

[0032] Figures 1 to 4 The valve casting surface treatment equipment shown includes a worktable 1 and a fixing assembly 5. A support 2 is provided on one side of the worktable 1, and a grinding roller 3 is provided on the side of the worktable 1 near the support 2. A guiding and collecting device 4 is provided on the worktable 1 via the fixing assembly 5. The guiding and collecting device 4 guides and collects the ground miniature bearings through a collecting frame 41 and a guide plate 44. During bearing processing, the miniature bearing is placed on the support 2 on the surface of the worktable 1, and then moved until it reaches the grinding roller 3, which is rotated by a motor on the surface of the worktable 1. The outer surface of the miniature bearing is then ground. After the miniature bearing detaches from the support 2 and is fixed by the fixing assembly 5 into the guiding and collecting device 4 on one side of the worktable 1, it undergoes guided and collected processing.

[0033] Figures 1 to 4The guide collection device 4 shown includes a collection frame 41, a square tube 42, a connecting frame 43, a guide plate 44, and a first bolt 45. The collection frame 41 is located on one side of the workbench 1, the square tube 42 is located inside the collection frame 41, the connecting frame 43 moves inside the square tube 42 to drive the guide plate 44 at one end to approach the outlet of the bracket 2, and several threaded grooves 46 are opened on one side of the connecting frame 43. The first bolt 45 is inserted into the square tube 42 and reaches into the threaded grooves 46 on one side of the connecting frame 43 to fix the position of the connecting frame 43 and the guide plate 44. When using the guide collection device 4, the collection frame 41 is fixed to one side of the workbench 1 by the fixing component 5. Then, the connecting frame 43 is moved so that it slides in the square tube 42 fixed inside the collection frame 41. Then, the guide plate 44 fixed on one side of the connecting frame 43 reaches the lower end of the outlet of the bracket 2. Then, the first bolt 45 is rotated so that the first bolt 45 passes through the square tube 42 and reaches the threaded groove 46 on one side of the connecting frame 43 to thread-fix the connecting frame 43. After the micro bearing is ground and detached from the bracket 2, it will fall onto the surface of the guide plate 44 and be carried by the guide plate 44 to the inside of the collection frame 41 for centralized processing. By using the guide collection device 4, the position of the ground micro bearing can be guided so that the micro bearing is sent to the inside of the collection frame 41 for centralized processing, avoiding the micro bearing from moving under force and affecting the subsequent grinding of a batch of micro bearings, thereby improving the grinding efficiency of the collection device for micro bearings.

[0034] Figures 1 to 4 A baffle 47 is provided on one side of the guide plate 44, which limits and blocks one side of the guide plate 44. By fixing the baffle 47 to one side of the guide plate 44, the miniature bearing on the guide plate 44 is limited after reaching the guide plate 44, allowing the miniature bearing to reach the inside of the collection frame 41 more effectively. A buffer block 48 is provided on one side of the guide plate 44, and the surface of the buffer block 48 is arc-shaped. By fixing the buffer block 48 inside the guide plate 44, the moving speed of the miniature bearing inside the guide plate 44 is reduced, thus reducing the impact force when the miniature bearing reaches the inside of the collection frame 41. A connecting rope 49 is provided on one side of the first bolt 45, which connects the first bolt 45 to the square tube 42. The two ends of the connecting rope 49 are fixed to the first bolt 45 and the square tube 42 to prevent the first bolt 45 from being lost and affecting its subsequent use. Through holes 410 are opened on both sides of the collection frame 41, which increase the contact area between the operator and the collection frame 41. By opening through holes 410 on both sides of the collection frame 41, the operator can better grip the collection frame 41, and then it is convenient to move the miniature bearing inside the collection frame 41.

[0035] Figures 1 to 4The fixing component 5 shown includes a fixing plate 51 and a second bolt 52. The fixing plate 51 is disposed on one side of the workbench 1, and the second bolt 52 is inserted into the fixing plate 51 to fix the position of the collection frame 41. When using the guide collection device 4, the collection frame 41 can be placed on the upper end of the fixing plate 51, and then the second bolt 52 can be rotated to make the second bolt 52 pass through the fixing plate 51 and be threadedly fixed to the collection frame 41. This completes the fixation of the collection frame 41 on one side of the workbench 1, and the guide collection device 4 can be quickly fixed to one side of the workbench 1, making it convenient for operators to use the guide collection device 4 subsequently.

[0036] Figures 1 to 4 An operating block 53 is provided on one side of the second bolt 52 shown. The operating block 53 raises the dimension of one side of the second bolt 52. By fixing the operating block 53 to one side of the second bolt 52, the dimension of one side of the second bolt 52 is raised, making the second bolt 52 easier to rotate.

[0037] Working principle: When processing the bearing, the miniature bearing is placed on the support 2 on the surface of the worktable 1, and then the miniature bearing is moved to the rotating grinding roller 3. Then the outer surface of the miniature bearing is ground. After the miniature bearing is separated from the support 2, it is fixed to the guide collection device 4 on one side of the worktable 1 by the fixing component 5 for guided collection processing. When using the guide collection device 4, the collection frame 41 is fixed to one side of the workbench 1 by the fixing component 5. Then, the connecting frame 43 is moved so that it slides in the square tube 42 fixed inside the collection frame 41. Then, the guide plate 44 fixed on one side of the connecting frame 43 reaches the lower end of the outlet of the bracket 2. Then, the first bolt 45 is rotated so that the first bolt 45 passes through the square tube 42 and reaches the threaded groove 46 on one side of the connecting frame 43 to thread-fix the connecting frame 43. After the micro bearing is ground and detached from the bracket 2, it will fall onto the surface of the guide plate 44 and be carried by the guide plate 44 to the inside of the collection frame 41 for centralized processing. By using the guide collection device 4, the position of the ground micro bearing can be guided so that the micro bearing is sent to the inside of the collection frame 41 for centralized processing, avoiding the micro bearing from moving under force and affecting the subsequent grinding of a batch of micro bearings, thereby improving the grinding efficiency of the collection device for micro bearings.

[0038] When using the guide collection device 4, the collection frame 41 can be placed on the upper end of the fixing plate 51, and then the second bolt 52 can be rotated to make the second bolt 52 pass through the fixing plate 51 and be threaded to the collection frame 41. Then the collection frame 41 is fixed on one side of the workbench 1. Through the fixing component 5, the guide collection device 4 can be quickly fixed to one side of the workbench 1, which makes it convenient for the operator to use the guide collection device 4 later.
