Description

Technical Field

[0001] The utility model belongs to the field of valve processing, and in particular relates to a valve deburring device. Background Art

[0002] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shutoff valves to the various valves used in extremely complex automatic control systems. Valves can be used to control the flow of various types of fluids, such as air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media.

[0003] In the prior art, most valves are produced by casting. A small number of valves after casting have burrs and other protrusions on the inner wall of the through hole. In order not to affect the subsequent use, the inner wall of the through hole is usually polished and deburred by a deburring device. However, during the deburring process of the valve, the existing deburring device cannot ensure that the grinding head is always in close contact with the inner wall of the valve port, which may lead to uneven quality of deburring the valve port. In addition, during the deburring process, the deburring head is also easy to crush the valve port. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a valve deburring device, aiming to solve the problem that the existing valve deburring device has a poor deburring effect and is easy to damage the valve port.

[0005] The utility model adopts the following technical solutions:

[0006] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0007] Further, the clamping tooling includes a tooling base slidably mounted on the workbench. A positioning opening is formed at the top of the tooling base. A pair of clamping cylinders are vertically arranged on the tooling base. A bracket is provided on the clamping cylinder. A clamping block is rotatably arranged on the bracket. The driving shaft of the clamping cylinder is rotatably connected to the tail of the clamping block. A sliding cylinder is arranged on the carriage. The driving shaft of the sliding cylinder is connected to the tooling base.

[0008] Further, a return spring is arranged above the connecting rod on the rotating rod.

[0010] Further, the deburring head is conical, and a pair of notches are formed on the deburring head.

[0011] The beneficial effects of the present utility model are as follows: When using this device to remove the burrs inside the through hole of the valve, first fix the valve to the clamping tooling, and move the clamping tooling to the processing position. Then, the lifting cylinder drives the upper sliding seat to slide downward, and the lower sliding seat drives the deburring head to slide downward synchronously. After the deburring head penetrates into the through hole of the port, the lifting cylinder continues to drive the upper sliding seat to move a short distance. During this process, all the preloading springs are compressed. At this time, the deburring head closely adheres to the inner wall of the valve port. At the same time, the driving motor drives the deburring head to rotate, and the deburring head removes the burrs and other protrusions on the inner wall of the port during rotation.

[0016] In order to make the patent purpose, technical solutions and advantages of the present utility model clearer, the following further describes the present utility model in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0017] In order to illustrate the technical solutions described in the present utility model, the following will be described through specific embodiments.

[0018] Only parts related to the embodiments of the present utility model are shown for the convenience of description.

[0019] Combined with Figures 1-4 As shown, the valve deburring device includes a workbench 1, on which a carriage 2 and a clamping tooling 3 are provided. There are two upper and lower sliding seats on the carriage 2. For example, Figure 1 the upper sliding seat is marked as 41 and the lower sliding seat is marked as 42. A pair of sliding rods 5 penetrate through the upper sliding seat 41, and the bottom of the sliding rod 5 is fixed to the lower sliding seat 42. A pre-tightening spring 6 is provided between the two sliding seats on the sliding rod 5, and a retaining ring 20 is provided above the upper sliding seat on the sliding rod. A deburring head 7 is rotatably provided on the lower sliding seat 42. A connecting rod 8 is provided at the top of the deburring head 7, and a through chute 9 is opened on the connecting rod 8. A driving motor 18 is provided on the upper sliding seat 41. The driving shaft of the driving motor 18 passes through the upper sliding seat and is provided with a rotating rod 11. The rotating rod 11 penetrates into the connecting rod 8. A limiting screw 10 penetrates into one side of the chute 9. The limiting screw 10 passes through the connecting rod 8 and passes out from the other side of the chute 9 and then is screwed into a limiting nut 101, and the limiting nut is not tightened. A lifting cylinder 12 is provided at the top of the carriage 2, and the driving shaft of the lifting cylinder 12 is connected to the upper carriage 41.

[0020] In the prior art, most valves are produced by casting. Valves generally have two inlet and outlet ports. For a small number of valves after casting, there will be burrs and other protrusions on the inner wall of the through holes of the ports. In order not to affect subsequent use, the inner wall of the through holes can be polished and deburred by using this deburring device.

[0021] When using this device to remove the burrs inside the through holes of the valve, first place the valve on the clamping tooling according to the requirements for fixation. The clamping tooling moves to the processing position, and one port of the valve faces the deburring head. Immediately afterwards, the lifting cylinder drives the upper sliding seat to slide downward, and the lower sliding seat drives the deburring head to slide downward synchronously. After the deburring head penetrates into the through hole of the port, the lifting cylinder continues to drive the upper sliding seat to move a small distance. During this process, all the pre-tightening springs are compressed, and the deburring head closely adheres to the inner wall of the valve port. At the same time, the driving motor drives the deburring head to rotate, and the deburring head removes burrs and other protrusions on the inner wall of the port during rotation.

[0022] Such as Figure 2 , the deburring head 7 is conical, and a pair of notches 13 are formed on the deburring head. The design structure of the deburring head facilitates its better penetration into the inner wall of the valve port. And the effect of the deburring head is better.

[0023] Such as Figure 3, a return spring 17 is provided above the connecting rod 8 on the rotating rod 11, and a stopper 19 is provided above the return spring on the rotating rod. When the lifting motor drives the upper sliding seat to move downward, at this time the rotating rod moves downward along the inner wall of the connecting rod, the return spring is compressed, and the limit screw moves downward in the chute. The limit rod plays a role of guiding and limiting, so that the rotating rod is always located inside the connecting rod. When the driving motor drives the rotating rod to rotate, under the action of the limit screw, the connecting rod rotates synchronously, and the deburring head performs the deburring action.

[0024] After the deburring of the valve is completed, the driving motor stops working, and the lifting cylinder drives the upper sliding seat to move upward. The pre-tightening spring recovers its deformation and under its action, the lower sliding seat resets. At the same time, during the upward movement of the upper sliding seat, the return spring also recovers its deformation. Under the action of the return spring, the rotating rod moves upward along the inner wall of the connecting rod and resets. Finally, the clamping tooling is loosened. If there are burrs on the inner wall of the other port of the valve, the valve is fixed to the clamping tooling according to the installation requirements. At this time, this port is arranged facing the deburring head.

[0025] The lower sliding seat 42 is provided with a limit post 14 upward, and a limit head 15 is provided at the top of the limit post. When the lifting cylinder drives the upper sliding seat to move downward until the deburring head penetrates into the inner wall of the valve port, the upper sliding seat continues to move downward a small distance, the pre-tightening spring is compressed, and the deburring head is closely attached to the inner wall of the valve port. At this time, the limit head abuts against the upper sliding seat, preventing the upper sliding seat from continuing to move downward a small distance and the valve from being damaged by the deburring head.

[0026] Further, as a preferred structure, as Figure 4 , the clamping tooling 3 includes a tooling seat 31 slidably installed on the workbench 1. A positioning port 32 is opened at the top of the tooling seat 31. A pair of clamping cylinders 33 are vertically provided on the tooling seat 31. A bracket 34 is provided on the clamping cylinder 33. A clamping block 35 is rotatably provided on the bracket 34. The driving shaft of the clamping cylinder 33 is rotatably connected to the tail of the clamping block 35. A sliding cylinder 36 is provided on the carriage 2. The driving shaft of the sliding cylinder 36 is connected to the tooling seat 31.

[0027] When deburring the valve, first the tooling seat is located at the loading position. One port of the valve is inserted into the positioning port according to the requirements. At this time, the valve is placed flat on the tooling seat, and the other port is arranged upward. Then the two clamping cylinders drive the tails of the clamping blocks to move upward simultaneously until the two clamping blocks press the valve seat on the valve. Finally, the sliding cylinder drives the tooling seat to move towards the sliding seat to the processing position and waits for processing.

[0028] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the present utility model.
