Description

Technical Field

[0001] This utility model relates to the field of irregular valve processing technology, and in particular to an irregular valve processing fixture. Background Technology

[0002] The term "unconventional" in shaped valves refers to the fact that the ball and valve seat are not standard round. Machining fixtures are used to fix and position products during processing. In the production and processing of shaped valves (for example, drilling holes in the flanges of the three pipes of a three-way ball valve), fixtures are required for clamping.

[0003] When drilling the flanges of the three pipes of a three-way ball valve, a clamp is usually used for holding. However, if a sudden situation occurs during the drilling process and a malfunction occurs (such as the driving component (e.g., hydraulic cylinder, pneumatic cylinder, electric push rod) suddenly rises and releases the valve), the valve is prone to displacement during the drilling process, which can also lead to safety hazards. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing technology, when drilling the flanges of the three pipes of a three-way ball valve, a clamp is usually used for holding. However, if a sudden situation occurs during the drilling process and a malfunction occurs (such as the driving component of the clamp (e.g., hydraulic cylinder, pneumatic cylinder, electric push rod) suddenly rises and releases the valve clamp), the valve is prone to displacement during the drilling process, which also poses a safety hazard. Therefore, a special-shaped valve processing clamp is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A jig for processing irregularly shaped valves includes a U-shaped frame and a jig assembly for clamping the irregularly shaped valves. The jig assembly is matched with the irregularly shaped valves. The jig assembly includes a first jig and a second jig. The first jig is fixed to the bottom inner wall of the frame by bolts. A movable plate is provided above the first jig. The second jig is fixed to the bottom of the movable plate by bolts. The first jig and the second jig are at the same level. The jig assembly is provided with a prevention mechanism to prevent the second jig from suddenly rising.

[0007] To reinforce the preventative mechanism, a reinforcement mechanism is also included, which can strengthen the preventative mechanism and prevent slippage.

[0008] In one possible design, the prevention mechanism includes two sets of limiting strips, each set consisting of two strips. The top ends of the two sets of limiting strips are welded to the bottom ends of the second clamp. Both ends of the first clamp have two fourth through holes for inserting the limiting strips. One end of the limiting strip is inserted into the fourth through hole. Both ends of the first clamp have second through holes, and the fourth through holes are connected to the second through holes. The limiting strip has a first through hole, and the same fixing strip passes through the second through hole and the first through hole.

[0009] In one possible design, the reinforcement mechanism includes four insert rods, each insert rod being T-shaped, with a third through hole at both ends of the two fixing strips, and the bottom ends of the four insert rods being inserted into the four third through holes respectively.

[0010] In one possible design, a pull ring is welded to the top of the insertion rod to facilitate its extension.

[0011] In one possible design, mounting holes are provided at all four corners of the bottom of the frame to facilitate installation.

[0012] In one possible design, a driving component for driving the second clamp to press down is fixedly installed on the top of the frame. The telescopic part of the driving component passes through the top of the frame and is fixedly connected to the top of the movable plate. Two circular holes are opened on the frame, and guide rods are slidably connected to the inner walls of the circular holes. The bottom ends of the guide rods are fixedly connected to the top of the movable plate.

[0013] In this application, the irregularly shaped valve (three-way ball valve) to be processed is placed on the first clamp (the clamp assembly is matched with the three-way ball valve). The drive unit is activated, and the telescopic part of the drive unit begins to extend downward, pushing the movable plate downward. During the downward movement of the movable plate, the guide rod slides against the inner wall of the circular hole opened on the frame, playing a guiding role and ensuring that the movable plate moves smoothly without deviation. As the movable plate moves downward, the second clamp also moves downward, gradually approaching the irregularly shaped valve. When the second clamp contacts the irregularly shaped valve, the second clamp is driven to press down, so that the first clamp and the second clamp tightly clamp the irregularly shaped valve, ensuring that the irregularly shaped valve will not shift or shake during processing. When the second clamp descends to its position, the limiting strip will be inserted into the corresponding fourth through hole of the first clamp, and at the same time, the first through hole of the limiting strip and the second through hole of the first clamp will be aligned. Then, the fixing strip is removed, and the fixing strip is inserted into the second through hole and the first through hole, and the two ends of the fixing strip are aligned. The third perforation is located on both sides of one end of the first clamp. At this time, the fixing strip and a set of limiting strips form a double cross shape. The fixing strip limits the limiting strip. After the two fixing strips are inserted into the two sets of limiting strips, the insert rod is taken out and inserted into the third perforation to limit and reinforce the fixing strip and prevent it from sliding left and right. After the shaped valve is stably clamped, the operator can use the corresponding processing equipment to process the shaped valve, such as drilling and polishing the three pipe discs of the three-way ball valve. If the second clamp suddenly rises and releases the clamp on the shaped valve during the operation, it can be limited by the limiting strip and the fixing strip to prevent sudden rise. The driving component is one of the following: hydraulic cylinder (requires an external hydraulic pump station and your desired use), electric push rod (used with an external power supply), or pneumatic cylinder (used with an external air source). The specific choice can be made according to actual needs. It should be noted that the driving component needs to be controlled by an external controller and powered by an external power supply when in use.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this utility model, the special-shaped valve processing fixture, through the prevention mechanism, the limiting strip and the fixing strip in the prevention mechanism can quickly play a role. By inserting the limiting strip into the fourth through hole of the first fixture, and the fixing strip passing through the first through hole of the limiting strip and the second through hole of the first fixture, an effective limiting structure is formed to prevent the second fixture from suddenly rising. This ensures that the special-shaped valve will not shift or shake during processing, greatly improving the processing accuracy and quality. Even if the drive component fails, the limiting effect of the limiting strip and the fixing strip can ensure that the valve remains in a stable clamped state, preventing personal injury or equipment damage due to sudden release. This eliminates safety hazards in the processing process and protects the personal safety of operators and the normal operation of equipment.

[0016] In this utility model, the irregular valve processing fixture has a reinforcing mechanism. The insertion rod is T-shaped, and its bottom end is inserted into the third through hole at both ends of the fixing strip, which further reinforces the fixing strip and prevents the fixing strip from sliding left and right during processing. This design makes the entire prevention mechanism more stable and reliable. At the same time, the pull ring welded to the top of the insertion rod makes it easy for the operator to pull out the insertion rod when needed for maintenance or replacement of the fixture, which improves the ease of use of the fixture.

[0017] In this invention, the prevention mechanism can effectively prevent the second clamp from suddenly rising, thereby ensuring that the irregular valve will not shift or shake during processing, greatly improving the processing accuracy and quality. The reinforcement mechanism can reinforce the fixing strip to prevent it from sliding left and right during processing. 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] In one embodiment: Refer to Figure 1-4 A machining fixture includes: a U-shaped frame 1, a fixture assembly, a prevention mechanism, a reinforcement mechanism, and a drive component. The frame 1 provides support and a mounting base for the entire fixture. The fixture assembly is used to clamp irregularly shaped valves. The prevention mechanism and the reinforcement mechanism ensure the stability and safety of the fixture during machining. The drive component is responsible for driving the downward pressing action of the second fixture 13.

[0025] The frame 1 is U-shaped, with mounting holes 4 at each of its four bottom corners. During actual installation, bolts or other fasteners are passed through the mounting holes 4 to firmly fix the frame 1 to the workbench, ensuring that the frame 1 will not shake or shift during processing.

[0026] The clamping assembly includes a first clamp 5 and a second clamp 13, and the clamping assembly is matched with the irregularly shaped valve. The first clamp 5 is fixed to the bottom inner wall of the frame 1 by bolts to ensure that it is firmly installed.

[0027] A movable plate 3 is provided above the first clamp 5, and the second clamp 13 is fixed to the bottom of the movable plate 3 by bolts. When the driving component drives the movable plate 3 to move downward, the second clamp 13 also moves downward, cooperating with the first clamp 5 to clamp the irregular valve. The first clamp 5 and the second clamp 13 are at the same level to ensure the stability and accuracy of clamping.

[0028] The prevention mechanism includes two sets of limiting strips 6, with two limiting strips in each set. The tops of the two sets of limiting strips 6 are welded to the bottoms of both ends of the second clamp 13 to ensure a firm weld without any loosening. Both ends of the first clamp 5 have two fourth through holes for inserting the limiting strips 6. When the second clamp 13 moves downward to cooperate with the first clamp 5 to clamp the shaped valve, one end of the limiting strip 6 is inserted into the fourth through hole.

[0029] Both ends of the first clamp 5 are provided with second through holes 11, and the fourth through hole is connected to the second through holes 11. The limiting strip 6 is provided with a first through hole 10. When the limiting strip 6 is inserted into the fourth through hole, the same fixing strip 7 passes through the second through hole 11 and the first through hole 10. The fixing strip 7 limits the limiting strip 6 by passing through the second through hole 11 and the first through hole 10, preventing the second clamp 13 from suddenly rising during processing.

[0030] The reinforcement mechanism includes four T-shaped inserts 9. Each of the two fixing strips 7 has a third through hole 12 at both ends, and the bottom ends of the four inserts 9 are inserted into the four third through holes 12 respectively. After the inserts 9 are inserted into the third through holes 12, they reinforce the fixing strips 7, preventing them from slipping during processing and further enhancing the stability of the reinforcement mechanism.

[0031] A pull ring 8 is welded to the top of the insertion rod 9 to facilitate its pull-out. When maintenance or replacement of parts is required, the operator can easily pull the insertion rod 9 out of the third through hole 12 using the pull ring 8.

[0032] This application is for the field of processing irregularly shaped valves, but it can also be used in other fields applicable to this application.

[0033] In another embodiment: Reference Figure 1-4A fixture for machining irregularly shaped valves, which is used in the field of machining irregularly shaped valves.

[0034] A driving component is fixedly installed on the top of the frame 1. The driving component can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, etc., which can be selected according to actual needs and the usage environment. The telescopic part of the driving component passes through the top of the frame 1 and is fixedly connected to the top of the movable plate 3, and is used to drive the movable plate 3 to move up and down.

[0035] The frame 1 also has two circular holes, and guide rods 2 are slidably connected to the inner walls of the holes. The bottom end of the guide rods 2 is fixedly connected to the top of the movable plate 3. The guide rods 2 play a guiding role during the movement of the movable plate 3, ensuring that the movable plate 3 moves smoothly and does not deviate.

[0036] However, as is well known to those skilled in the art, the working principle and wiring method of the drive components are commonplace and are all conventional means or common knowledge, so they will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0037] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0038] 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.
