Description

Technical Field

[0001] This utility model relates to the field of positioning fixtures for valve processing, specifically a positioning fixture for valve processing that facilitates position adjustment. Background Technology

[0002] Valve machining positioning fixtures are process equipment used to precisely position and fix valve components during valve machining. Their purpose is to ensure the machining accuracy and quality of valves and improve production efficiency. However, existing valve machining positioning fixtures have some shortcomings, such as: A positioning fixture for machining electric valve actuators, application number CN202122895323.X, solves the problem that existing positioning fixtures for electric valve actuators can only fix actuators of one shape, and can only position electric valve actuators of a fixed shape, making it inconvenient to clamp electric valve actuators of different shapes. However, in actual use, this device may cause the valve to be difficult to adjust when clamping, which may lead to the need for manual adjustment of the valve during the machining process. Therefore, we propose a positioning fixture for valve processing that facilitates orientation adjustment in order to solve the problems mentioned above. Utility Model Content

[0003] The purpose of this utility model is to provide a positioning fixture for valve processing that is easy to adjust, so as to solve the problem mentioned in the background art that the positioning fixtures for valve processing on the market may cause valves to be difficult to adjust when clamping and adjusting.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for valve processing that facilitates orientation adjustment, comprising a main body of the device and a clamping plate disposed on the top of the main body of the device; The main body of the device is equipped with a drive mechanism, and the top of the drive mechanism is equipped with a clamping mechanism. The clamping mechanism includes a fixed seat, the top of the fixed seat is equipped with a first buffer damper, the other end of the first buffer damper is connected to a first clamping roller, and the right end of the fixed seat is connected to a fixed plate. The top of the fixed plate is equipped with a rotating seat, and the top of the rotating seat is rotatably connected to the clamping plate. The main body of the device is provided with another set of fixed seats on the top, and a second buffer damper is installed on the top of the fixed seats. The left end of the second buffer damper is connected to a second clamping roller, and the second clamping roller is horizontal with the first clamping roller.

[0005] The clamping mechanism is moved by the drive mechanism, which allows the valve on the top of the fixed plate to be clamped and fixed by the first and second clamping rollers on the outside. This causes some of the first or second buffer damping to contract, generating pressure on the first or second clamping rollers for clamping. When the position of the valve is adjusted, the degree of contraction of the first or second buffer damping will change, allowing the first and second clamping rollers to clamp the valve better, thus increasing the convenience of the equipment when adjusting the valve processing angle.

[0006] As a preferred technical solution of this utility model, the main body of the device is fixedly connected to the drive mechanism, and the drive mechanism includes a first motor, and the drive end of the first motor is connected to a first sprocket, a chain is engaged on the outside of the first sprocket, and a second sprocket is engaged on the outside of the chain.

[0007] The above technical solution enables the drive mechanism to move more stably when driving the clamping mechanism, thereby increasing the stability of the equipment during operation and making the equipment more stable when clamping the valve.

[0008] As a preferred technical solution of this utility model, both the first sprocket and the second sprocket are provided with threaded shafts at their right ends, and threaded sleeves are provided on the outside of the threaded shafts, and the top of the threaded sleeves is fixedly connected to the clamping mechanism.

[0009] The above technical solution enables the threaded shaft to rotate, which in turn drives the threaded sleeve to move smoothly along the axial direction. This allows for precise adjustment of the position of the clamping mechanism. The rigid fixation between the threaded sleeve and the clamping mechanism ensures that the clamping mechanism moves synchronously with the threaded sleeve, preventing clamping offset caused by loose connection.

[0010] As a preferred technical solution of this utility model, the main body of the device is provided with a rotating mechanism, and the rotating mechanism includes a second motor. The driving end of the second motor is connected to a grooved rod. A bevel gear set is slidably connected to the outside of the grooved rod. A rotating shaft is installed on the top of the bevel gear set. The rotating shaft passes through the fixed plate and is fixedly connected to the rotating seat.

[0011] The above technical solution enables the bevel gear set to convert the horizontal rotation of the second motor into the vertical rotation of the rotating shaft, which drives the rotating seat and clamping plate to rotate, thereby increasing the stability of the device when driving the rotating seat and clamping plate to rotate.

[0012] As a preferred technical solution of this utility model, a threaded rod is threadedly connected to the outer side of the fixing plate, and the threaded rod is rotatably connected to the fixing seat in the clamping mechanism.

[0013] The above technical solution enables the threaded rod to adjust the distance between the fixed plate and the fixed seat through threaded transmission, adapting to the clamping requirements of valves with different diameters. This makes the device more secure when clamping valves of different sizes and shapes, thereby increasing the device's clamping stability.

[0014] As a preferred technical solution of this utility model, a torsion shaft is provided on the outer side of the threaded rod, and a clamping groove is provided on the top of the clamping plate, and the clamping groove can fit and fix with the bottom of the valve body.

[0015] The above technical solution enables the clamping groove to fit and fix the bottom of the valve body, which can limit the bottom of the valve, prevent longitudinal displacement during valve processing, and prevent scratches on the valve surface caused by rigid clamping, thus adapting to the processing requirements of valves made of different materials.

[0016] As a preferred embodiment of this utility model, the first clamping roller and the second clamping roller are located at the top of the clamping plate, and the bottom of the fixing plate is rotatably connected to the bevel gear set through a bearing seat.

[0017] The above technical solution enables the first clamping roller and the second clamping roller to form a bidirectional horizontal clamping on the top of the clamping plate, making it more convenient to adjust the valve angle.

[0018] Compared with the prior art, the beneficial effects of this utility model are: by driving the clamping mechanism to move through the drive mechanism, the valve on the top of the fixed plate can be clamped and fixed by the first and second clamping rollers on the outside, thereby causing some of the first or second buffer damping to contract, generating pressure on the first or second clamping rollers for clamping. When the position of the valve is adjusted, the degree of contraction of the first or second buffer damping will change, thereby allowing the first and second clamping rollers to clamp the valve better, thus increasing the convenience of the equipment when adjusting the valve processing angle. Furthermore, by setting up the threaded shaft and the threaded sleeve, the threaded shaft can rotate and drive the threaded sleeve to move smoothly along the axial direction, which can accurately adjust the position of the clamping mechanism. The rigid fixation of the threaded sleeve and the clamping mechanism can ensure that the clamping mechanism moves synchronously with the threaded sleeve, avoiding clamping deviation caused by loose connection. Furthermore, by setting up a rotating mechanism, the bevel gear set can convert the horizontal rotation of the second motor into the vertical rotation of the rotating shaft, driving the rotating seat and clamping plate to rotate, thereby increasing the stability of the device when driving the rotating seat and clamping plate to rotate.

[0022] To address the issue that existing positioning fixtures used in valve processing may cause difficulties in valve adjustment during clamping and adjustment, the following solution is disclosed. Please refer to [link / reference]. Figures 1-6 This utility model provides a technical solution: a positioning fixture for valve processing that is easy to adjust the orientation, including a device body 1 and a clamping plate 12 provided on the top of the device body 1; The main body 1 of the device is provided with a drive mechanism, and the top of the drive mechanism is provided with a clamping mechanism. The clamping mechanism includes a fixed seat, the top of the fixed seat is provided with a first buffer damper 8, the other end of the first buffer damper 8 is connected to a first clamping roller 9, and the right end of the fixed seat is connected to a fixed plate 10. The top of the fixed plate 10 is provided with a rotating seat 11, and the top of the rotating seat 11 is rotatably connected to a clamping plate 12. The main body 1 of the device is provided with another set of fixed seats at the top, and a second buffer damper 19 is installed on the top of the fixed seats. The second buffer damper 19 is connected to a second clamping roller 20 at the left end. The second clamping roller 20 and the first clamping roller 9 are in a horizontal state. The main body 1 of the device is fixedly connected to the drive mechanism, and the drive mechanism includes a first motor 2, and the drive end of the first motor 2 is connected to a first sprocket 3. A chain 4 is engaged on the outside of the first sprocket 3, and a second sprocket 5 is engaged on the outside of the chain 4. The right end of the first sprocket 3 and the second sprocket 5 are both provided with a threaded shaft 6, and a threaded sleeve 7 is provided on the outside of the threaded shaft 6. The top of the threaded sleeve 7 is fixedly connected to the clamping mechanism. The main body 1 of the device is equipped with a rotating mechanism, which includes a second motor 15. The driving end of the second motor 15 is connected to a grooved rod 16. A bevel gear set 17 is slidably connected to the outside of the grooved rod 16. A rotating shaft 18 is installed on the top of the bevel gear set 17. The rotating shaft 18 passes through the fixed plate 10 and is fixedly connected to the rotating seat 11. The outer side of the fixed plate 10 is threaded with a threaded rod 14, and the threaded rod 14 is rotatably connected to the fixed seat in the clamping mechanism; the outer side of the threaded rod 14 is provided with a torsion shaft, and the top of the clamping plate 12 is provided with a clamping groove 13, and the clamping groove 13 can fit and fix to the bottom of the valve body; the first clamping roller 9 and the second clamping roller 20 are located on the top of the clamping plate 12, and the bottom of the fixed plate 10 is rotatably connected to the bevel gear set 17 through a bearing seat.

[0023] Working principle: When using this valve processing positioning fixture which is easy to adjust the position, it is first connected to an external power source. Then, the drive mechanism drives the clamping mechanism to move to the designated position, so that the clamping plate 12 can fix the valve workpiece at the bottom through the clamping groove 13. At the same time, when the clamping plate 12 moves the valve workpiece between the first clamping roller 9 and the second clamping roller 20, when the first clamping roller 9 and the second clamping roller 20 contact the valve surface, the first buffer damper 8 and the second buffer damper 19 are squeezed and contracted, generating a uniform clamping force. The rolling friction characteristics reduce damage to the valve surface, and at the same time, it adapts to the slight unevenness of the valve surface to ensure that the clamping is not loose. When the drive mechanism is running, the first motor 2 drives the first sprocket 3 to rotate, which is transmitted to the second sprocket 5 through the chain 4. The first sprocket 3 and the second sprocket 5 will synchronously drive the right end threaded shaft 6 to rotate, and the threaded sleeve 7 on the outside of the threaded shaft 6 moves axially, driving the clamping mechanism to move, so that the first clamping roller 9 and the second clamping roller 20 can clamp and fit the valve workpiece. When the rotating mechanism is running, the second motor 15 drives the grooved rod 16 to rotate. The grooved rod 16 drives the bevel gear set 17 to rotate through the outer sliding groove, converting the horizontal rotation into the vertical rotation of the rotating shaft 18. The rotating shaft 18 passes through the fixed plate 10 and is fixedly connected to the rotating seat 11, driving the clamping plate 12 to rotate synchronously with the valve.
