Description

Technical Field

[0001] The utility model relates to the technical field of grinding and polishing, in particular to a grinding device for polishing in the production of globe valves. Background Technique

[0002] A globe valve, also known as a stop valve, belongs to a forced-sealing valve. Therefore, when the valve is closed, pressure must be applied to the valve flap to force the sealing surface not to leak. During the use of the globe valve, it is usually connected to other pipe fittings by using the flange at the end. Therefore, in the production process, higher requirements are placed on the flatness of the end.

[0003] At present, when the grinding equipment fixes the globe valve, it needs to be manually fixed by workers, resulting in a large workload for the workers. Even if the equipment is used for fixing, it is impossible to fix valves of different sizes, and the practicability is poor. Moreover, after one end is ground, it is necessary to repeat the operation to re-fix and grind the other end, and the overall grinding efficiency is low. Content of the Utility Model

[0004] In view of the above situation, to make up for the above-mentioned existing defects, the utility model provides a grinding device for polishing in the production of globe valves.

[0005] The utility model provides the following technical solutions: A grinding device for polishing in the production of globe valves proposed by the utility model includes a support frame, a grinding assembly is arranged on the support frame, a driving assembly is arranged at the lower end of the support frame, and a direction-changing assembly is arranged on the driving assembly; the driving assembly includes a support plate, there are two groups of support plates, the support plates are arranged on the support frame, a rotating shaft is rotatably arranged between the support plates, a driving motor is arranged on the support plate, the output end of the driving motor is connected to the rotating shaft, a rotating cylinder is sleeved on the rotating shaft, vertical plates are symmetrically arranged on the rotating cylinder, there are multiple groups of vertical plates, and a direction-changing assembly is arranged between the vertical plates.

[0006] Furthermore, the direction-changing component includes an auxiliary support shaft, which is arranged on the opposite surface of one side in the vertical plate. A linkage rotating shaft is rotatably arranged on the other group in the vertical plate away from the auxiliary support shaft. A rotating plate is sleeved on the auxiliary support shaft. There are two groups of the rotating plates. The other group of the rotating plates is sleeved on the linkage rotating shaft. The rotating plates are arranged between the vertical plates. Fixing parts are arranged at both ends of the rotating plate away from the rotating cylinder. A locking part is arranged on the side of the rotating plate away from the fixing part. The other end of the locking part is arranged on the rotating cylinder. A main shaft is rotatably arranged on one side of the support plate away from the driving motor. The main shaft and the rotating shaft are on the same line. A driving wheel is sleeved on the main shaft. A linkage wheel is sleeved on the linkage rotating shaft. The linkage wheel is meshed with the driving wheel. The flange ends at both ends of the globe valve are clamped to both sides of the fixing part by using the fixing part, and the direction-changing component is fixed by using the locking part to prevent the rotating plate from rotating. The driving motor is started, and the driving motor drives the rotating shaft to rotate. The rotating shaft drives the rotating cylinder to rotate. The rotating cylinder drives the vertical plate to rotate. The vertical plate drives the direction-changing component to rotate. The direction-changing component drives the globe valve to rotate through the fixing part, so that the globe valve is rotated under the grinding component for grinding. After one end of a globe valve is ground, as long as the driving motor is used, different globe valves can be rotated under the grinding component in turn. After all the ends of all the globe valves on the device are ground, the locking part is opened, and the driving wheel is rotated. The driving wheel drives the linkage wheel to rotate. The connecting wheel cooperates with the auxiliary support shaft to drive the rotating plate to rotate, so that the other end of the globe valve fixed on the rotating plate is rotated under the grinding component, and the above operation using the driving motor is repeated to grind the other end of the globe valve in turn.

[0007] Among them, the fixing part includes a fixing plate, which is symmetrically arranged at the end of the rotating plate and connected to both ends of the rotating plate. Through holes are arranged on the fixing plate. Activity grooves are symmetrically arranged on the fixing plate and on both sides of the through holes. Fixing springs are arranged in the activity grooves. The fixing springs are connected with clamping plates. One end of the clamping plate is movably arranged in the activity groove and the other end is arranged in the through hole. When fixing the globe valve, the clamping plate is pushed towards the direction close to the activity groove, so that the clamping plate is retracted into the activity groove. At this time, the fixing spring is in a compressed state, and the through hole is exposed. The two ends of the globe valve are passed through the through hole, and the clamping plate is released. Under the elastic force of the fixing spring, the clamping plate moves away from the activity groove to clamp the end of the globe valve, playing a role in supporting and fixing the globe valve during the grinding process.

[0008] Preferably, the locking member includes a groove provided on the side of the rotating plate away from the fixing plate. The groove is provided at the end of the rotating plate. A connecting spring is provided in the groove. The connecting spring is connected to a clamping block made of magnetic material. The rotating cylinder is evenly provided with clamping grooves, and the rotating cylinder is evenly provided with energized coils. The energized coils are provided on one side of the clamping grooves. After the stop valve is fixed by the fixing member, the energized coils are energized, and a magnetic field is generated around the energized coils, generating an attractive force on the clamping block, causing the clamping block to move away from the groove and move into the clamping groove, thereby realizing the fixing process of the rotating plate and preventing the rotating plate from rotating during the grinding of the stop valve and affecting the grinding effect.

[0009] Further, the grinding assembly includes a telescopic rod provided on the support frame. The output end of the telescopic rod is provided with a grinding motor, and the output end of the grinding motor is provided with a grinding disc. After the end of the stop valve is moved under the grinding disc, the telescopic rod is started. The telescopic rod drives the grinding disc to move downward through the grinding motor until the grinding disc contacts the stop valve, and then the grinding motor is started. The grinding motor drives the grinding disc to rotate, thereby realizing the grinding process of the end face of the stop valve.

[0010] Among them, the driving motor is a servo motor, which has higher precision during use and improves the practicability of the device.

[0011] A polishing and grinding device for the production of stop valves proposed by the present invention with the above structure has the following beneficial effects:

[0012] 1. Through the setting of the driving component, the process of automatically grinding multiple workpieces is realized, reducing the burden on workers and improving the grinding efficiency.

[0013] 2. The setting of the direction-changing component realizes the fixation of multiple workpieces and also facilitates the adjustment of the grinding position of the stop valve, eliminating the process of repeated fixation operations.

[0014] 3. Due to the setting of the fixing member, stop valves of different sizes can be fixed, enhancing the practicability of the device and increasing the utilization rate of the device.

[0015] 4. The locking member is used to realize the fixing process of the rotating plate, preventing the rotating plate from rotating during the grinding of the stop valve and affecting the grinding effect. BRIEF DESCRIPTION OF THE DRAWINGS
