Description

Technical Field

[0001] The invention belongs to the technical field of ball valve processing, and in particular relates to a ball valve processing device. Background Art

[0002] The ball valve was introduced in the 1950s. With the rapid development of science and technology, the continuous improvement of production technology and product structure, it has rapidly developed into a major valve type in just 40 years. The ball valve is a commonly used fluid control valve with a simple structure, easy operation, and the ability to quickly switch and cut off the fluid. In the ball valve structure, the ball valve body is an important part of the ball valve. In the prior art, the ball valve body 5 (such as Figure 8 As shown in the figure, there are valve chamber 51, valve seat groove 52, flow passage 53, valve stem hole 54, packing blind hole 55 and screw hole 56 in the ball valve body 5. The production quality of the ball valve body 5 seriously affects the working stability of the ball valve. Therefore, ensuring the production quality of the ball valve body 5 is the top priority of ball valve production. However, the following problems still exist in the processing process:

[0003] 1. During the production of the ball valve body 5, the inside thereof needs to be machined, so that burrs will be generated between the valve cavity 51 and the valve seat groove 52, and between the valve seat groove 52 and the flow passage 53 in the ball valve body 5. The burrs will affect the rotation of the valve ball when the ball valve is used. Therefore, the valve cavity 51, the valve seat groove 52 and the flow passage 53 need to be polished and deburred after machining. At present, deburring is generally performed by workers holding a scraper. This method is not only inefficient, but also easy to miss, which will affect the production quality of the ball valve body 5.

[0004] 2. When the ball valve body 5 is produced, a valve stem hole 54 needs to be processed on the ball valve body 5, and a packing blind hole 55 needs to be processed at the outlet of the valve stem hole 54, so that burrs will be left on both sides of the valve stem hole 54.

[0038] Combination Figure 1 , Figure 5 As shown, in this embodiment, a countersunk hole is provided on the lifting frame 21, and a steel ball 61 and a positioning spring 62 are provided in the countersunk hole. The positioning spring 62 drives the steel ball 61 to move away from the countersunk hole.

[0039] Combination Figure 1 , Figure 5 As shown, in this embodiment, when the steel ball 61 is located in the positioning groove 221, the deburring mechanism 2 is in a moving state; when the steel ball 61 exits the positioning groove 221, the deburring mechanism 2 is in a rotating state.

[0040] The process and principle of this ball valve processing equipment for internal polishing and deburring of the ball valve body are as follows:

[0041] Process 1: Loading:

[0042] When the present invention is needed to perform deburring and internal polishing on the ball valve body 5, the ball valve body 5 needs to be placed on the base 1 first, with the valve stem hole 54 on the ball valve body 5 facing right, and the screw pin 11 is inserted into the screw hole 56 to position the ball valve body 5 and complete the loading.

[0043] Process 2: Valve body clamping:

[0044] When the loading is completed, the control clamp electric push rod 33 is extended to drive the clamp plate 31 to move downward, and then drive the jaws 32 to move downward. Since the lower end of the jaws 32 is hinged to the clamp plate 31, the base groove pin 13 is slidably set in the vertical groove 321 and the inclined groove 322, so that when the jaws 32 move downward, the base groove pin 13 slides from the inclined groove 322 to the vertical groove 321, and then the jaws 32 rotate toward the middle during the downward movement, thereby clamping the ball valve body 5, completing the clamping work of the ball valve body 5.

[0045] Process 3: Polishing and deburring of valve body:

[0046] When the ball valve body 5 is clamped, the lifting electric push rod 4 is controlled to retract, driving the deburring mechanism 2 to enter the ball valve body 5. When the bottom end of the deburring grinder 25 is flush with the lower plane of the flow channel 53, and the deburring shaft 26 is aligned with the valve stem hole 54, the lifting electric push rod 4 is controlled to stop. At this time, the steel ball 61 enters the positioning groove 221 under the action of the positioning spring 62, and the deburring mechanism 2 is in a moving state. Then the driving motor 28 is started to drive the worm 231 to rotate forward. Due to the worm wheel 232 and the worm 231 The worm gear 232 is meshed with each other, thereby driving the worm gear 232 to rotate clockwise, driving the transmission plate 233 to rotate accordingly. Since one end of the transmission rod 234 is hinged to the transmission plate 233, and the other end is hinged to the deburring tool 25, the deburring tool 25 is driven to slide leftward along the burring track 222. When the deburring tool 25 reaches the leftmost end of the burring track 222 and fits with the left end surface of the burring track 222, the abrasive 251 on the deburring tool 25 is tightly attached to the inner walls of the valve cavity 51, the valve seat groove 52 and the flow passage 53 (such as Figure 1 As shown), the driving motor 28 is controlled to continue to rotate forward. Since the deburring grinder 25 cannot continue to move leftward along the burr track 222, the worm wheel 232 and the worm 231 are relatively stationary, thereby driving the deburring rack 22 to rotate, so that the steel ball 61 overcomes the positioning spring 62 and exits the positioning groove 221. The deburring mechanism 2 switches to a rotating state, driving the deburring grinder 25 to rotate around the axis of the ball valve body 5, so that the abrasive 251 can grind the inner walls of the valve cavity 51, the valve seat groove 52 and the flow passage 53, and at the same time, the burrs at the connection between the valve cavity 51 and the valve seat groove 52, and the connection between the valve seat groove 52 and the flow passage 53 can be removed, thereby completing the polishing and deburring of the ball valve body 5.

[0047] Process 4: Deburring both ends of the valve stem hole:

[0048] When the polishing and deburring of the ball valve body 5 are completed, the driving motor 28 is controlled to drive the deburring frame 22 to stop, so that the positioning groove 221 and the steel ball 61 are aligned, and the steel ball 61 enters the positioning groove 221 for positioning under the action of the positioning spring 62, so that the deburring shaft 26 is aligned with the valve stem hole 54 again, and the deburring mechanism 2 returns to the moving state, and then the driving motor 28 is controlled to drive the worm 231 to reverse, drive the worm wheel 232 to rotate counterclockwise, and then drive the deburring grinder 25 to move rightward through the transmission rod 234, drive the deburring shaft 26 to move rightward, and because the worm 231 and the first The bevel gear 241 is coaxial and fixedly connected, the first bevel gear 241 and the second bevel gear 242 are meshed, the second bevel gear 242 and the first belt pulley 243 are coaxial and fixedly connected, thereby driving the first belt pulley 243 to rotate. Since the first belt pulley 243 and the second belt pulley 244 cooperate through the belt 245, and the second belt pulley 244 cooperates with the flat key of the deburring shaft 26, the deburring shaft 26 is driven to rotate in the process of moving to the left, so that the burr scraper 271 moves toward the valve stem hole 54. When the right blade of the burr scraper 271 comes to the intersection of the valve stem hole 54 and the valve cavity 51 When the right blade touches the ball valve body 5, the ball valve body 5 pushes the burr scraper 271 to overcome the reed 272 and shrink into the deburring shaft 26 through the right blade tilted to the left, so that the burr scraper 271 can follow the deburring shaft 26 to pass through the valve stem hole 54 and enter the packing blind hole 55. When the burr scraper 271 enters the packing blind hole 55, the reed 272 pushes the burr scraper 271 to extend, and then controls the drive motor 28 to rotate forward. Since the deburring mechanism 2 is in a moving state, the deburring is performed. The grinding tool 25 drives the deburring shaft 26 to move to the left, and drives the deburring shaft 26 to rotate at the same time. When the left blade on the burr scraper 271 comes to the intersection of the packing blind hole 55 and the valve stem hole 54, the left blade will scrape off the burrs there by rotating. When the left blade contacts the ball valve body 5, the ball valve body 5 will push the burr scraper 271 to overcome the reed 272 and shrink into the deburring shaft 26 through the left blade tilted to the right, so that the burr scraper 271 can follow the deburring shaft 26 to pass through the valve stem hole 54 and return to the valve cavity 51, completing the deburring work at both ends of the valve stem hole 54.

[0049] Process 5: Loosening and unloading the valve body:

[0050] When the deburring work at both ends of the valve stem hole 54 is completed, the lifting electric push rod 4 is controlled to extend, driving the deburring mechanism 2 to withdraw from the ball valve body 5, and then the clamp electric push rod 33 is controlled to contract, driving the clamp plate 31 to move upward, and then driving the clamping claw 32 to move upward, so that the base groove pin 13 slides from the vertical groove 321 to the inclined groove 322, and then the clamping claw 32 rotates outward during the upward movement, thereby loosening the ball valve body 5, and then the ball valve body 5 is removed by the worker to complete the unloading.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
