Description

Technical Field

[0001] This utility model relates to the field of valve core manufacturing technology, and specifically discloses an end face polishing device. Background Technology

[0002] The valve core is mainly used in the valve body. It is the valve component that enables the valve body to perform basic functions such as directional control, pressure control, or flow control through its movement.

Although existing valve core polishing and grinding equipment can polish multiple valve cores simultaneously, it cannot clamp each valve core synchronously, wasting a lot of time and resulting in low work efficiency. Furthermore, each grinding section of the existing valve core polishing and grinding equipment requires a separate drive, which is costly.

[0003] To address the aforementioned issues, we provide an end-face polishing apparatus. Utility Model Content

[0031] Example

[0032] To address the problem that existing polishing and grinding devices used for polishing valve core end faces cannot synchronously clamp all valve cores, resulting in wasted time and low work efficiency, reference is made to... Figures 1-3 As shown, this application discloses an end face polishing device, including a machine base 10, a telescopic base 20, a linkage clamping mechanism 30, and a linkage polishing mechanism 40.

[0033] The telescopic base 20 includes a first telescopic drive unit 21 arranged along a first direction on the machine base 10 and a seat 22 connected to the first telescopic drive unit 21.

[0034] The linkage clamping mechanism 30 includes several clamps 31 arranged along the second direction on the base 22 and a second telescopic drive unit 32 arranged on one side of the clamps 31 along the second direction on the base 22. The clamps 31 include a fixed semicircular ring 311 fixed on the base 22 and a movable semicircular ring 312 hinged to one side of the fixed semicircular ring 311. The telescopic part of the second telescopic drive unit 32 is connected to the movable semicircular rings 312.

[0035] The linkage polishing mechanism 40 includes a lifting drive unit 41 on one side of the first direction, a plurality of polishing units 42 disposed on the drive part of the lifting drive unit 41 and mutually driven, and a rotation drive unit 43 disposed on one side of the lifting drive unit 41 in the second direction and connected to one of the polishing units 42 thereon.

[0036] In practice, the operator first places several valve cores between the fixed semicircular rings 311 and movable semicircular rings 312 of several clamps 31, and controls the second telescopic drive unit 32 to drive the movable semicircular rings 312 to move synchronously and cooperate with the fixed semicircular rings 311 to fix the valve cores synchronously in the clamps 31. After that, the first telescopic drive unit 21 drives the seat 22 to move to the bottom of the linkage polishing mechanism 40, and then controls the lifting drive unit 41 to drive the polishing unit 42 to descend and contact the end face of the valve core. The operator then controls the rotation drive unit 43 to drive the polishing unit 42 to rotate synchronously, so that the end face of the valve cores can be polished.

[0037] In one specific embodiment, the first telescopic drive unit 21 of this application includes a first electric lead screw slide 211 arranged in the middle of the machine tool 10 along a first direction and first linear guide rails 212 arranged on both sides of the machine tool 10 along the first direction on both sides of the first electric lead screw slide 211. The seat body 22 is slidably connected to the two first linear guide rails 212 and connected to the first electric lead screw slide 211. Under the drive of the first electric lead screw slide 211, the seat body 22 will move on the two first linear guide rails 212. In this way, the valve core clamped on the seat body 22 can be located below the linkage polishing mechanism 40.

[0038] To facilitate the pre-fixing of the valve core, this application provides several positioning slots 221 along the second direction on the upper surface of the seat 22. Several clamps 31 are arranged in sequence corresponding to several positioning slots 221. In specific implementation, the operator can pre-insert the valve core into the positioning slot. In this way, the valve core can be fixed by the cooperation of the movable semicircular ring 312 and the fixed semicircular ring 311.

[0039] In one specific embodiment, the second telescopic drive unit 32 of this application includes a cylinder 321 and several connecting rods 322. The cylinder 321 is disposed above the seat 22 along the second direction. One end of each of the connecting rods 322 is movably connected to the piston rod of the cylinder 321, and the other end is connected to several movable semi-circular rings 312 respectively. Under the drive of the cylinder 321, the several connecting rods 322 will drive the movable semi-circular rings 312 to slide, thereby cooperating with the fixed semi-circular rings 311 to fix the valve core.

[0040] In order to achieve a hinge connection between the fixed semicircular ring 311 and the movable semicircular ring 312, this application provides an upper connecting block 3111 on the side of the fixed semicircular ring 311 away from the second telescopic drive unit 32 and facing the movable semicircular ring 312. The movable semicircular ring 312 is provided with a lower connecting block 3121 on the side of the movable semicircular ring 312 away from the second telescopic drive unit 32 and facing the fixed semicircular ring 311. The upper connecting block 3111 is connected to the lower connecting block 3121 via a rotating shaft 313. Based on this structure, the movable semicircular ring 312 can rotate and separate from the fixed semicircular ring 311 or move closer to it under the drive of the cylinder 321, thereby realizing the release or clamping of the valve core.

[0041] In addition, this application also provides several sliding grooves 222 on the base 22 that correspond to the movement trajectory of the movable semicircular ring 312. The bottom of each of the movable semicircular rings 312 is provided with a slider that slides in the several sliding grooves 222. In this way, it can be ensured that the movable semicircular ring 312 can move smoothly under the drive of the cylinder 321, which has strong practicality. Moreover, the movable semicircular ring 312 is provided with a protruding block 3122 on the side away from the lower connecting block 3121. The protruding block 3122 is hinged to the corresponding connecting rod 322, which can facilitate a better connection between the connecting rod 322 and the movable semicircular ring 312.

[0042] In one specific embodiment, the lifting drive unit 41 of this application includes a stand 411, a second electric lead screw slide 412 arranged in the middle of the stand 411 along a third direction, second linear guide rails 413 arranged on the stand 411 along a third direction on both sides of the second electric lead screw slide 412, and a lifting slide 414 slidably connected to the two second guide rails and connected to the second electric lead screw slide 412. The polishing unit 42 of this application includes a bearing seat 421 disposed on the lifting slide 414, a drive shaft 422 passing through the bearing seat 421, and a polishing wheel 423 disposed at the bottom of the drive shaft 422. The gears 424 located on the top of the drive shaft 422 and the gears 424 of the several polishing units 42 are meshed and connected to each other. The rotation drive unit 43 includes a power motor 431. The output shaft of the power motor 431 is connected to a drive shaft 422. Under the drive of the second electric screw slide 412, the lifting slide 414 can be raised and lowered on two linear guide rails until the polishing wheel 423 contacts the end face of the valve core. After that, the power motor 431 drives the drive shaft 422 to rotate. With the cooperation of the gears 424, the polishing wheels 423 will rotate together to polish the end faces of multiple valve cores simultaneously.
