Description

Technical Field

[0001] This invention relates to the field of PVC sleeve processing technology, specifically to a cutting and grinding device for PVC sleeve processing. Background Technology

[0002] PVC (polyvinyl chloride) conduits are widely used in many fields such as construction, electrical engineering, and communications due to their advantages such as strong corrosion resistance, excellent insulation performance, and low cost. In practical applications, PVC conduits often need to be cut to obtain the appropriate length to meet different usage requirements.

[0003] The existing PVC sleeves still have the following shortcomings after cutting:

[0004] 1. The cut surface of PVC conduit after cutting is often rough and uneven. When PVC conduit is used for wiring, the rough cut surface may scratch the insulation layer of the wire, which may lead to safety hazards such as leakage. In the installation of electrical equipment, the uneven cut surface will affect the tightness of the connection between the conduit and other components, and reduce the stability of the entire system.

[0005] 2. After grinding the cut surface of the PVC sleeve, burrs are likely to appear on the ground end face of the PVC sleeve, so the cut surface of the PVC sleeve needs to be treated a second time. Summary of the Invention

[0041] Reference Figure 1-Figure 5A PVC sleeve processing surface grinding device includes a base plate 1. Two transverse guide rails 402 are fixed to the top of the base plate 1 by bolts. Clamping components 1 2 and 2 3 for supporting the PVC sleeve are provided on the two transverse guide rails 402. A distance adjustment component 5 for adjusting the distance between clamping components 1 2 and 2 3 is provided between the clamping components 1 2 and 2 3. A transverse moving component 4 is provided on the base plate 1 to drive clamping components 1 2 and 2 3 to move laterally. The transverse moving component 4 is a transverse moving electric push rod 401. The transverse moving electric push rod 401 is fixed to the upper surface of the base plate 1 by bolts. One end of the transverse moving electric push rod 401 is fixed to clamping component 1 2. A processing component 6 for grinding and chamfering the PVC sleeve is provided at the top of the base plate 1 and the end away from the transverse moving component 4.

[0042] The processing component 6 in this invention includes a bottom mounting frame 601 fixed to the upper surface of the base plate 1 by bolts. A lifting frame 604, which slides vertically, is provided on the top of the bottom mounting frame 601. A rotary cylinder 603 is fixed to the top of the lifting frame 604 by bolts. A rotating plate 605 is fixed to the rotating end of the rotary cylinder 603 by bolts. The top of the rotating plate 605 is provided with a grinding mechanism for grinding PVC sleeves and a chamfering mechanism for chamfering the ground PVC sleeves. The bottom mounting frame 601 contains a lifting mechanism that drives the lifting frame 604 to perform lifting and lowering actions. The electric push rod 602 and the grinding mechanism include a grinding frame 611 bolted to the upper surface of the rotating plate 605, a grinding motor 610 bolted to one side of the grinding frame 611, and a grinding disc 612 bolted to one end of the output shaft of the grinding motor 610.

A chamfering drill bit 607 is used for chamfering. A tool holder 613 is bolted to one side of the rotating plate 605. A scraper 606 for chamfering the outer ring of the PVC sleeve is detachably mounted on the top of the tool holder 613 via screws. The lifting electric push rod 602 is activated, extending to move the lifting frame 604 upwards until the center lines of the grinding disc 612 and the chamfering drill bit 607 coincide with the center line of the PVC sleeve. Then, the grinding motor 610 is activated, rotating the grinding disc 612 to perform the grinding operation. After grinding is completed, the grinding is stopped by starting... Rotary cylinder 603 rotates, causing rotating plate 605 to rotate 180°. At this time, chamfering motor 609 is started, which rotates chamfering drill bit 607 to chamfer the inner ring of PVC sleeve. After the inner ring of PVC sleeve is chamfered, lateral movement component 4 moves PVC sleeve backward to a designated position. Then, lifting electric push rod 602 is started, which extends to move lifting frame 604 upward until scraper 606 contacts the outer ring of PVC sleeve and performs chamfering operation on the outer ring of PVC sleeve.

[0043] The clamping assembly 2 and clamping assembly 3 of the present invention respectively include a movable frame 201 and a movable frame 301 slidably connected between two transverse guide rails 402 via a slide table. A support frame 211 is fixed to one side of both movable frame 201 and movable frame 301 by bolts. Two support rollers 210 for supporting PVC sleeves are rotatably connected to the top of the support frame 211. A guide block 204 is fixed to one side of both movable frame 201 and movable frame 301 by bolts. A clamping arm 203 is provided on one side of both movable frame 201 and movable frame 301, which slides in the vertical direction with the guide block 204. A clamping cylinder 202 is provided on one side of both movable frame 201 and movable frame 301 to drive the clamping arm 203 to rise and fall along the guide block 204. The ends of the two clamping arms 203 are respectively provided with a fixing mechanism for pressing and fixing the PVC sleeve and a driving mechanism for driving the PVC sleeve to rotate.

[0044] The fixing mechanism includes a pressure roller 208 rotatably connected to the end of the clamping arm 203 of the clamping assembly 2. The top of the clamping arm 203 of the clamping assembly 2 has a push groove 209. A push block 206 is slidably connected inside the push groove 209. The end of the push block 206 is fixed with a brake pad 207 that can contact the pressure roller 208 by bolts. The top of the clamping arm 203 of the clamping assembly 2 has a brake cylinder 205 that drives the push block 206 to move along the push groove 209.

[0045] The drive mechanism includes an active roller 304 rotatably connected to the end of the clamping arm 203 of clamping assembly 2. One end of the active roller 304 is bolted to a driven pulley 305. A drive motor 302 is bolted to the top of the clamping arm 203 of clamping assembly 2. One end of the output shaft of the drive motor 302 is bolted to a drive pulley 303 connected to the driven pulley 305 via belt drive. By placing the PVC sleeve between two support rollers 210, the PVC sleeve is supported. Then, by activating the clamping cylinder 202, the clamping cylinder 202 shortens, causing the clamping arm 203 to move downward along the guide block 204. At this time, the pressure roller 208 at the end of the clamping arm 203 of clamping assembly 2 and the clamping arm 203 of clamping assembly 2 are engaged. The three end drive rollers 304 are in contact with the PVC sleeve and press it down. When grinding and inner ring chamfering are performed, the brake cylinder 205 is activated. The brake cylinder 205 extends, causing the push block 206 to drive the brake pad 207 to move along the push groove 209 and contact the pressure roller 208, causing the pressure roller 208 to be braked and stopped, thereby fixing the PVC sleeve and facilitating grinding and inner ring chamfering. When chamfering the outer ring is performed, the fixed state of the PVC sleeve is released, and then the drive motor 302 is activated. The drive motor 302 rotates, causing the drive pulley 303 to drive the drive roller 304 to rotate through the driven pulley 305. At this time, the rotation of the drive roller 304 drives the PVC sleeve to rotate through friction, thereby completing the outer ring chamfering of the PVC sleeve.

[0046] The distance adjustment component 5 in this invention includes two cooperating guide sleeves 501 and guide rods 502 respectively welded to one side of clamping component 2 and clamping component 3. Threaded cylinders 503 are welded to one side of clamping component 2 and clamping component 3 respectively. A bidirectional threaded rod 504 is threadedly connected between the two threaded cylinders 503. By rotating the bidirectional threaded rod 504, the two threaded cylinders 503 drive clamping component 2 and clamping component 3 to move in opposite directions, thereby adjusting the distance between clamping component 2 and clamping component 3. Therefore, the length limits of the bidirectional threaded rod 504 and the two threaded cylinders 503 can be flexibly set according to the actual length of the PVC sleeve, adjusting the distance between clamping component 2 and clamping component 3, and is applicable to PVC sleeves of different lengths within a reasonable range.

[0047] The present invention is used in the following steps:

[0048] S1: First, based on the actual length of the PVC sleeve, rotate the double-threaded rod 504. The rotation of the double-threaded rod 504 causes the two threaded cylinders 503 to drive the clamping assembly 1 2 and the clamping assembly 2 3 to move in opposite directions, thereby adjusting the distance between the clamping assembly 1 2 and the clamping assembly 2 3.

[0049] S2: By placing the PVC sleeve between two support rollers 210, the PVC sleeve is supported. Then, by activating the clamping cylinder 202, the clamping cylinder 202 shortens and drives the clamping arm 203 to move downward along the guide block 204. At this time, the pressure roller 208 at the end of the clamping arm 203 of clamping component one 2 and the active roller 304 at the end of the clamping arm 203 of clamping component two 3 both contact the PVC sleeve and apply pressure.

[0050] S3: When performing grinding and inner ring chamfering operations, the brake cylinder 205 is activated. The brake cylinder 205 extends, causing the push block 206 to drive the brake pad 207 to move along the push groove 209 and contact the pressure roller 208, causing the pressure roller 208 to be braked and thus the PVC sleeve is fixed.

[0051] S4: Then start the lifting electric push rod 602. The lifting electric push rod 602 extends to move the lifting frame 604 upward until the center line of the grinding disc 612 and the chamfering drill bit 607 coincides with the center line of the PVC sleeve.

[0052] S5: At this time, start the transverse electric push rod 401. The transverse electric push rod 401 extends and drives the clamping assembly 1 2 and clamping assembly 2 3 to move, and makes the end of the PVC sleeve contact the grinding disc 612. Then start the grinding motor 610. The grinding motor 610 rotates and drives the grinding disc 612 to rotate and perform grinding operation.

[0053] S6: After grinding is completed, start the transverse electric push rod 401. The transverse electric push rod 401 shortens and drives the clamping assembly 1 2 and clamping assembly 2 3 to move, and makes the end of the PVC sleeve disengage from the grinding disc 612. Then, start the rotary cylinder 603. The rotary cylinder 603 rotates and drives the rotary plate 605 to rotate 180°.

[0054] S7: Then start the transverse electric push rod 401 again. The transverse electric push rod 401 extends and drives the clamping assembly 1 2 and clamping assembly 2 3 to move, and makes the end of the PVC sleeve contact the chamfering drill bit 607. Then start the chamfering motor 609. The chamfering motor 609 rotates and drives the chamfering drill bit 607 to rotate and chamfer the inner ring of the PVC sleeve.

[0055] S8: After the inner ring of the PVC sleeve is chamfered, start the transverse electric push rod 401. The transverse electric push rod 401 shortens and drives the clamping assembly 1 2 and clamping assembly 2 3 to move, and makes the end of the PVC sleeve disengage from the chamfering drill bit 607. Then, through the transverse component 4, the PVC sleeve is moved backward to the designated position. Then, by starting the lifting electric push rod 602, the lifting electric push rod 602 extends and moves the lifting frame 604 upward until the scraper 606 contacts the outer ring of the PVC sleeve.

[0056] S9: When chamfering the outer ring, the PVC sleeve is released from its fixed state. Then, the drive motor 302 is started. The drive motor 302 rotates, causing the drive pulley 303 to drive the drive roller 304 to rotate through the driven pulley 305. At this time, the rotation of the drive roller 304 drives the PVC sleeve to rotate through friction, so that the PVC sleeve completes the chamfering operation of the outer ring through the scraper 606.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
