[0020] Beneficial effects

[0021] Compared with the prior art, the present invention provides a valve processing platform that can rotate at multiple angles, which has the following beneficial effects:

[0022] 1. The present invention realizes 360° stepless rotation positioning through the worm gear and worm transmission system and the ball guide structure. The first worm and the first worm gear reduction ratio are matched, and the multiple first balls distributed in an annular shape are combined to improve the rotation accuracy of the turntable. At the same time, the self-locking characteristics of the worm gear ensure that there is no displacement during processing. Compared with the traditional screw adjustment method, the operating efficiency is improved.

[0023] 2. The present invention realizes four-way linkage precise alignment through the synchronous clamping mechanism of the ring plate and the guide hole. The four groups of sliders move synchronously radially along the annular guide hole, and the rotational feed rate driven by the second worm gear ensures that the center positioning error is small when the clamping plate is closed, solving the problem that manual adjustment cannot accurately align the center.

[0024] 3. The present invention realizes the automatic centering positioning of the valve through the spring pre-tightened abutment plate limit system. The four independent abutments form a conical guide surface under the action of the spring. When the valve is pressed down, the abutment plates are triggered to contract radially, which shortens the automatic alignment time of the workpiece and improves the positioning repeatability accuracy.

[0025] 4. The present invention realizes the rapid adaptation of valves of various specifications through the adjustable square rod clamping assembly. The clamping plate can be linearly adjusted within a certain range through the square rod. Combined with the locking torque of the fixing bolt, the clamping range covers valves of various specifications, thereby improving the versatility of the equipment.

[0026] 5. The present invention uses the gap formed by the connecting rod and the circular ring to allow the waste chips generated during processing to pass through the turntable cavity and fall into the table body for collection, thereby solving the problem that the valve cannot be placed flat on the table due to waste chips. In addition, when the abutment plate returns to its position, the waste chips on the top of the connecting rod in the moving range can be cleaned up. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Reference Figures 1-6A multi-angle rotatable valve processing platform includes a platform 100, a limiting mechanism 200 for limiting the placement of the valve is provided on the top of the platform 100, a rotating mechanism 300 for enabling the limiting mechanism 200 to achieve circular rotation is provided on the top of the platform 100, and a fixing mechanism 400 for clamping the valve is provided on the rotating mechanism 300.

[0038] The rotating mechanism 300 includes a turntable 301 rotatably connected to the platform 100 . A first worm gear 302 is coaxially arranged on the lower layer of the turntable 301 . A first worm 303 is rotatably connected to the inner wall of the platform 100 through a bearing. The first worm 303 is engaged with the first worm gear 302 .

[0039] Specifically, through the arrangement of the first worm gear 302 and the second worm 408, the first worm gear 302 can be driven to rotate when the first worm gear 303 rotates, thereby realizing the rotation of the turntable 301, thereby realizing the rotation of the limiting mechanism 200 and the fixing mechanism 400, and rotating the valve fixed thereon, realizing the function of multi-angle rotation adjustment, meeting different processing requirements, and improving the scope of application. When the first worm gear 303 stops rotating, it has the function of self-locking the first worm gear 302, so that the first worm gear 302 will not rotate without the rotation of the first worm gear 303, and thus will not rotate when the rotation stops.

[0040] In the present invention, one end of the first worm 303 is fixedly connected to the first handle 305 , and a first ball 304 is provided between the inner surface of the platform 100 and the outer surface of the turntable 301 .

[0041] Specifically, by setting the first handle 305, rotating it can easily drive the first worm 303 to rotate, which is more convenient and labor-saving. There are several first balls 304, and the inner surface of the table 100 and the outer surface of the turntable 301 are respectively provided with annular grooves that cooperate with the first balls 304. The turntable 301 is limited on the table 100 by the first balls 304, and at the same time will not affect the rotation of the turntable 301.

[0042] In the present invention, the fixing mechanism 400 includes a circular ring 401 fixedly connected to the top of the turntable 301, a ring plate 402 is rotatably connected to the outer surface of the circular ring 401, a slider 403 is slidably connected to the ring plate 402, a short column 404 is fixedly connected to the top of the slider 403, a guide hole 405 is opened on the top of the ring plate 402 and matches the short column 404, and the short column 404 is slidably connected to the guide hole 405.

[0043] Specifically, there are four sliders 403 and four short columns 404, and there are four guide holes 405 on the ring plate 402. By rotating the ring plate 402, the short columns 404 can move in the guide holes 405, thereby making the four sliders 403 approach or move away from each other, thereby driving the multiple groups of connecting blocks 410, square rods 411 and clamping plates 412 thereon to approach or move away from each other, thereby fixing or releasing the valve.

[0044] In the present invention, a second worm gear 406 is fixedly sleeved on the outer surface of the ring plate 402, a fixed block 407 is fixedly connected to the outer surface of the turntable 301, a second worm 408 is rotatably connected to the fixed block 407 through a bearing, and one end of the second worm 408 is fixedly connected to a second handle 409.

[0045] Specifically, there are two fixing blocks 407, and both ends of the second worm 408 are rotatably connected to the two fixing blocks 407 through bearings. Through the arrangement of the second worm 408 and the second worm wheel 406, when the second handle 409 is rotated, the second worm 408 is rotated, thereby driving the second worm wheel 406 to rotate, causing the ring plate 402 to rotate to drive the short column 404, thereby moving the slider 403 and the connecting block 410, square rod 411 and clamping plate 412 thereon, so that the multiple clamping plates 412 are close to or away from each other, thereby fixing or releasing the valve, and when the second worm 408 stops rotating, it has the function of self-locking the second worm wheel 406, so that the second worm wheel 406 will not rotate without the rotation of the second worm 408, and the clamping plate 412 will not loosen after clamping the valve, effectively achieving stable clamping and fixation.

[0046] In the present invention, a connecting block 410 is fixedly connected to the top of the slider 403, a square rod 411 is slidably connected to the connecting block 410, a splint 412 is fixedly connected to one end of the square rod 411, a fixing bolt 413 is threadedly connected to the top of the connecting block 410, and the lower end of the fixing bolt 413 is in contact with the top of the square rod 411.

[0047] Specifically, the square rod 411 passes through the connecting block 410 and is slidably connected thereto. The position of the clamping plate 412 can be adjusted through the square rod 411, thereby improving the scope of application. Valves of different specifications can also be clamped and fixed without adjustment. When the clamping requirements cannot be met, the square rod 411 is moved on the connecting block 410 according to the actual situation, and the position of the clamping plate 412 is adjusted. When clamping, the ring plate 402 is rotated to move the slider 403, driving the connecting block 410, square rod 411 and clamping plate 412 thereon to approach each other, thereby fixing the valve. The square rod 411 that has been moved and adjusted on the connecting block 410 can be fixed by the fixing bolt 413, and then the distance of the adjusted clamping plate 412 away from the connecting block 410 is fixed.

[0048] In the present invention, a rubber pad 414 is fixedly connected to the side of the clamping plate 412 away from the square rod 411 , and a second ball 415 is provided between the outer surface of the ring 401 and the inner surface of the ring plate 402 .

[0049] Specifically, the rubber pad 414 can increase the friction between the valve and the valve, improve the fixing effect, and protect the valve when it is clamped and fixed. There are several second balls 415, and the outer surface of the ring 401 and the inner surface of the ring plate 402 are respectively provided with arc grooves that match the second balls 415. The ring plate 402 is limited to the ring 401 by the second balls 415, and the rotation of the ring plate 402 is not affected.

[0050] In the present invention, the limiting mechanism 200 includes a connecting rod 201 fixedly connected to the inner surface of the ring 401, one end of the connecting rod 201 is fixedly connected to a block 202, a sliding sleeve is provided on the surface of the connecting rod 201 with a support plate 203, a short block 205 is fixedly connected to the bottom of the connecting rod 201, and a spring 204 is fixedly connected between the short block 205 and the support plate 203.

[0051] Specifically, there are four connecting rods 201, abutment plates 203, short blocks 205 and springs 204. The four connecting rods 201 are arranged in a circular array on the inner surface of the ring 401. The abutment plates 203 are guided and supported by the connecting rods 201, and the flange of the valve inserted into the abutment plates 203 is supported, thereby supporting the valve. At the same time, the gap formed with the ring 401 facilitates the waste generated during processing to pass through the cavity of the turntable 301 and fall into the table body 100 for collection, so as to avoid the valve being unable to be placed flat due to waste when it is placed on the table. When the valve is placed vertically, the hollow part of its lower end gradually contacts the abutment plates. The upper end of 203 contacts and moves downward. Due to the shape design of the support plate 203, the four support plates 203 move closer to each other as they move downward, and the spring 204 is stretched. When the valve is completely covered on the support plate 203, the bottom contacts the top of the connecting rod 201. Under the action of the spring 204 pulling back, the four support plates 203 are in precise contact with the valve, thereby achieving initial limit fixation. There is no need to manually adjust the valve position until it is fixed by the clamping plate 412. When the valve is removed, the return of the support plate 203 can clean up the waste on the top of the connecting rod 201 within the moving range to ensure that it is flat when placed next time.

[0052] In the present invention, a guide rod 206 is provided through one side of the abutment plate 203 , and both ends of the guide rod 206 are fixedly connected to the connecting rod 201 and the block 202 respectively, and the spring 204 is sleeved on the surface of the guide rod 206 .

[0053] Specifically, by providing the guide rod 206 , the short block 205 is guided and supported, thereby supporting the connecting rod 201 , thereby improving its stability and strength.

[0054] In the present invention, a collecting frame 500 is plugged into one side of the platform 100 , and a cover 600 is fixedly connected to the top of the ring plate 402 .

[0055] Specifically, the collection frame 500 facilitates the collection of waste chips that fall into the platform 100, making it easier for subsequent operators to take them out. The cover body 600 shields the ring plate 402, the second worm gear 406 and the second worm 408 therein to avoid damage to the human body.

[0056] Working principle of the present invention:

[0057] S1. The valve is vertically moved downward so that the hollow portion at its lower end gradually contacts the upper end of the retaining plate 203. Due to the shape of the retaining plate 203, the four retaining plates 203 move closer to each other as they move downward, and the spring 204 is stretched. When the valve is completely sleeved on the retaining plate 203, the bottom contacts the top of the connecting rod 201. Under the action of the spring 204 pulling back, the four retaining plates 203 precisely contact the valve, thereby achieving initial position fixation.

[0058] S2. Turn the second handle 409 to rotate the second worm 408, which in turn drives the second worm wheel 406 to rotate, causing the ring plate 402 to rotate to drive the short column 404, thereby moving the slider 403 and the connecting block 410, square rod 411 and clamping plate 412 thereon, so that the multiple clamping plates 412 are close to each other, thereby fixing the valve;

[0059] S3. When the rotation angle is required, the first handle 305 is turned to rotate the second worm 408, thereby rotating the turntable 301, thereby rotating the limiting mechanism 200 and the fixing mechanism 400, and rotating the valve fixed thereon, to achieve multi-angle rotation adjustment. When the valve is removed, the above fixing operation can be reversed.

[0060] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, 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.

[0061] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
