Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, specifically a multi-station quick clamping fixture for valve bodies and flanges. Background Technology

[0002] The valve body is a key component of the fluid control system, such as Figure 3 As shown, flanges are welded to both ends of the fluid passage, connecting it to external pipelines; a flange is also welded to the top for securing the valve cover. A positioning device is required when assembling the valve body and flanges to ensure valve body stability.

[0003] However, the current positioning devices have the following problems: they can only be clamped by the end face of the valve body, or the clamping surface of the valve body is too small to clamp the valve body over a large area, resulting in unstable clamping. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-station quick clamping fixture for valve bodies and flanges, thereby solving the problems mentioned in the background section.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A multi-station quick-clamping fixture for valve bodies and flanges includes a base and a U-shaped wall plate fixed to one side of the base. The wall plate has two sets of vertically moving frames and a first drive mechanism that drives the two frames to move simultaneously or in opposite directions laterally. Each frame has two sets of clamping units arranged vertically and a second drive mechanism that drives the clamping units to move simultaneously or in opposite directions vertically. A support platform is located on the base between the two frames, providing initial support for the valve body. Furthermore, the support platform does not obstruct the movement of the two frames; that is, the two frames can slide behind the support platform.

[0006] Preferably, the clamping unit includes a lifting seat that is driven to the second drive mechanism, a first cylinder mounted on the lifting seat, and a pressure plate connected to the telescopic end of the first cylinder. The pressure plate is inclined, and a serrated rubber pad is fixed on the side of the pressure plate facing the lifting seat.

[0007] Preferably, the first driving mechanism includes a first lead screw rotatably connected to the top of the wall panel via a bearing, a first guide rod fixedly connected to the bottom of the wall panel, a first motor installed on one side of the top of the wall panel, and a first intermediate plate fixed in the middle of the top of the wall panel. The first motor is drivenly connected to one end of the first lead screw, and the first lead screw is rotatably connected to the first intermediate plate. The outer walls of the first lead screw on both sides of the first intermediate plate are provided with reverse threads. The translation frame is fixed with a transmission block and a slider on the side facing the wall panel. Both transmission blocks are provided with screw holes, and the two screw holes are respectively matched with the threads on both sides of the first lead screw. The two translation frames are threadedly connected to both sides of the first lead screw through the transmission blocks on them, and are slidably connected to the first guide rod through the slider.

[0008] The first motor is started, which drives the first lead screw to rotate. Since the threads on both sides of the first lead screw are set in opposite directions, when the first lead screw rotates, it drives the two transmission blocks to move in opposite directions at the same time, thereby driving the translation frame to move, that is, driving the clamping unit to move left and right to adapt to valve bodies of different lengths.

[0009] Preferably, the second drive mechanism includes a second lead screw rotatably connected to the translation frame via a bearing, a second guide rod fixedly connected to the translation frame, a second motor mounted on the upper end of the translation frame, and a second intermediate plate fixed to the translation frame. The second motor is drivenly connected to the upper end of the second lead screw, and the second lead screw is rotatably connected to the second intermediate plate. The outer walls of the second lead screw on both sides of the second intermediate plate are provided with reverse threads. The lifting seat is provided with a screw hole and a sliding hole, and the screw hole matches the second lead screw. Two lifting seats on the same translation frame are respectively threaded to both sides of the second lead screw and slidably connected to the second guide rod. The top surface of the lifting seat is provided with a first mounting groove, and the first cylinder is fixed in the first mounting groove.

[0010] Start the second motor to drive the second lead screw to rotate. Since the threads on both sides of the second lead screw are set in opposite directions, the rotation of the second lead screw will drive the two lifting seats to move in opposite directions at the same time, thereby driving the clamping unit to move up and down to adapt to valve bodies of different heights.

[0011] Preferably, each of the two clamping units has a backing plate fixed to the opposite surface of the two lifting seats.

[0012] When the first cylinder contracts, it drives the pressure plate to move towards the wall plate. The pressure plate pushes the valve body, while the backing plate can support the valve body. Through the dual action of the pressure plate and the backing plate, the valve body is clamped and kept stable.

[0013] Preferably, the base is provided with a second mounting groove, in which a second cylinder is installed, and the telescopic end of the second cylinder is connected to the support platform.

[0014] The support platform can perform initial positioning of the valve body. By controlling the second cylinder to operate, the support platform can be raised and lowered, adjusting the height of the valve body so that the four clamping units can accurately position the valve body.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The first drive mechanism controls the left and right movement of the two translation frames, which can adjust the distance between the two translation frames to accommodate valve bodies of different lengths. The second drive mechanism controls the up and down movement of the two clamping units on the same translation frame, which can accommodate valve bodies of different heights, thus improving adaptability.

[0016] By having four sets of clamping units work simultaneously, the valve body can be surrounded over a large area to fix it in place, so that the flange can be welded to the valve body from multiple directions at the same time. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 Please see Figure 1-2 A multi-station quick clamping fixture for valve bodies and flanges includes a base 1, a U-shaped wall plate 2 fixed to one side of the base, two sets of vertical translation frames 3 on the wall plate 2, and a first drive mechanism that drives the two translation frames 3 to move simultaneously in opposite directions in the lateral direction.

[0020] Specifically, the first driving mechanism includes a first lead screw 6 rotatably connected to the wall panel 2 via bearings, a first guide rod 7 fixedly connected to the bottom of the wall panel, a first motor 8 installed on one side above the wall panel, and a first intermediate plate 9 fixed in the middle of the upper part of the wall panel. The first motor 8 is drivenly connected to one end of the first lead screw 6, and the first lead screw 6 is rotatably connected to the first intermediate plate 9. The outer walls of the first lead screw 6 on both sides of the first intermediate plate 9 are provided with reverse threads. The translation frame 3 is fixed with a transmission block 10 and a slider 11 on the side facing the wall panel. Both transmission blocks are provided with screw holes, and the two screw holes are respectively matched with the threads on both sides of the first lead screw. The two translation frames 3 are threadedly connected to both sides of the first lead screw 6 through the transmission blocks 10 on them, and the two translation frames are slidably connected to the first guide rod 7 through the sliders 11 on them.

[0021] Start the first motor 8, which drives the first lead screw 6 to rotate. Since the threads on both sides of the first lead screw 6 are reversed, when the first lead screw 6 rotates, it drives the two transmission blocks 10 to move relative to each other or in opposite directions at the same time, thereby driving the translation frame to move horizontally.

[0022] The translation frame 3 is provided with two sets of clamping units 4 arranged vertically and vertically, as well as a second driving mechanism that drives the two clamping units 4 to move vertically simultaneously relative to each other or in opposite directions.

[0023] Specifically, the second drive mechanism includes a second lead screw 12 rotatably connected to the translation frame 3 via a bearing, a second guide rod 13 fixedly connected to the translation frame, a second motor 14 mounted on the upper end of the translation frame, and a second intermediate plate 15 fixed to the translation frame. The second motor 14 is drivenly connected to the upper end of the second lead screw 12, and the second lead screw 12 is rotatably connected to the second intermediate plate 15. The outer walls of the second lead screw 12 on both sides of the second intermediate plate are provided with reverse threads. Two lifting seats 401 on the same translation frame 3 are respectively threaded to both sides of the second lead screw 12, and the lifting seats are slidably connected to the second guide rod 13.

[0024] Start the second motor 14 to drive the second lead screw 12 to rotate. Since the threads on both sides of the second lead screw 12 are set in opposite directions, the rotation of the second lead screw 12 will drive the two clamping units to move in opposite directions at the same time.

[0025] The clamping unit 4 includes a lifting seat 401 threaded onto a second lead screw, a first cylinder 402 mounted on the lifting seat, and a pressure plate 403 connected to the telescopic end of the first cylinder. The top surface of the lifting seat 401 has a first mounting groove, and the first cylinder 402 is fixed within the first mounting groove. The pressure plates 403 are inclined, meaning the extension lines of the four pressure plates form an "X" shape. A serrated rubber pad is fixed to the side of the pressure plate 403 facing the lifting seat to reduce wear on the valve body. A backing plate 404 is fixed to the opposite surfaces of the two clamping units 4 relative to the two lifting seats 401 to support the back of the valve body.

[0026] A support platform 5 is provided on the base 1 in front of the two translation frames 3, and the support platform is located on the central axis between the two translation frames. The support platform provides initial support for the valve body. In addition, the support platform does not obstruct the movement of the two translation frames, that is, the two translation frames can slide behind the support platform.

[0027] The working principle of this embodiment is as follows: The valve body 18 is placed on the support platform 5, centered. Then, the first drive mechanism controls the two translation frames 3 to move left and right, adjusting the distance between them to accommodate valve bodies of different lengths. Next, the second drive mechanism controls the two clamping units 4 on the same translation frame 3 to move up and down, accommodating valve bodies of different heights. Once the four clamping units 4 are positioned at the four corners of the valve body, the first cylinder 402 extends, causing the pressure plate 403 to reach the front of the valve body. Then, through the operation of the first and second drive mechanisms, the four clamping units 4 are positioned close to the four corners of the valve body (e.g.,...). Figure 2 (As shown), then control the first cylinder 402 to retract, driving the pressure plate 403 to move backward, and press the valve body tightly against the back plate 404 through the pressure plate 403, thereby fixing the valve body.

[0028] This embodiment protects a clamp for the valve body. After the valve body is fixed, flanges can be installed from both sides and top of the valve body, and the flanges can be welded to both ends and top of the valve body to achieve multi-station assembly.

[0029] Example 2 The base 1 is provided with a second mounting groove 16, in which a second cylinder 17 is installed. The telescopic end of the second cylinder 17 is connected to the support platform 5. The support platform can perform preliminary positioning of the valve body. By controlling the operation of the second cylinder, the support platform can be raised and lowered, thereby adjusting the height of the valve body so that the four clamping units can accurately position the valve body.

[0030] This invention also requires an air pump, a control valve, and an air supply line to provide power to the cylinder. Providing power to the cylinder via an air pump is a conventional technique in this field and will not be described in detail here.
