Description

Technical Field

[0001] The utility model relates to the technical field of metal pipe processing, in particular to a multi-station clamping device for metal pipe processing. Background Art

[0002] Pipe fittings are a general term for parts and components in pipeline systems that play roles in connection, control, direction change, diversion, sealing, and support. During the production and processing of pipe fittings, welding, grinding, polishing, cutting, and other work may be required. Therefore, the pipe blanks need to be clamped by a clamping device, and a multi-station clamping device can clamp multiple pipe fittings at the same time for simultaneous processing.

[0003] The existing multi-station clamping devices for metal pipe processing are mainly divided into split type and linkage type. The split type means that multiple stations control clamping and opening separately, which is more flexible but more expensive. The linkage type means that multiple stations are linked to each other and control clamping and opening at the same time, which is less expensive but less flexible.

[0004] The existing linkage multi-station clamping device for metal pipe processing is usually fixed by rigid connection due to the linkage between multiple stations. When the clamping plate is worn and replaced, multiple stations need to be replaced as a whole, which wastes a lot of angle. Although the disassembly and assembly by bolting does not remove all stations at the same time, it requires the additional disassembly and assembly of several bolts, which is more cumbersome. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a multi-station clamping device for metal pipe processing to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-station clamping device for metal pipe processing, comprising a device body, a clamping seat and a clamping block, a motor is installed on the outer surface of the device body, and a gear is connected to the output end of the motor, a first linkage rod and a second linkage rod are passed through both sides of the top of the device body, slots are provided on both sides of the clamping seat, a slider is connected to the bottom of the clamping block, a slide groove is provided on the outer surface of the clamping block, and a sleeve is connected to the outer surface of the slide groove.

[0007] By adopting the above technical solution, when disassembly and assembly is required, the sleeve is slid upward to separate the sleeve from the first linkage rod and the second linkage rod, and then the clamp block can be removed from the clamp seat by sliding it horizontally; when assembling, the slider is inserted into the slot horizontally, and the slot and the slider cooperate to prevent the clamp block from falling off upward, and then the sleeve is slid upward and then the clamp block is continued to slide horizontally to make the sleeve correspond to the first linkage rod or the second linkage rod, and then the sleeve is released, and the sleeve is moved down by gravity to be sleeved on the top of the first linkage rod or the second linkage rod, thereby completing the limiting work.

[0008] Furthermore, the first linkage rod and the second linkage rod are both in a "mountain" shape, and the first linkage rod and the second linkage rod are both slidably connected to the device body.

[0009] By adopting the above technical solution, the first linkage rod and the second linkage rod are both in a mountain shape, so as to respectively drive the two groups of clamping blocks to move towards each other to clamp the pipe blank.

[0010] Furthermore, the top of the first linkage rod is provided with teeth, and the bottom of the second linkage rod is provided with teeth, and the gear is respectively meshed with the teeth on the top of the first linkage rod and the teeth on the bottom of the second linkage rod.

[0011] By adopting the above technical solution, after the motor is started, the output end driving gear rotates counterclockwise, so that the first linkage rod and the second linkage rod move relative to each other. After the first linkage rod and the second linkage rod are displaced, the two groups of clamping blocks are driven to move toward each other through the two groups of sleeves, thereby clamping the pipe blank.

[0012] Furthermore, the cross-sections of the slot and the slider are both in an inverted "T" shape, and the slider is detachably connected to the slot by sliding.

[0013] By adopting the above technical solution, the staff inserts the slider into the slot horizontally, and the slot cooperates with the slider to prevent the clamp from falling off upwards.

[0014] Furthermore, the clamping block, the first linkage rod, the second linkage rod, the slot, the slider, the sleeve and the slide groove are each provided with two groups, and the clamping seat is provided with three groups.

[0015] By adopting the above technical solution, since two groups of clamping blocks are provided and three clamping seats are provided, it is convenient to clamp three pipe blanks at the same time, which is suitable for multi-station processing.

[0016] Furthermore, one group of the sleeves is detachably connected to the first linkage rod, and another group of the sleeves is detachably connected to the second linkage rod.

[0017] By adopting the above technical solution, the sleeve is moved downward by gravity to be sleeved on the top end of the first linkage rod or the second linkage rod, thereby completing the position limiting work.

[0018] Furthermore, the sleeve is slidably connected to the clamping block via a sliding groove.

[0019] By adopting the above technical solution, the staff slides the sleeve upward and then continues to slide the clamping block horizontally to make the sleeve correspond to the first linkage rod or the second linkage rod. Then the staff loosens the sleeve and uses gravity to move the sleeve down and sleeve on the top of the first linkage rod or the second linkage rod.

[0020] Furthermore, the clamping seat is fixed in the middle of the top of the device body, and the clamping block is connected to one side of the top of the clamping seat.

[0021] By adopting the above technical solution, the two groups of clamping blocks move toward each other, thereby clamping the pipe blank.

[0022] Furthermore, a first clamping pad is connected to the top of the clamp seat, and a second clamping pad is connected to one side of the bottom of the clamping block. The two groups of clamping blocks are away from each other, thereby completing the clamping and limiting of the pipe blank.

[0023] By adopting the above technical solution, the friction between the first clamping pad and the second clamping pad is increased through the cooperation between the first clamping pad and the pipe blank, thereby preventing the pipe blank from falling off.

[0024] Furthermore, the first clamping pad and the second clamping pad are both made of rubber material, and the surfaces of the first clamping pad and the second clamping pad are both rough.

[0025] By adopting the above technical solution, the rubber itself has a large friction force, and the rubber with a rough surface further increases the friction force between the pipe blank and the clamp seat and the clamp block.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] The utility model arranges the first linkage rod, the second linkage rod, the slot, the slider, the sleeve and the slide groove. When disassembly and assembly is required, the sleeve is slid upward, so that the sleeve is separated from the first linkage rod and the second linkage rod. Then, the clamping block can be taken out from the clamping seat by sliding it horizontally. When assembling, the slider is inserted into the slot horizontally, and the clamping block is prevented from falling off upward by the cooperation between the slot and the slider. Then, the sleeve is slid upward and then the clamping block is continued to slide horizontally, so that the sleeve corresponds to the first linkage rod or the second linkage rod. Then, the sleeve is loosened, and the sleeve is moved down and sleeved on the top of the first linkage rod or the second linkage rod by gravity, so that the limiting work is completed. The disassembly and assembly operation is very simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0034] The following describes an embodiment of the utility model based on its overall structure.

[0035] Embodiment 1:

[0036] A multi-station clamping device for metal pipe processing, such as Figure 1-Figure 4 As shown, it includes a device body 1, a clamp seat 2 and a clamp block 3. A motor 6 is installed on the outer surface of the device body 1. The output end of the motor 6 is connected to a gear 7. The first linkage rod 8 and the second linkage rod 9 are penetrated on both sides of the top of the device body 1. The first linkage rod 8 and the second linkage rod 9 are both in the shape of a "mountain". The top of the first linkage rod 8 is provided with teeth, and the bottom of the second linkage rod 9 is provided with teeth. The gear 7 is respectively engaged with the teeth at the top of the first linkage rod 8 and the bottom of the second linkage rod 9. The first linkage rod 8 and the second linkage rod 9 are both slidably connected to the device body 1. After the motor 6 is started, the output end drives the gear 7 to rotate counterclockwise, so that the first linkage rod 8 and the second linkage rod 9 move relative to each other. The first linkage rod 8 and the second linkage rod 9 are displaced and then drive the two groups of clamp blocks 3 to move toward each other through two groups of sleeves 12, so as to clamp the pipe blank;

[0037] Slots 10 are provided on both sides of the clamp seat 2, and a slider 11 is connected to the bottom of the clamp block 3. The cross-sections of the slot 10 and the slider 11 are both in an inverted "T" shape. The slider 11 is detachably connected to the slot 10 by sliding. The slider 11 is inserted into the slot 10 horizontally, and the slot 10 cooperates with the slider 11 to prevent the clamp block 3 from falling off upward; a slide groove 13 is provided on the outer surface of the clamp block 3, and a sleeve 12 is connected to the outer surface of the slide groove 13. The clamp block 3, the first linkage rod 8, the second linkage rod 9, the slot 10, the slider 11, the sleeve 12 and There are two groups of slide grooves 13 and three clamping seats 2. One group of sleeves 12 is detachably connected to the first linkage rod 8, and the other group of sleeves 12 is detachably connected to the second linkage rod 9. The sleeve 12 is slidably connected to the clamping block 3 through the slide groove 13. The sleeve 12 is slid upward and then the clamping block 3 is continued to slide horizontally to make the sleeve 12 correspond to the first linkage rod 8 or the second linkage rod 9. Then the staff releases the sleeve 12 and uses gravity to move the sleeve 12 down and sleeve it on the top of the first linkage rod 8 or the second linkage rod 9, thereby completing the limiting work.

[0038] See also Figure 1-Figure 3 In the above embodiment, the clamp seat 2 is fixed in the middle of the top of the device body 1, and the clamp block 3 is connected to one side of the top of the clamp seat 2. The two groups of clamp blocks 3 move toward each other to clamp the pipe blank.

[0039] Embodiment 2:

[0040] On the basis of the above-mentioned embodiment 1, in order to increase the stability of clamping, the following settings are adopted.

[0041] See also Figure 1-Figure 4 In the above embodiment, a first clamping pad 4 is connected to the top of the clamping seat 2, and a second clamping pad 5 is connected to one side of the bottom of the clamping block 3. The first clamping pad 4 and the second clamping pad 5 are both made of rubber material, and the first clamping pad 4 and the second clamping pad 5 have rough surfaces. The first clamping pad 4 and the second clamping pad 5 cooperate to increase the friction between the pipe blank and prevent the pipe blank from falling off.

[0042] The implementation principle of the utility model is as follows: first, the staff places the pipe blank on the clamp seat 2, and then the staff turns on the motor 6. After the motor 6 is started, the output end driving gear 7 rotates counterclockwise, so that the first linkage rod 8 and the second linkage rod 9 move relative to each other. After the first linkage rod 8 and the second linkage rod 9 are displaced, the two groups of clamping blocks 3 are driven to move toward each other through the two groups of sleeves 12, so as to clamp the pipe blank. Then the staff turns off the motor 6, and at the same time, the first clamping pad 4 and the second clamping pad 5 cooperate to increase the friction between the pipe blank and the pipe blank to prevent the pipe blank from falling off;

[0043] After the processing is completed, the staff turns on the motor 6 again, and the output end of the motor 6 drives the gear 7 to rotate clockwise, so that the first linkage rod 8 and the second linkage rod 9 move away from each other, and then the tension is transmitted through the two sets of sleeves 12 to move the two sets of clamping blocks 3 away from each other, thereby ending the clamping and limiting of the pipe blank;

[0044] When a clamping block 3 is damaged and needs to be replaced separately, the staff slides the sleeve 12 upward, so that the sleeve 12 is separated from the first linkage rod 8 or the second linkage rod 9, and then the staff slides the clamping block 3 horizontally to remove the clamping block 3 from the clamping seat 2;

[0045] During assembly, the staff inserts the slider 11 into the slot 10 horizontally, and the slot 10 cooperates with the slider 11 to prevent the clamp 3 from falling off upward. Then the staff slides the sleeve 12 upward and continues to slide the clamp 3 horizontally, so that the sleeve 12 corresponds to the first linkage rod 8 or the second linkage rod 9. Then the staff releases the sleeve 12, and gravity moves the sleeve 12 down and sleeves it on the top of the first linkage rod 8 or the second linkage rod 9, thereby completing the limiting work.
