Description

Technical Field

[0001] The present application relates to the field of mechanical manufacturing technology, and in particular to a clamping and positioning device and processing equipment. Background Art

[0002] The positioning fixture usually includes multiple jaws located in different directions. Multiple jaws are close to the workpiece for clamping and fixing. The moving distances of different jaws when approaching the workpiece are prone to differences, resulting in the inability of each jaw to clamp each clamping surface of the workpiece synchronously, affecting the clamping stability of the workpiece.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0045] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings:

[0046] refer to Figure 1 and Figure 2 According to the first aspect of the present application, the clamping and positioning device includes a base 100, a driving assembly 300, a guide member 400 and at least two clamping assemblies 200. The base 100 is provided with a stage 110 for carrying a workpiece 500. At least two clamping assemblies 200 are slidably connected to the base 100. The driving assembly 300 is arranged on the base 100 and connected to each clamping assembly 200. The driving assembly 300 is used to drive each clamping assembly 200 to slide relative to the base 100 in a horizontal direction so that each clamping assembly 200 can synchronously approach the stage 110 to clamp the workpiece 500. The guide member 400 is slidably connected to at least two clamping assemblies 200. The guide member 400 is used to drive each clamping assembly 200 moving in the horizontal direction to move in the vertical direction at the same time. Under the joint drive of the driving assembly 300 and the guide member 400, each clamping assembly 200 simultaneously includes movement in the horizontal direction and movement in the vertical direction. Each clamping assembly 200 synchronously slides in the horizontal direction relative to the base 100, and the force on each side of the clamped workpiece 500 is more balanced, which is beneficial to ensuring the stability of clamping. The guide member 400 drives the clamping assembly 200 to move in the vertical direction, and clamping workpieces 500 of different sizes has different clamping heights, which effectively improves the applicability of clamping workpieces 500 of different sizes.

[0047] It should be noted that the clamping and positioning device clamps workpieces 500 of different sizes in two aspects: first, the driving assembly 300 drives each clamping assembly 200 to move in the horizontal direction to adapt to the horizontal size of the workpiece 500; second, the guide member 400 drives each clamping assembly 200 to move in the vertical direction to adapt to the vertical size of the workpiece 500. Different clamping heights can be used for workpieces 500 of different sizes. Compared with a clamp that can only move and clamp the workpiece 500 in a single direction, it is suitable for clamping more workpieces 500 of different sizes and has a wider range of application for clamping the workpiece 500.

[0048] Specifically, each clamping assembly 200 approaches the workpiece 500 synchronously under the drive of the driving assembly 300, and each clamping assembly 200 moves at the same speed in the horizontal direction, so that each clamping assembly 200 has a relatively balanced clamping force on each clamped surface of the workpiece 500, avoiding damage to the workpiece 500 caused by excessive local stress, which is beneficial to ensuring the processing quality. Under the drive of the guide member 400, each clamping assembly 200 can also move in the vertical direction. The power source of the guide member 400 driving the clamping assembly 200 can come from the driving assembly 300 or from itself. The driving assembly 300 can include power parts such as cylinders. Under the drive of the guide member 400, each clamping assembly 200 can have different clamping heights when clamping workpieces 500 of different sizes and / or shapes, effectively reducing the situation of adjusting the clamping height of the workpiece 500 by replacing the fixture or disassembling the clamping jaws, which is beneficial to improving the processing efficiency.

[0049] refer to Figure 1 and Figure 2 In some embodiments, the driving assembly 300 includes a driving member 310 and a transmission member 320. The driving member 310 is fixed on the base 100 and is transmission-connected to the transmission member 320. The transmission member 320 is rotationally connected to the base 100, and the transmission member 320 is also transmission-connected to each clamping assembly 200. The driving member 310 is used to drive the transmission member 320 to rotate relative to the base 100. The rotation of the transmission member 320 relative to the base 100 can simultaneously transmit power to each clamping assembly 200, so that each clamping assembly 200 slides relative to the base 100 in a horizontal direction to When approaching or moving away from the stage 110 and each clamping assembly 200 slides relative to the base 100, the guide member 400 provides a guiding function for at least two clamping assemblies 200. At the same time, each clamping assembly 200 slidably connected to the guide member 400 can drive other clamping assemblies 200 to move together in the vertical direction. The movement of each clamping assembly 200 in the horizontal direction and in the vertical direction is powered by the driving member 310. Compared with using different power sources to drive each clamping assembly 200, the structure of the clamping and positioning device is simplified, which is beneficial to reducing production costs.

[0050] It should be noted that the driving member 310 can be a cylinder, and the transmission member 320 can be a gear 321. The driving member 310 realizes a transmission connection with the transmission member 320 through the meshing transmission of the second rack 311 and the gear 321. The sliding connection between the guide member 400 and each clamping component 200 can be a structure with a guiding function such as a groove, a pulley, and a slide rail. A first rack 212 may also be provided on each clamping component 200. Each clamping component 200 is meshed with the transmission member 320 at the same time through the first rack 212, and the meshing positions of each clamping component 200 and the transmission member 320 are different to avoid each other and avoid interference during the transmission process with the transmission member 320. Since each clamping assembly 200 is located at a different position of the stage 110, at least two clamping assemblies 200 are connected to the guide member 400, which effectively ensures that each clamping assembly 200 can move together in the vertical direction, avoiding the deviation of the plane where each clamping assembly 200 is located relative to the horizontal plane, which is beneficial to improving the smoothness of the movement of each clamping assembly 200 in the vertical direction.

[0051] refer to Figure 1 and Figure 2 In some embodiments, a groove is provided on the guide member 400 and extends toward the stage 110, and the extension direction has an angle with the horizontal direction and the vertical direction. A rotatable roller is provided on the clamping assembly 200, and the roller is placed in the groove and rolls. Under the guiding action of the groove, the clamping assembly 200 can move along the extension direction of the groove, that is, the clamping assembly 200 includes movement in the vertical direction and the horizontal direction at the same time. In addition, the clamping assembly 200 can drive the driving assembly 300 to move in the vertical direction together, so that each clamping assembly 200 connected to the driving assembly 300 can move synchronously in the vertical direction. Therefore, each clamping assembly 200 includes movement in the horizontal direction and the vertical direction under the joint action of the driving assembly 300 and the guide member 400, so as to better adaptably clamp the workpiece 500.

[0052] refer to Figure 1 and Figure 2 In other embodiments, a guide rail extending toward the stage 110 is provided on the guide member 400, and an angle is formed between the extending direction and the horizontal direction and the vertical direction. A slider is provided on the clamping assembly 200, and the clamping assembly 200 is slidably connected to the guide rail through the slider. The sliding between the slider and the guide rail can be driven by the driving assembly 300, or by another power source. By slidingly connecting the slider and the guide rail, the clamping assembly 200 can include a compound movement in the vertical direction and the horizontal direction at the same time, which is beneficial to better adapt to the clamping needs.

[0053] refer to Figures 1 to 3In some embodiments, the clamping assembly 200 includes a connecting member 210 and a clamping member 220 connected to each other, and the connecting member 210 and the transmission member 320 are transmission-connected. In the vertical direction, the worktable 110 is located between the clamping member 220 and the connecting member 210, wherein the clamping member 220 is located on the side of the worktable 110 for clamping the workpiece 500, and the connecting member 210 is located on the side of the worktable 110 away from the clamping member 220. The connecting member 210 and the clamping member 220 are respectively located on both sides of the worktable 110, and the transmission member 320 simultaneously drives each connecting member 210 to move, so as to drive each clamping member 220 to approach or move away from the worktable 110 in the horizontal direction, so as to avoid mutual interference between the connecting member 210 and the clamping member 220 when clamping the workpiece 500.

[0054] In other embodiments, the length of the connecting member 210 can be adjusted. By adjusting the length of the connecting member 210, the applicable range of the clamping workpiece 500 of the clamping and positioning device can be adjusted, which is beneficial to improving the flexibility of the clamping and positioning device.

[0055] refer to Figures 1 to 4 In some embodiments, at least one of the clamping assemblies 200 includes a clamping portion 221 and an elastic portion 222 connected to each other. In the vertical direction, the clamping portion 221 and the elastic portion 222 are located on one side of the stage 110 for carrying the workpiece 500. The clamping portion 221 can compress the elastic portion 222 in the horizontal direction. According to the different sizes of the workpiece 500 clamped by the clamping and positioning device, the elastic portion 222 can be compressed to different degrees, so that each clamping portion 221 can better adaptively clamp workpieces 500 of different sizes.

[0056] Specifically, the clamping member 220 includes a clamping portion 221 and an elastic portion 222 . The elastic portion 222 may be a spring. When the clamping portion 221 abuts against the workpiece 500 , the elastic portion 222 is compressed to facilitate adapting to the size of the workpiece 500 .

[0057] In other embodiments, the clamping and positioning device includes four clamping assemblies 200, and the four clamping assemblies 200 are distributed in a ring around the stage 110, that is, the angle between two adjacent clamping assemblies 200 can be set to 90°, and two adjacent clamping assemblies 200 of the four clamping assemblies 200 include a clamping portion 221 and an elastic portion 222, and the clamping portion 221 can abut against the elastic portion 222 in the horizontal direction, so as to provide clamping size adjustment in two different directions, and the other two adjacent clamping assemblies 200 are set as non-adjustable fixed structures, and the four clamping assemblies 200 clamp the workpiece 500 together in the horizontal direction. Specifically, the workpiece 500 can be square, and the workpiece 500 includes two pairs of clamped surfaces arranged opposite to each other, and the two pairs of clamped surfaces are clamped and positioned by a combination of fixed abutment on one side and elastic abutment on the other side. Compared with the clamping and fixing by elastic abutment at both ends, it is convenient to provide a positioning reference and effectively improve the positioning accuracy.

[0058] refer to Figures 2 to 5 In some embodiments, a guide block 120 is further provided on the base 100, and at least two first guide grooves 121 are provided on the guide block 120. Each clamping assembly 200 is correspondingly inserted into the first guide groove 121, that is, the number of the first guide grooves 121 is the same as the number of the clamping assemblies 200. The clamping assembly 200 slidably connected to the guide member 400 moves in the vertical direction and can simultaneously drive the guide block 120 to move. The guide block 120 can drive each clamping assembly 200 to move synchronously in the vertical direction. Since the guide block 120 is fixed on the base 100, it can also drive the base 100 and carry the driving assembly 300 to move in the vertical direction together, thereby avoiding relative displacement between the clamping assembly 200 and the driving assembly 300 in the vertical direction, and effectively ensuring the stability of the driving assembly 300 transmitting power to the clamping assembly 200.

[0059] It should be noted that each clamping assembly 200 is provided with a first rack 212, and the driving assembly 300 includes a gear 321. The driving assembly 300 transmits power to each clamping assembly 200 through the engagement of the gear 321 with the first rack 212. When each clamping assembly 200 moves in the vertical direction under the drive of the guide member 400, the driving assembly 300 can move in the vertical direction synchronously with each clamping assembly 200 to avoid the gear 321 and the second rack 311 from moving in the vertical direction, thereby ensuring the stability of the transmission.

[0060] refer to Figures 2 to 5 In other embodiments, a first guide groove 121 is provided on the guide block 120, and the number of the first guide grooves 121 and the clamping assembly 200 is the same. The driving assembly 300 includes a driving member 310 for providing power and a transmission member 320 for transmitting power. The guide block 120 is also provided with a receiving cavity for accommodating the transmission member 320. Each first guide groove 121 is communicated with the receiving cavity. Each clamping assembly 200 can be inserted into the first guide groove 121 one by one and be transmission-connected with the transmission member 320 located in the receiving cavity. The portion of each clamping assembly 200 that penetrates the first guide groove 121 can be provided with a first rack 212. The transmission member 320 can be a gear 321. Each clamping assembly 200 is transmission-connected to a different position of the transmission member 320. Thus, the relative position between each clamping assembly 200 and the transmission member 320 is determined, and the first guide groove 121 limits the movement of each clamping assembly 200 relative to the transmission member 320 in the vertical direction, which is beneficial to ensuring the stability of the transmission.

[0061] refer to Figure 5 and Figure 6In some embodiments, a limiting portion 122 is further provided on the guide block 120, and a second guide groove 211 is provided on the clamping assembly 200. The limiting portion 122 extends into the first guide groove 121 and is embedded in the second guide groove 211. When the clamping assembly 200 moves in the horizontal direction, the limiting portion 122 is embedded in the second guide groove 211 to limit the minimum distance between the main part of the clamping assembly 200 that is not provided with the first rack 212 and the transmission member 320 in the horizontal direction, which effectively avoids the collision between the main part of the clamping assembly 200 and the transmission member 320, and limits the minimum clamping size of the clamping positioning device, which is beneficial to ensuring the safety of clamping and positioning.

[0062] refer to Figures 7 to 9 In some embodiments, the guide member 400 includes a third guide groove 410, and the clamping assembly 200 is partially embedded in the third guide groove 410. The third guide groove 410 at least includes a first groove section 411 extending toward the worktable 110, and the extension direction of the first groove section 411 has an angle with the horizontal direction and the vertical direction. The clamping assembly 200 is configured to move in the horizontal direction while abutting against the groove wall of the third guide groove 410 to move in the vertical direction, that is, each clamping assembly 200 simultaneously includes movement in the horizontal direction and in the vertical direction when approaching or moving away from the workpiece 500.

[0063] Specifically, each clamping assembly 200 approaches or moves away from the workpiece 500 along the extension direction of the first groove section 411, the transmission member 320 can be a gear 321, and each clamping assembly 200 can be provided with a first rack 212 meshing with the transmission member 320. Through the meshing of the gear 321 and the first rack 212, the transmission member 320 can simultaneously drive each clamping assembly 200 to approach each other in the horizontal direction to clamp the workpiece 500. The third guide groove 410 also includes a second groove section 412. The first groove section 411 and the second groove section 412 are connected. The extension direction of the first groove section 411 is configured to have an angle with both the vertical direction and the horizontal direction. The extension direction of the first groove section 411 points to the worktable 110. The second groove section 412 extends in the horizontal direction. When the clamping assembly 200 approaches the workpiece 500, the pulley on the clamping assembly 200 slides from the first groove section 411 into the second groove section 412. When the clamping assembly 200 slides relatively in the first groove section 411, the first groove section 411 provides the clamping assembly 200 with partial displacement in the horizontal direction and in the vertical direction, so that the clamping assembly 200 exhibits a compound movement of rising in the vertical direction and approaching the workpiece 500 on the stage 110. When sliding to the second groove section 412, the second groove section 412 only provides support force in the vertical direction for the clamping assembly 200, so as to prevent the clamping assembly 200 from sliding in the vertical direction when clamping the workpiece 500, which is beneficial to ensure the stability of clamping.

[0064] It should be noted that a roller can be arranged on the clamping assembly 200 to roll in the third guide groove 410, which helps to increase the sliding smoothness between the clamping assembly 200 and the guide member 400, and the third guide groove 410 can be closed to prevent the roller on the clamping assembly 200 from detaching from the third guide groove 410, which is beneficial to ensure the stability of the sliding connection between the clamping assembly 200 and the sliding assembly.

[0065] refer to Figure 8 and Fig. 9 In some embodiments, the base 100 includes a first base frame 130 and a second base frame 140, the stage 110 and the guide member 400 are arranged on the first base frame 130, the driving assembly 300 and each clamping assembly 200 are arranged on the second base frame 140, each clamping assembly 200 includes a portion exposed to the first base frame 130, and the portion exposed to the first base frame 130 is used to clamp the workpiece 500. The first base frame 130 and the second base frame 140 are configured to realize the first base frame 130 through the sliding connection between the clamping assembly 200 and the guide member 400. The sliding connection between the first base 130 and the second base 140 enables each clamping assembly 200 to drive the first base 130 to slide in the vertical direction relative to the second base 140 when moving in the vertical direction, so that the driving assembly 300 and each clamping assembly 200 remain relatively fixed in the vertical direction, which is beneficial to ensuring the stability of the transmission between the driving assembly 300 and each clamping assembly 200 and extending the transmission life between the driving assembly 300 and each clamping assembly 200.

[0066] refer to Figure 8 In some embodiments, an elastic structure 141 is further provided on the second base frame 140. The second base frame 140 supports the first base frame 130 through the elastic structure 141. When the second base frame 140 slides in a vertical direction relative to the first base frame 130, the elastic structure 141 can provide a buffer for the relative sliding between the first base frame 130 and the second base frame 140.

[0067] refer to Figures 1 to 9According to the clamping and positioning device of the embodiment of the present application, at least the following method can be used to clamp and position the workpiece 500. Specifically, the workpiece 500 is first placed on the stage 110, and the driving member 310 drives the transmission member 320 to rotate relative to the second base frame 140. Each clamping assembly 200 slides relative to the second base frame 140 in a horizontal direction under the drive of the transmission member 320 to approach the workpiece 500. When each clamping assembly 200 slides relative to the second base frame 140 in a horizontal direction, at least two clamping assemblies 200 slide against the guide member 400, and the guide member 400 drives the clamping assembly 200 to move in a vertical direction and slide with the guide member 400. The dynamically connected clamping assembly 200 can simultaneously drive the second base frame 140 to move in the vertical direction, effectively avoiding relative movement between the clamping assembly 200 and the transmission member 320 in the vertical direction. When clamping the workpiece 500, each clamping assembly 200 includes movement in the horizontal direction and movement in the vertical direction. Different sizes of workpieces 500 can be clamped at different positions. When clamping the workpiece 500, the position of the clamping assembly 200 for clamping the workpiece 500 can also be provided with a clamping portion 221 and an elastic portion 222. The clamping portion 221 can compress the elastic portion 222 in the horizontal direction, which is beneficial for adapting to the clamping of workpieces 500 of different sizes.

[0068] In addition, the elastic structure 141 arranged on the second base frame 140 can provide a buffer for the relative movement between the first base frame 130 and the second base frame 140 in the vertical direction. Since the first base frame 130 and the second base frame 140 are connected to each other through the sliding connection between the clamping assembly 200 and the guide member 400, the elastic structure 141 can reduce the impact between the clamping assembly 200 and the guide member 400, thereby reducing the wear between the clamping assembly 200 and the guide member 400, which is beneficial to extending the service life of the clamping and positioning device.

[0069] refer to Figures 1 to 9 According to the second embodiment of the present application, the processing equipment includes a processing device and a clamping and positioning device according to any of the above embodiments. The processing device is equipped with a tool, and the processing device is used to drive the tool to process the workpiece 500 on the clamping and positioning device. The clamping and positioning device ensures the stability of the clamped workpiece 500, which is beneficial to ensure the processing accuracy of the processing equipment. In addition, the clamping and positioning device also improves the adaptability of clamping workpieces 500 of different sizes, avoids the need to replace the fixture or disassemble the clamping claws on the fixture due to changes in the workpiece 500, and effectively improves the processing efficiency of the processing equipment.
