This facilitates the positioning and clamping of the product without causing damage, and can fix the product's position at a low cost. Therefore, it achieves the technical effects of being less prone to damage, being able to fix the position, and being cost-effective. Attached Figure Description

Detailed Implementation

[0028] This invention discloses a clamping device. A first clamping end 31 in a first clamping mechanism 3 is slidably disposed in a first inclined guide groove 11 of a housing 1, and a first connecting end 32 connecting the first clamping end 31 is connected to a driving assembly. In each second clamping mechanism 4, a second clamping end 41 is slidably disposed in a corresponding second inclined guide groove 12 in the housing 1, and a second connecting end 42 connecting the second clamping end 41 is slidably disposed in a corresponding sliding groove 321 in the first connecting end 32. The first clamping end 31 and multiple second clamping ends 41 enclose a clamping area 44. The driving assembly drives the first connecting end 32 to move the first clamping end 31 and multiple second clamping ends 41 closer together or further apart. During the process of fixing the product with a triangular prism structure, the drive assembly drives the first connecting end 32 to descend, causing the first clamping end 31 and multiple second clamping ends 41 to move closer together. The approaching first clamping end 31 and multiple second clamping ends 41 clamp the product from all sides within the clamping area 44, thus fixing the product within the clamping area 44. Then, the drive assembly drives the first connecting end 32 to descend, causing the first clamping end 31 and multiple second clamping ends 41 to move away from each other. At this point, the first clamping end 31 and multiple second clamping ends 41 are away from the product within the clamping area 44, releasing the product. This facilitates product positioning and clamping without causing damage, effectively fixing the product's position at a low cost. Thus, it achieves the technical effects of being less prone to damage, effectively fixing the position, and being cost-effective.

Figure 2 , Figure 8 This is a schematic diagram of the clamping area 44 in a clamping device according to an embodiment of the present invention. The clamping device provided in this embodiment includes a housing 1 having at least one first inclined guide groove 11 and a plurality of second inclined guide grooves 12, a drive assembly, a first clamping mechanism 3, and a number of second clamping mechanisms 4 equal to the number of the plurality of second inclined guide grooves 12. The housing 1, the drive assembly, the first clamping mechanism 3, and the second clamping mechanism 4 will now be described in detail below:

[0034] For shell 1:

[0035] The housing 1 has at least one first inclined guide groove 11 and a plurality of second inclined guide grooves 12. The housing 1 may further include a receiving cavity 13 communicating with one of the first inclined guide grooves 11 and the plurality of second inclined guide grooves 12 respectively. The first inclined guide groove 11 and the plurality of second inclined guide grooves 12 are radially distributed relative to the receiving cavity 13. The number of the plurality of second inclined guide grooves 12 is two, and the distance between the two second inclined guide grooves 12 and the first inclined guide groove 11 is equal. The two second inclined guide grooves 12 and the two second clamping ends 41 described below are arranged in a one-to-one correspondence.

[0036] Specifically, the first inclined guide groove 11 in the housing 1 has a space to accommodate the first clamping end 31 of the first clamping mechanism 3 described below. The inner wall of the first inclined guide groove 11 is inclined, and the first clamping end 31 can slide up and down along the inner wall of the first inclined guide groove 11. The accommodating cavity 13 in the housing 1 is connected to the first inclined guide groove 11 and the second inclined guide groove 12 respectively. The accommodating cavity 13 has a space to accommodate the push rod 211, the first connecting end 32, and the second connecting end 42 described below. Multiple second inclined guide grooves 12 can refer to 1 second inclined guide groove 12, 2 second inclined guide grooves 12, 3 second inclined guide grooves 12, etc. When there are 2 second inclined guide grooves 12, the number of sliding grooves 321 described below is 2, and the number of second clamping mechanisms 4 described below is also 2. The 2 second inclined guide grooves 12 and 1 first inclined guide groove 11 can press the product with a triangular prism structure, which is hereinafter referred to as the product to be processed 6. The interior of the second inclined guide groove 12 has a space to accommodate the second clamping end 41 in the second clamping mechanism 4 described below. The inner wall of the second inclined guide groove 12 is inclined, and the second clamping end 41 can slide up and down along the inner wall of the second inclined guide groove 12.

[0037] For driver components:

[0038] The drive assembly includes a drive device 21 and a solenoid valve 22 connected to the drive device 21. The push rod 211 of the drive device 21 passes through the accommodating cavity 13 and is detachably connected to the first connecting end 32.

[0039] Specifically, in the drive assembly, the drive component 21 is detachably connected to the first connecting end 32 of the first clamping mechanism 3 via a push rod 211. For example, if the portion of the push rod 211 near the first connecting end 32 is T-shaped, a snap-fit ​​groove 322 matching the T-shaped push rod 211 is provided in the first connecting end 32. After the T-shaped push rod 211 is inserted into the snap-fit ​​groove 322 from one side of the first connecting end 32, the push rod 211 can be detachably connected to the first connecting end 32, facilitating the assembly and disassembly of the first clamping mechanism 3. The drive component 21 can be a cylinder or a motor. If the drive component 21 is a cylinder, it is connected to a solenoid valve 22 via an air inlet pipe and an air outlet pipe, respectively. The solenoid valve 22 is connected to a push button switch 23. After activating the push button switch 23, the solenoid valve 22 controls the drive component 21 to start working. The drive component 21 pulls the first connecting end 32 and the first clamping end 31 connected to the first connecting end 32 downwards via the push rod 211. This means that a single driving device 21 can move the first connecting end 32 and the first clamping end 31, which helps to reduce costs.

[0040] For the first clamping mechanism 3:

[0041] The first clamping mechanism 3 includes a first clamping end 31 and a first connecting end 32 connected to the first clamping end 31. The first clamping end 31 is slidably disposed in the first inclined guide groove 11. The first connecting end 32 is connected to the driving assembly. The first connecting end 32 is provided with a number of sliding grooves 321 equal to the number of the plurality of second inclined guide grooves 12. The first clamping end 31 includes a first clamping member 311 and a first clamping block 312 disposed in the first clamping member 311. The first clamping block 312 is provided with a first inclined surface 3121 at one end near the clamping area 44. The first clamping member 311 is slidably disposed in the first inclined guide groove 11. The first clamping block 312 is provided with a first arcuate groove 3122 connecting the first inclined surface 3121. The first clamping member 311 is provided with a second arcuate groove 3111 connecting the first arcuate groove 3122. The first clamping member 311 is provided with a first positioning pin, and the first clamping block 312 is provided with a first positioning hole 3123 for the first positioning pin to pass through. The first clamping mechanism 3 also includes a first locking member 33, which passes through the first clamping block 312 and is connected to the first clamping end 31.

[0042] Specifically, the first connecting end 32 of the first clamping mechanism 3 may be provided with two sliding grooves 321. The interior of the sliding grooves 321 has space to accommodate the second connecting end 42 of the second clamping mechanism 4 described below, and the second connecting end 42 can slide inside the sliding grooves 321. The first clamping member 311 of the first clamping end 31 is integrally formed with the first connecting end 32. A first clamping block 312 connected by a first locking member 33 is provided on the first clamping member 311. The first positioning pin may refer to a locking screw. The first positioning pin located on the first clamping member 311 can pass through the first positioning hole 3123 located on the first clamping block 312. By passing the first positioning pin through the first positioning hole 3123 in the first clamping block 312, the installation position of the first clamping block 312 can be fixed. A first inclined surface 3121 matching the product 6 to be processed is provided on the first clamping block 312. The first inclined surface 3121 contacts the product 6 to be processed to achieve clamping on one side of the product 6 to be processed. By connecting the first locking member 33 to the first positioning pin and the first clamping block 312 respectively, it is convenient to select the corresponding shape of the first clamping block 312 according to the size and shape of the product 6 to be clamped, so as to easily replace and install the first clamping block 312 and adapt to clamping products 6 of different sizes and shapes. Since the edge of the bottom of the product 6 is easily damaged after being subjected to greater pressure, in order to avoid the first clamping block 312 directly contacting the easily damaged bottom edge, after the first arc-shaped groove 3122 on the first clamping block 312 and the second arc-shaped groove 3111 on the first clamping member 311 are enclosed to form an arc-shaped groove, the opening of the arc-shaped groove facing the product 6 to be processed will have space to accommodate the bottom edge of the product 6, so that the first clamping block 312 will not directly press on the bottom edge, and the product 6 to be processed will not be easily damaged when fixing its position.

[0043] For the second clamping mechanism 4:

[0044] The number of second clamping mechanisms 4 is the same as the number of second inclined guide grooves 12. Each second clamping mechanism 4 includes a second clamping end 41 and a second connecting end 42 connected to the second clamping end 41. The second clamping end 41 is slidably disposed in the corresponding second inclined guide groove 12, and the second connecting end 42 is slidably disposed in the corresponding slide groove 321. The first clamping end 31 and the plurality of second clamping ends 41 surround to form a clamping area 44, so that the first connecting end 32 can be driven to rise and fall by the driving component to drive the first clamping end 31 and the plurality of second clamping ends 41 to move closer or further away from each other. Each of the second clamping ends 41 includes a second clamping member 411 and a second clamping block 412 disposed on the second clamping member 411. The second clamping block 412 has a second inclined surface 4121 at one end near the clamping area 44. The second clamping member 411 is slidably disposed in the second inclined guide groove 12. The first inclined surface 3121 and multiple second inclined surfaces 4121 surround the clamping area 44, which has an interior space capable of accommodating the product 6 to be processed. Each second clamping block 412 is provided with a third arc-shaped groove 4122 connecting to the second inclined surface 4121, and the corresponding second clamping member 411 is provided with a fourth arc-shaped groove 4111 connecting to the third arc-shaped groove 4122. A second positioning pin is provided on the second clamping member 411, and a second positioning hole is provided on the second clamping block 412 for the second positioning pin to pass through. The second clamping mechanism 4 may further include a plurality of second locking members, each of which passes through the corresponding second clamping block 412 and is connected to the second clamping end 41. The second clamping end 41 slides along the length extension direction of the corresponding second inclined guide groove 12. The second clamping end 41 and the corresponding second connecting end 42 are integrally formed. One second connecting end 42 is provided with a groove 421 that matches the corresponding slide groove 321. The two sides of the other second connecting end 42 are respectively slidably disposed in the groove 421 and the corresponding slide groove 321. The clamping device provided in this embodiment of the invention may further include a support frame 5. The drive assembly and the housing 1 are respectively mounted on the support frame 5. The support frame 5 is provided with an opening 51, which communicates with the receiving cavity 13. The support frame 5 is configured to provide support for the housing 1 and the drive assembly. The push rod 211 of the drive assembly extends into the receiving cavity 13 through the opening 51 in the support frame 5 and is connected to the first connecting end 32.

[0045] Specifically, since the second clamping member 411 of the second clamping end 41 in the second clamping mechanism 4 has the same structure and principle as the first clamping member 311 mentioned above, it will not be described again here. Since the second clamping block 412 has the same structure and principle as the first clamping block 312 mentioned above, it will not be described again here. Since the second inclined surface 4121 has the same structure and principle as the first inclined surface 3121 mentioned above, it will not be described again here. Since the third arc-shaped groove 4122 located in the second clamping block 412 has the same structure and principle as the first arc-shaped groove 3122 located in the first clamping block 312, it will not be described again here. Since the fourth arc-shaped groove 4111 located in the second clamping member 411 has the same structure and principle as the second arc-shaped groove 3111 located in the first clamping member 311, it will not be described again here. Since the second positioning pin has the same structure and principle as the first positioning pin mentioned above, it will not be described again here. Since the second locking member has the same structure and principle as the first locking member 33 mentioned above, it will not be described again here.

[0046] It is worth mentioning that, assuming the two sliding grooves 321 located at the first connecting end 32 of the first clamping mechanism 3 are, from bottom to top, the first sliding groove 321 and the second sliding groove 321. When there are two second clamping mechanisms 4, assuming the two second clamping mechanisms 4 are the second clamping mechanism 4A and the second clamping mechanism 4B respectively, the second clamping mechanism 4A is as follows: Figure 6 As shown, the second clamping mechanism 4B is as follows: Figure 7As shown, the second connecting end 42 of the second clamping mechanism 4A is provided with a groove 421 that matches the second sliding groove 321. The groove 421 and the second sliding groove 321 are aligned with each other. The second sliding groove 321 has space to accommodate one side of the second connecting end 42 of the second clamping mechanism 4B for sliding, and the groove 421 has space to accommodate the other side of the second connecting end 42 of the second clamping mechanism 4B for sliding. A limiting block 322 can also be provided above the second sliding groove 321 in the first connecting end 32 for limiting the second connecting end 42 of the second clamping mechanism 4B. The limiting block 322 can limit the vertical position of the second connecting end 42 of the second clamping mechanism 4B to prevent the second connecting end 42 of the second clamping mechanism 4B from falling out of the second sliding groove 321. By embedding the protruding part of the bottom of the second connecting end 42 of the second clamping mechanism 4A into the first sliding groove 321, the second connecting end 42 of the second clamping mechanism 4A can slide within the first sliding groove 321. After the product 6 to be processed is placed inside the clamping area 44, the drive component 21 in the drive assembly drives the push rod 211 to pull the first connecting end 32 downward. The downward movement of the first connecting end 32 will drive the second clamping mechanism 4A and the second clamping mechanism 4B to move downward together. At this time, the second clamping block 412 in the second clamping mechanism 4A, the second clamping block 412 in the second clamping mechanism 4B, and the first clamping block 312 will gradually move towards the product 6 to be processed, thereby clamping the product 6 to be processed. Alternatively, the drive component 21 in the drive assembly drives the push rod 211 to pull the first connecting end 32 upward. The upward movement of the first connecting end 32 will drive the second clamping mechanism 4A and the second clamping mechanism 4B to move upward together. At this time, the second clamping block 412 in the second clamping mechanism 4A, the second clamping block 412 in the second clamping mechanism 4B, and the first clamping block 312 will gradually move away from the product 6 to be processed, thereby releasing the clamped product 6 to be processed. It should be noted that when only the two sides of the product 6 to be processed need to be clamped, the aforementioned plurality of second inclined guide grooves 12 can be replaced by one second inclined guide groove 12, and the number of second clamping mechanisms 4 is also one. In this case, the drive assembly can drive the second clamping block 412 and the first clamping block 312 to clamp the product 6 to be processed from both sides. When the product 6 to be processed has a hexagonal structure and all six sides of the product 6 to be processed need to be clamped, the aforementioned plurality of second inclined guide grooves 12 can be replaced by five second inclined guide grooves, and the number of second clamping mechanisms 4 is also five. In this case, the same principle as the two second clamping mechanisms 4 mentioned above is used, and the drive assembly can drive the five second clamping blocks 412 and one first clamping block 312 to clamp the product 6 to be processed from all six sides.

[0047] This invention provides a clamping device. A first clamping end 31 in a first clamping mechanism 3 is slidably disposed in a first inclined guide groove 11 of a housing 1, and a first connecting end 32 connecting the first clamping end 31 is connected to a driving assembly. In each second clamping mechanism 4, a second clamping end 41 is slidably disposed in a corresponding second inclined guide groove 12 in the housing 1, and a second connecting end 42 connecting the second clamping end 41 is slidably disposed in a corresponding groove 321 in the first connecting end 32. The first clamping end 31 and multiple second clamping ends 41 enclose a clamping area 44. The driving assembly drives the first connecting end 32 to move the first clamping end 31 and multiple second clamping ends 41 closer together or further apart. During the process of fixing the product with a triangular prism structure, the drive assembly drives the first connecting end 32 to descend, causing the first clamping end 31 and multiple second clamping ends 41 to move closer together. The approaching first clamping end 31 and multiple second clamping ends 41 clamp the product from all sides within the clamping area 44, thus fixing the product within the clamping area 44. Then, the drive assembly drives the first connecting end 32 to descend, causing the first clamping end 31 and multiple second clamping ends 41 to move away from each other. At this point, the first clamping end 31 and multiple second clamping ends 41 are away from the product within the clamping area 44, releasing the product. This facilitates product positioning and clamping without causing damage, effectively fixing the product's position at a low cost. Thus, it achieves the technical effects of being less prone to damage, effectively fixing the position, and being cost-effective.

[0048] To provide a detailed description of the clamping method provided by the present invention, the above embodiment 1 provides a detailed description of a clamping device. Based on the same inventive concept, this application also provides a clamping method, as detailed in embodiment 2.

[0049] Example 2

[0050] Embodiment 2 of the present invention provides a clamping method, including placing the product to be processed 6 in a clamping area 44; using a driving component to drive the first connecting end 32 to descend so as to move the first clamping end 31 and a plurality of second clamping ends 41 closer together to clamp the product to be processed 6; using a driving component to drive the first connecting end 32 to rise so as to move the first clamping end 31 and a plurality of second clamping ends 41 further apart to release the product to be processed 6.

[0051] This invention provides a clamping method in which the product 6 to be processed is placed in a clamping area 44; a driving component drives the first connecting end 32 to descend, causing the first clamping end 31 and multiple second clamping ends 41 to move closer together to clamp the product 6; the driving component then drives the first connecting end 32 to rise, causing the first clamping end 31 and multiple second clamping ends 41 to move away from each other to release the product 6. In this process of fixing the position of the triangular-prism structured product, the driving component drives the first connecting end 32 to descend, causing the first clamping end 31 and multiple second clamping ends 41 to move closer together. The approaching first clamping ends 31 and multiple second clamping ends 41 clamp the product from around the product within the clamping area 44, thus fixing the product within the clamping area 44. Then, the driving component drives the first connecting end 32 to descend, causing the first clamping end 31 and multiple second clamping ends 41 to move away from each other. At this time, the first clamping ends 31 and multiple second clamping ends 41 move away from the product within the clamping area 44, thus releasing the product. This facilitates product positioning and clamping without causing damage, effectively fixing the product's position at a lower cost. Thus, it achieves the technical benefits of minimizing product damage, ensuring stable positioning, and reducing costs.

[0052] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
