[0028] The following is for reference. Figures 1 to 4 This invention describes a clamping fixture according to an embodiment of the present invention.

[0029] like Figures 1 to 3 As shown, the clamping fixture according to an embodiment of the present invention includes a main clamp 100 and an auxiliary clamp. The main clamp 100 is used to clamp one end of the product 500. The auxiliary clamp includes a clamping module 200, a positioning module 300, and an anti-slag sleeve module 400. The clamping module 200 includes a first driving component 210, a fixture plate 220, and a clamping component 230. The clamping component 230 is disposed on the fixture plate 220 and is used to assist in clamping the other end of the product 500. The first driving component... The output end of component 210 is connected to fixture plate 220 and is used to drive fixture plate 220 to move closer to or away from product 500; positioning module 300 is located on the side of fixture plate 220 and includes second drive component 310 and pressure claw 320. The output end of second drive component 310 is connected to pressure claw 320 and is used to drive pressure claw 320 to press or release fixture plate 220; anti-slag sleeve module 400 is located on the side of fixture plate 220 and is used to cover clamping module 200 to block waste.

[0030] Understandably, this clamping fixture includes a main clamp 100 and an auxiliary clamp. The main clamp 100 is used to clamp one end of the product 500, and the clamping module 200 in the auxiliary clamp is used to clamp the other end of the product 500. In use, the main clamp 100 first clamps one end of the product 500. Under the drive of the first drive component 210, the fixture plate 220 drives the clamping component 230 to move closer to the other end of the product 500. Subsequently, the pressure claw 320 in the positioning module 300, under the drive of the second drive component 310, presses the fixture plate 220, thereby achieving the clamping of the fixture plate 220. The anti-slag sleeve module 400 is then placed over the product 500, and the clamping component 230 clamps the other end of the product 500, thereby achieving a firm lock on both ends of the product 500. Subsequently, the cutting tool can perform high-precision cutting and other processing on the product 500. During the processing, due to the protective function of the anti-slag sleeve module 400, the clamping module 200 is protected from pollution by waste residue during processing, improving the environmental protection level of the processing process. Therefore, the clamping fixture of this application has the advantages of stable clamping, improved CNC machining quality, and clean processing.

[0031] It is understood that the clamping assembly 230 includes a third drive assembly 231, a wedge assembly 232, and a gripper assembly 233. The gripper assembly 233 is rotatably connected to the jig plate 220 and located on the side of the wedge assembly 232 near the main jig 100. The wedge assembly 232 has a first guide surface 2321, and the gripper assembly 233 has a second guide surface 2331. The output end of the third drive assembly 231 is connected to the wedge assembly 232 and is used to drive the first guide surface 2321 of the wedge assembly 232 to abut against or move away from the second guide surface 2331 of the gripper assembly 233, so that the gripper assembly 233 clamps or releases the product 500. For example, as Figure 4 As shown, in this embodiment, driven by the third drive component 231, the wedge component 232 can abut against or move away from the gripper component 233, so that the first guide surface 2321 can abut against the second guide surface 2331, thereby enabling the clamping component 230 to clamp or release the product 500.

[0032] It is understandable that both the first guide surface 2321 and the second guide surface 2331 are guide ramps. For example, as... Figure 4 As shown, in this embodiment, both the first guide surface 2321 and the second guide surface 2331 are guide slopes; in other embodiments, both the first guide surface 2321 and the second guide surface 2331 can be set as guide curved surfaces.

[0033] It is understood that the clamping assembly 230 includes an elastic element connected to the gripper assembly 233 and used to provide an elastic force for the gripper assembly 233 to open near the main clamp 100. For example, in this embodiment, the gripper assembly 233 can remain open near the main clamp 100 under the action of the elastic element, while under the drive of the third drive assembly 231, the gripper assembly 233 can remain clamped near the main clamp 100 to achieve clamping of the product 500.

[0034] It is understood that the clamping assembly 230 includes a connecting plate 235, and multiple sets of wedge-shaped assemblies 232 and gripper assemblies 233 are respectively provided and are arranged in a one-to-one correspondence. The connecting plate 235 connects the output end of the third drive assembly 231 and the wedge-shaped assembly 232. For example, as Figure 4 As shown, in this embodiment, the third drive component 231 can simultaneously drive multiple wedge components 232 to abut against the gripper component 233 through the connecting plate 235, thereby achieving simultaneous clamping of multiple products 500.

[0035] It is understood that the clamping assembly 230 includes a mounting plate 236, which includes a mounting portion 2361 and a guide portion 2362 connected to each other. The mounting portion 2361 connects the fixture plate 220 and the gripper assembly 233. The guide portion 2362 is provided with multiple guide holes, and the wedge-shaped assembly 232 passes through the guide portion 2362 and moves along the through direction of the guide holes. For example, as Figure 4 As shown, in this embodiment, the gripper assembly 233 is disposed on the mounting portion 2361 of the mounting plate 236, and the wedge assembly 232 achieves linear motion through the guide portion 2362, thereby improving the linearity of the movement of the wedge assembly 232.

[0036] It should be understood that the gripper assembly 233 is also provided with a partition block 234. The gripper assembly 233 consists of two levers rotatably connected to the mounting plate 236. The partition block 234 is located between the two levers. An elastic element passes through the partition block 234 and connects the two levers, and is used to provide an elastic force that moves the ends of the levers close to the main clamp 100 away from each other.

[0037] It should be understood that the gripper assembly 233 is covered with a cover plate 238, which also serves to separate waste residue.

[0038] It is understood that the clamping assembly 230 includes a plurality of spacers 237, which are disposed between adjacent gripper assemblies 233. For example, as Figure 4 As shown, in this embodiment, by providing a partition 237 between adjacent gripper assemblies 233, the movement between them is blocked, so as to avoid the movement of each other affecting each other.

[0039] It is understood that the slag-prevention module 400 includes a fourth drive assembly 410 and a slag-prevention cover 420. The output end of the fourth drive assembly 410 is connected to the slag-prevention cover and used to drive the slag-prevention cover to rise and fall. For example, as Figure 2 As shown, in this embodiment, the slag cover is raised and lowered by the drive of the fourth drive component 410, thereby preventing waste chips generated during the processing of product 500 from flying into the clamping component 230 and affecting the processing, thus improving the cleanliness of the processing.

[0040] It is understood that the clamping module 200 also includes a receiving frame 240, which is fixed to the jig plate 220 and located below the gripper assembly 233. For example, as Figures 2 to 3 As shown, in this embodiment, the jig plate 220 is also provided with a receiving frame 240 located below the gripper assembly 233, so that after the product 500 is cut, the end of the product 500 near the gripper assembly 233 can fall into the receiving frame 240, which facilitates automatic collection.

[0041] Understandably, it also includes a worktable 600 and a guide rail 610, with the guide rail 610 located on the worktable 600 and the fixture plate 220 slidably connected to the guide rail 610. For example, as... Figures 1 to 2 As shown, in this embodiment, the jig plate 220 is mounted on the worktable 600 via the guide rail 610, thereby improving the linearity of the jig plate 220's movement and improving the accuracy of the gripper assembly 233 in holding the product 500.

[0042] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
