Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a 360° rotating machining device. Background Technology

[0002] Currently, in the CNC machining industry, products are often processed from different angles, which means that some products cannot be processed in one go and require additional processes to complete the processing. This also requires additional machines and operators, resulting in low production efficiency and increased production costs.

[0003] Among existing patents, Chinese patent application number 202122862568.2 discloses a clamping and rotating structure for machining automotive drive shafts, including a clamping structure. The clamping structure includes a support base, with a left mounting bracket and a right mounting bracket respectively provided on the left and right sides of the upper end of the support base. A sliding limit groove is provided on the right side of the upper end of the support base, and the right mounting bracket is slidably engaged with the sliding limit groove. The left mounting bracket is fixedly connected to the support base. A side adjustment turntable is provided on the right side of the support base. A hydraulic chuck is rotatably engaged inside the right mounting bracket. Side engagement grooves are provided on both sides of the right mounting bracket, and side rotating bearings are fixedly connected inside the two side engagement grooves. The inner ring surface of the side rotating bearing is fixedly connected to the outer surface of the hydraulic chuck. A hydraulic rotating chuck is rotatably connected inside the left mounting bracket, and clamping claws are provided on the right side and the left side of the hydraulic rotating chuck.

[0004] Furthermore, Chinese patent application number 202223384460.8 discloses a clamping and rotating device for pipe fitting processing, characterized in that it includes a rotatable pneumatic three-jaw chuck, the rear end of which is coaxially connected to a rotary motor that drives its rotation via a pneumatic slip ring, the rotary motor being mounted on a motor mounting plate, the rotating shaft of the rotary motor being rotatably mounted on a support plate, the support plate being arranged parallel to and spaced apart from the mounting plate and vertically mounted on a movable plate, the movable plate being connected to a linear drive mechanism and being driven to move linearly back and forth along the axial direction of the rotary motor.

[0005] Furthermore, Chinese patent application number 201720316631.3 discloses a four-axis automatic clamping device for a CNC machining center, comprising a worktable, a rotary four-axis, a rotary cylinder, a tie rod, a hollow hydraulic chuck, a transition plate, and jaws. The rotary four-axis is fixed above the worktable. The rotary cylinder is connected to the rotary four-axis by screws and can rotate with the rotary four-axis. The tie rod passes through the rotary four-axis and the transition plate, with its front end connected to the hollow hydraulic chuck and its rear end connected to the rotary cylinder. The hollow hydraulic chuck has three jaws at its front end and its rear end connected to the tie rod, allowing the hollow hydraulic chuck to rotate under the drive of the tie rod. The transition plate is positioned between the rotary four-axis and the hollow hydraulic chuck.

[0006] The aforementioned patent documents all use chucks (grippers) to hold the end periphery of the product, which obstructs the end periphery of the product, preventing the cutting tool from machining the end periphery of the product. This results in at least two clamping operations required to machine the end periphery of the product, increasing the number of clamping and tool setting operations, making the operation cumbersome, inefficient, and increasing the labor intensity of the operators.

[0007] Therefore, the defects are very obvious, and a solution is urgently needed. Utility Model Content

[0008] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a 360° rotating processing device.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A 360° rotating machining device includes a worktable, an indexing plate module mounted on the worktable, a carrier mounted on the front of the turntable of the indexing plate module and located above the worktable, a clamping driver mounted on the rotating shaft of the indexing plate module, a pull rod that slides through the carrier and the rotating shaft of the indexing plate module, and a clamping block rotatably connected to one end of the pull rod and located in front of the carrier. The clamping driver is located on the back of the indexing plate module, and the other end of the pull rod is connected to the driving end of the clamping driver. The clamping driver is used to drive the pull rod to reciprocate.

[0011] Furthermore, a rotating groove is provided at one end of the pull rod, and the middle part of the clamping block is rotatably connected to the open end of the rotating groove, so that one end of the clamping block can rotate into the rotating groove.

[0012] Furthermore, the middle part of the clamping block is rotatably connected to the inner wall of the opening end of the rotating groove via a rotating rod.

[0013] Furthermore, a positioning post protrudes from one side of the bottom wall of the rotating groove, and the rotation axis of the clamping block and the rotating groove is offset from the positioning post; when the end face of the positioning post abuts against the side of the clamping block, the clamping block and the pull rod are set at an angle.

[0014] Furthermore, the end face of the positioning column is the reference plane, and the side of the clamping block is the positioning plane; when the reference plane and the positioning plane are in contact, the pull rod is set perpendicular to the clamping block.

[0015] Furthermore, when one end of the clamping block rotates into the rotating groove, the positioning plane of the clamping block abuts against the inner wall of the positioning column, and the central axis of the clamping block is parallel to the central axis of the pull rod.

[0016] Furthermore, the carrier includes a mounting plate installed on the front of the indexing plate module's turntable and a positioning part disposed on the mounting plate and coaxially disposed with the turntable of the indexing plate module, with the pull rod coaxially disposed with the positioning part.

[0017] Furthermore, the positioning part includes a fixing block fixedly connected to the mounting plate and a sleeve protruding from the front of the fixing block, with a limiting step formed between the fixing block and the sleeve.

[0018] Furthermore, the worktable is provided with an adjustment groove, the cross-sectional shape of which is convex. A locking nut is slidably installed in the adjustment groove, and a locking bolt is detachably connected to the base of the indexing plate module. The locking bolt is used for threaded connection with the locking nut.

[0019] Furthermore, the clamping driver includes a pad mounted on the rotating shaft of the indexing plate module and a cylinder mounted on the pad. The piston rod of the cylinder slides through the pad and is coaxially connected to the pull rod.

[0020] The beneficial effects of this utility model are as follows: In practical applications, the clamping block is first rotated to a state approximately in line with the pull rod. Then, the center hole of the product is passed through the clamping block and the pull rod and placed on the carrier. Next, the clamping block is rotated to a state approximately perpendicular to the pull rod. Then, the clamping driver drives the pull rod and the clamping block to move backward, so that the clamping block moves closer to the end face of the product until the clamping block engages with the carrier to clamp the product. The carrier and the clamping block respectively abut against the two end faces of the product, and the machine tool can then process the product. After the tool completes the processing of one angle face of the product, the indexing plate module is controlled by the program to drive the carrier, along with the product, the clamping driver, the pull rod, and the clamping block, to rotate synchronously by a preset angle, allowing the product to rotate 360°, thus enabling 360° processing of the product. After processing is completed, the clamping driver drives the pull rod and the clamping block to move forward and reset to release the processed product. Then, the clamping block is rotated to a state approximately in line with the pull rod, at which point the processed product can be removed, and the product to be processed is then placed on the carrier. This invention has a simple structure and low cost. It can automatically clamp the product and drive it to rotate 360°. The product can be processed 360° in one clamping. It is easy to operate, reduces the labor intensity of operators, and improves the product processing yield. Attached Figure Description

[0028] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0029] like Figures 1 to 5 As shown, the present invention provides a 360° rotating machining device, which includes a worktable 1, an indexing plate module 2 mounted on the worktable 1, a carrier 3 mounted on the front of the turntable of the indexing plate module 2 and located above the worktable 1, a clamping driver 4 mounted on the rotating shaft of the indexing plate module 2, a pull rod 5 that slides through the carrier 3 and the rotating shaft of the indexing plate module 2, and a clamping block 6 rotatably connected to one end of the pull rod 5 and located in front of the carrier 3. The clamping driver 4 is located on the back of the indexing plate module 2, and the other end of the pull rod 5 is connected to the driving end of the clamping driver 4. The clamping driver 4 is used to drive the pull rod 5 to reciprocate. Specifically, the indexing plate module 2 is a CNC indexing plate, and the product 18 has a center hole.

[0030] In practical applications, the clamping block 6 is first rotated to a position roughly in line with the pull rod 5. Then, the center hole of the product 18 is passed through the clamping block 6 and the pull rod 5 and fitted onto the carrier 3. Next, the clamping block 6 is rotated to a position roughly perpendicular to the pull rod 5. Then, the clamping driver 4 drives the pull rod 5 and the clamping block 6 to move backward, so that the clamping block 6 moves closer to the end face of the product 18 until the clamping block 6 cooperates with the carrier 3 to clamp the product 18. The carrier 3 and the clamping block 6 respectively abut against the two end faces of the product 18, and the machine tool can then process the product 18. After the tool completes the processing of one angle face of the product 18, the indexing plate module 2 is controlled by the program to drive the carrier 3, along with the product 18, the clamping driver 4, the pull rod 5, and the clamping block 6, to rotate synchronously by a preset angle, so that the product 18 can rotate 360°, thereby enabling 360° processing of the product 18. After processing, the clamping driver 4 drives the pull rod 5, along with the clamping block 6, to move forward and reset, releasing the processed product 18. Then, the clamping block 6 is rotated until it is approximately in a straight line with the pull rod 5, at which point the processed product 18 can be removed. The product to be processed, 18, is then placed on the carrier 3. This invention has a simple structure and low cost, enabling automatic clamping of the product 18 and driving it to rotate 360°. A single clamping operation allows for 360° processing of the product 18, making operation convenient, reducing the labor intensity of operators, and improving the yield rate of the processed product 18.

[0031] In this embodiment, a rotating groove 7 is provided at one end of the pull rod 5, and the middle part of the clamping block 6 is rotatably connected to the open end of the rotating groove 7, so that one end of the clamping block 6 can rotate into the rotating groove 7. The rotating groove 7 not only provides space for the clamping block 6 to rotate relative to the pull rod 5, but also accommodates one end of the clamping block 6, so that the clamping block 6 can rotate to a state that is approximately in the same straight line or perpendicular to the pull rod 5.

[0032] In this embodiment, the middle part of the clamping block 6 is rotatably connected to the inner wall of the opening end of the rotating groove 7 via the rotating rod 8. This structural design facilitates the assembly of the clamping block 6 and the pull rod 5, and improves the rotational stability of the clamping block 6 at the opening end of the rotating groove 7.

[0033] In this embodiment, a positioning post 9 protrudes from one side of the bottom wall of the rotating groove 7, and the rotation axis of the clamping block 6 and the rotating groove 7 is offset from that of the positioning post 9; when the end face of the positioning post 9 abuts against the side of the clamping block 6, the clamping block 6 and the pull rod 5 are set at an angle. When the clamping block 6 rotates to the point where the pull rod 5 is set to clamp the clamping block 6, the positioning post 9 positions the clamping block 6 to prevent the clamping block 6 from rotating excessively or arbitrarily.

[0034] In this embodiment, the end face of the positioning post 9 is a reference plane, and the side face of the clamping block 6 is a positioning plane; when the reference plane and the positioning plane abut, the pull rod 5 is perpendicular to the clamping block 6. This structural design allows the clamping block 6 to rotate to a state perpendicular to the pull rod 5, which is beneficial for stably clamping the product 18 on the carrier 3.

[0035] In this embodiment, when one end of the clamping block 6 rotates into the rotating groove 7, the positioning plane of the clamping block 6 abuts against the inner wall of the positioning post 9, and the central axis of the clamping block 6 is parallel to the central axis of the pull rod 5; preferably, the central axis of the clamping block 6 coincides with the central axis of the pull rod 5. When the clamping block 6 rotates to be coaxial with the pull rod 5, the inner wall of the positioning post 9 abuts against the positioning plane of the clamping block 6 to position the clamping block 6 and ensure the stability of the clamping block 6.

[0036] In this embodiment, the carrier 3 includes a mounting plate 10 installed on the front of the turntable of the indexing plate module 2 and a positioning part 11 disposed on the mounting plate 10 and coaxially disposed with the turntable of the indexing plate module 2. The pull rod 5 is coaxially disposed with the positioning part 11. In practical applications, the center hole of the product 18 is sleeved outside the positioning part 11, so that the carrier 3 supports the product 18.

[0037] In this embodiment, the positioning part 11 includes a fixing block 12 fixedly connected to the mounting plate 10 and a sleeve post 13 protruding from the front of the fixing block 12, with a limiting step 14 formed between the fixing block 12 and the sleeve post 13. In practical applications, the center hole of the product 18 is fitted onto the sleeve post 13, and the inner end face of the product 18 abuts against the limiting step 14 to limit the product 18 and ensure that the product 18 can be stably and accurately fitted onto the sleeve post 13.

[0038] In this embodiment, the worktable 1 has an adjustment groove 15 with a convex cross-sectional shape. A locking nut is slidably disposed within the adjustment groove 15. A locking bolt 19 is detachably connected to the base of the indexing plate module 2, and the locking bolt 19 is threadedly connected to the locking nut. When the indexing plate module 2 is fixedly installed on the worktable 1, the stud of the locking bolt 19 extends into the adjustment groove 15 and is threadedly connected to the locking nut. When it is necessary to adjust the position of the indexing plate module 2 on the worktable 1, the locking bolt 19 is loosened, allowing the indexing plate module 2 to be adjusted relative to the worktable 1 along the length of the adjustment groove 15. After adjustment, the locking bolt 19 and the locking nut are tightened together.

[0039] In this embodiment, the clamping driver 4 includes a pad 16 mounted on the rotating shaft of the indexing plate module 2 and a cylinder 17 mounted on the pad 16. The piston rod of the cylinder 17 slides through the pad 16 and is coaxially connected to the pull rod 5. In practical applications, the piston rod of the cylinder 17 extends and retracts to drive the pull rod 5 and the clamping block 6 to move back and forth.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
