Description

Technical Field

[0001] This application relates to the field of machining technology, specifically to a clamping jaw cutting fixture and its usage method. Background Technology

[0002] In machining, the manufacture of clamping jaws typically begins with a single, complete circular part, which needs to be cut into multiple independent jaws of designed length. The traditional machining process involves the operator first fixing the ring in a vise, then manually aligning it using a right-angle ruler to ensure the accuracy of the initial cutting line. After cutting one jaw, the clamp must be released, the part manually rotated to a predetermined angle, and this tedious alignment and clamping process must be repeated before the next cut can begin. This cyclical work pattern, heavily reliant on manual judgment and adjustment, not only introduces operational instability and precision risks but also severely encroaches on effective cutting time due to the repetitive and time-consuming clamping and alignment steps, ultimately resulting in extremely low overall cutting efficiency.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0022] This application provides a clamping jaw cutting fixture and its usage method, which can solve the problem of low cutting efficiency caused by repeated manual alignment and clamping when cutting workpieces to form clamping jaws in the prior art.

[0023] See Figures 1 to 3 , Figure 8 As shown, in a first aspect, embodiments of this application provide a clamping jaw cutting fixture, comprising: The support frame 6 includes a base 61 and two support sections 62 spaced apart along the length of the base 61, with a device placement area formed between the two sides of the support sections 62. Two clamping discs 1 are arranged opposite to each other in the device placement area, and a clamping space for axially limiting multiple workpieces 2 is formed between the two clamping discs 1. Multiple positioning grooves 12 are arranged circumferentially on the clamping discs 1 for positioning the cutting tool when cutting the workpiece 2. The rotating shaft 3 is rotatably connected to the limiting groove 621 of the support section 62, and the rotating shaft 3 is connected through the two clamping disks 1 and protrudes from both sides of the two clamping disks 1 respectively; the rotating shaft 3 is detachably connected to the abutment 9 of the axial limiting clamping disk 1.

[0024] In practical use, the support frame 6 consists of a base 61 and two support sections 62 spaced apart along the length of the base 61, forming a device placement area between the two sides of the support sections 62. This structure provides a stable support foundation for the entire fixture, ensuring that the fixture as a whole will not shake or shift due to external forces during the cutting process, thereby guaranteeing the stability of the cutting process and improving cutting accuracy.

[0025] Two opposing clamping discs 1 are positioned in the device placement area, forming a clamping space between them to axially limit multiple workpieces 2. This allows for simultaneous axial restraint of multiple workpieces 2, enabling clamping of multiple workpieces 2 at once and reducing the number of clamping operations. Simultaneously, multiple circumferentially spaced positioning grooves 12 on the clamping discs 1 effectively position and avoid the cutting tool during workpiece cutting, preventing interference between the tool and the clamping discs 1. Furthermore, the positioning grooves 12 also position the tool, guiding it to the cutting position. Specifically, after cutting the workpiece 2 using the cutting tool through one positioning groove 12, the entire device is rotated, and the cutting tool is then used to cut the workpiece 2 through another positioning groove 12, thus completing the cutting of one clamping jaw (because in practice, such as...). Figure 9 The workpiece 2 is a ring shape and can be cut into multiple clamping claws. Each clamping claw can be regarded as a segment of arc-shaped structure cut off from the ring workpiece 2. The distance between the two positioning slots 12 can be set according to the length of the clamping claw to facilitate cutting, thereby ensuring the smooth progress of the cutting operation and improving the feasibility of the cutting operation.

[0026] like Figure 2 and Figure 5 The rotating shaft 3 is rotatably connected to the limiting groove 621 of the support section 62, and passes through and connects to the two clamping discs 1, protruding from both sides of the two clamping discs 1 respectively. An axially limiting clamping disc 1 abutment 9 is detachably connected to the rotating shaft 3. Through the setting of the rotating shaft 3, the two clamping discs 1 can rotate around the rotating shaft 3. After cutting one clamping claw on the workpiece 2, there is no need to release the clamps or manually rotate the parts. Simply rotate the rotating shaft 3 to rotate the clamping disc 1 and the workpiece 2 to a predetermined angle, and the next cut can be performed, thereby cutting the workpiece 2 into multiple clamping claws, simplifying the operation process. The detachably connected abutment 9 can axially limit the clamping disc 1, preventing axial movement of the clamping disc 1 during the cutting process, ensuring the accuracy of the cutting position, effectively solving the problem of low cutting efficiency caused by repeated manual alignment and clamping in the prior art, and improving the overall cutting efficiency.

[0027] In some alternative embodiments, such as Figure 4 and Figure 7 As shown, a rotating component 4 is provided on one side of the rotating shaft 3 to drive the rotating shaft 3 to rotate, and a locking assembly with a limit rotating component 4 is provided on the support section 62.

[0028] By installing a rotating component 4 on one side of the rotating shaft 3, a convenient operation method is provided for the rotation of the rotating shaft 3. The operator only needs to apply force to the rotating component 4 to easily rotate the rotating shaft 3, thereby rotating the clamping plate 1 and the workpiece 2. No direct operation of the rotating shaft 3 is required, making operation more convenient and labor-saving, and improving operational convenience and efficiency. A locking assembly is installed on the support section 62 to limit the rotation of the rotating component 4. This effectively fixes the rotating component 4 after the workpiece 2 has rotated to a predetermined angle, preventing it from continuing to rotate. This ensures that the position of the workpiece 2 remains stable during the cutting process, preventing angular displacement due to accidental rotation of the rotating component 4, thus ensuring the accuracy of the cutting position, improving cutting precision, and guaranteeing the processing quality of the clamping jaws.

[0029] In practice, the device can be used on a saw. When the saw is cutting (the cutting tool is a saw blade), the stable structure of the fixture can prevent the clamping plate 1 from shaking, thereby ensuring that the workpiece 2 is fixed in position, so that the saw blade can cut along the positioning groove 12 of the clamping plate 1 according to the predetermined trajectory, reducing cutting deviation and improving cutting dimensional accuracy.

[0030] In some alternative embodiments, such as Figure 7 As shown, the locking assembly includes a mounting plate 7 fixed to the side wall of the support section 62 and an axial abutment member 8 connected to the mounting plate 7. The axial abutment member 8 is used to move axially along the mounting plate 7 to abut against the limiting rotation member 4.

[0031] The mounting plate 7 is fixed to the side wall of the support section 62, providing a stable mounting base for the axial abutment member 8. This ensures that the axial abutment member 8 can be reliably connected to the support section 62, guaranteeing the structural stability of the entire locking assembly and providing assurance for subsequent limiting operations on the rotating member 4. The axial abutment member 8 can move axially along the mounting plate 7. This design allows the operator to flexibly adjust the position of the axial abutment member 8 according to actual needs. When it is necessary to limit the rotating member 4, the axial abutment member 8 is moved to the position of abutting the rotating member 4 to fix the rotating member 4; when it is necessary to rotate the rotating member 4, the axial abutment member 8 is removed to release the limiting operation on the rotating member 4. The operation is flexible and convenient, and can meet the needs of adjusting and fixing different cutting angles.

[0032] In some alternative embodiments, such as Figure 4 and Figure 7 As shown, the rotating part 4 has a hollow structure and is fixed to the outer wall of the rotating shaft 3. The rotating part 4 includes a connecting part 41 connected to the rotating shaft 3 and a plurality of bosses 42 spaced circumferentially along the outer wall of the connecting part 41. The axial abutting member 8 includes an abutting joint 81 that abuts against the rotating member 4 and a connecting rod 82 that passes through and is connected to the mounting plate 7; a return spring 83 is sleeved on the outer wall of the connecting rod 82, one end of the return spring 83 abuts against the abutting joint 81 and the other end abuts against the mounting plate 7.

[0033] The rotating member 4 is in a hollow structure and is fixed to the outer wall of the rotating shaft 3. This structure makes the connection between the rotating member 4 and the rotating shaft 3 more compact and stable, and can better transmit the rotating torque, ensuring that the rotating member 4 does not slip when driving the rotating shaft 3 to rotate, thereby improving the reliability and stability of rotation.

[0034] The plurality of bosses 42 arranged circumferentially along the outer wall of the connecting portion 41 provides more operating force points for the operator. The operator can drive the rotating member 4 to rotate by pushing different bosses 42, making the operation more convenient and labor-saving, and also facilitating more accurate control of the rotation angle of the rotating member 4 according to different cutting angle requirements.

[0035] The abutting head 81 is used to abut the rotating member 4, and the connecting rod 82 is connected to the mounting plate 7. This structure enables the axial abutting member 8 to be stably mounted on the mounting plate 7 and accurately abut the rotating member 4, thereby achieving the limiting effect on the rotating member 4. The reset spring 83 is sleeved on the outer wall of the connecting rod 82. When the axial abutting member 8 abuts the rotating member 4, the reset spring 83 is compressed and generates a spring force. When it is necessary to release the limiting of the rotating member 4, the connecting rod 82 is pulled towards the mounting plate 7, and the abutting of the rotating member 4 is released. After the rotating member 4 is rotated again, the connecting rod 82 is released, and the spring force of the reset spring 83 automatically resets the axial abutting member 8 to the initial position, facilitating the limiting operation next time. This automatic reset function improves the convenience and efficiency of operation, and reduces the time and effort of manual adjustment.

[0036] In practice, the boss 42 is in a trapezoidal structure, and the end face of the abutting head 81 is in a wedge shape, which is used to match the abutting space between the adjacent two bosses 42. This can improve the abutting stability of the rotating member 4 and ensure the cutting accuracy and efficiency.

[0037] As shown in Figure 7 , a sleeve 84 is sleeved on the end of the connecting rod 82, the diameter of the sleeve 84 is larger than that of the connecting rod 82, a hole is arranged on the sleeve 84, and a connecting hole matched with the hole is arranged on the connecting rod 82. The sleeve 84 and the connecting rod 82 are fixed by a latch to prevent the connecting rod 82 from moving towards the rotating member 4 during the use of the tool, thereby avoiding affecting the cutting.

[0038] In some optional embodiments, as shown in Figure 6 and Figure 8 , the rotating shaft 3 includes a column body 31 and a rectangular protruding portion 32 protruding from the side wall of the column body 31, and the center part of the clamping disc 1 is provided with a connecting groove 13 matched with the column body 31 and the rectangular protruding portion 32.

[0039] The cylinder 31 of the rotating shaft 3 matches the cylindrical part of the connecting groove 13 of the clamping disc 1, which can realize preliminary radial positioning and ensure that the clamping disc 1 can be accurately aligned with the rotating shaft 3 during installation. The rectangular protruding part 32 matches the corresponding rectangular part in the connecting groove 13, which further limits the circumferential rotation of the clamping disc 1 relative to the rotating shaft 3, so that a stable connection is formed between the clamping disc 1 and the rotating shaft 3. This design ensures that the clamping disc 1 will not rotate or deviate relative to the rotating shaft 3 during cutting due to external forces, thereby improving the stability of the entire tooling and facilitating the guarantee of cutting accuracy.

[0040] This structure is convenient for installing and dismounting the clamping disc 1. The operator only needs to align the connecting groove 13 of the clamping disc 1 with the cylinder 31 and the rectangular protruding part 32 of the rotating shaft 3, and gently sleeve it to complete the installation; when dismounting, only a certain external force is needed to pull the clamping disc 1 out of the rotating shaft 3. This convenient installation and dismounting method improves the assembly and maintenance efficiency of the tooling.

[0041] In some optional embodiments, as shown in Figure 6 , Figure 8 and Figure 9 , the workpiece 2 has a hollow annular structure, the clamping disc 1 is circular, the diameter of the clamping disc 1 is greater than the diameter of the workpiece 2, and the outer periphery of the side wall of the clamping disc 1 is provided with a resisting part 11 for limiting the workpiece 2 in the radial direction.

[0042] Since the diameter of the clamping disc 1 is greater than the diameter of the workpiece 2, and the outer periphery of the side wall is provided with the resisting part 11, when the workpiece 2 is placed between the two clamping discs 1, the resisting part 11 can limit the workpiece 2 in the radial direction, preventing the workpiece 2 from moving radially during cutting. This radial limiting method can ensure that the workpiece 2 always remains in the correct position during cutting, ensuring the accuracy of the cutting position and thus ensuring the cutting quality of the clamping jaw.

[0043] In some optional embodiments, as shown in Figure 8 and Figure 9 , the workpiece 2 has a hollow annular structure, and the depth of the positioning groove 12 is greater than the ring width of the workpiece 2. The depth of the positioning groove 12 is greater than the ring width of the workpiece 2, so that during cutting, the cutting tool can directly cut the ring piece of the workpiece 2 through the positioning groove 12, avoiding interference with the cutting work.

[0044] In some optional embodiments, as shown in Figures 2 to 4 , a bushing 33 is arranged on the outer wall of the rotating shaft 3 away from the rotating part 4; A resisting part 5 for resisting the bushing 33 is arranged on the support section 62 away from the rotating part 4; the resisting part 5 is a butterfly bolt which is rotationally connected to the support section 62.

[0045] The bushing 33 is arranged on the outer wall of the rotating shaft 3 away from the rotating part 4, and the abutting part 5 (butterfly bolt) is rotationally connected to the supporting section 62 and abuts against the bushing 33, which can limit the axial position of the rotating shaft 3. During the cutting process, the axial movement of the rotating shaft 3 due to the axial force is prevented, the stability of the rotating shaft 3 is ensured, and the position stability of the clamping disc 1 and the workpiece 2 is ensured, which is beneficial to improve the cutting precision.

[0046] The butterfly bolt is used as the abutting part 5, and the operator does not need to use tools, but only needs to manually rotate the butterfly bolt to abut against and loosen the bushing 33. This convenient operation mode makes it more convenient and fast to adjust the axial position of the rotating shaft 3 or to perform the assembly and disassembly operation, and improves the work efficiency.

[0047] In some optional embodiments, as Figure 1 and Figure 6 The abutting part 9 is a locking nut, which is rotationally connected to the rotating shaft 3.

[0048] The locking nut is rotationally connected to the rotating shaft 3, and by tightening the locking nut, the locking nut can be tightly fixed on the rotating shaft 3, thereby reliably fixing the clamping disc 1 and other components in the axial direction. During the cutting process, the axial movement of the clamping disc 1 due to the axial force is effectively prevented, the overall structural stability of the tooling is ensured, and the cutting precision is ensured.

[0049] In practice, the locking nut can be arranged on the end of the clamping disc 1 on one side of the rotating shaft 3 (the other clamping disc 1 can be provided with a fixing part similar to the bushing for axial fixation), so that the operator does not need to operate at two positions, and the operation is more concentrated and convenient. The locking nut can also be arranged on both sides of the two clamping discs 1, and the axial fixing force can be applied to both sides of the workpiece 2 at the same time, so that the force received by the workpiece 2 in the axial direction is more uniform.

[0050] In a second aspect, the embodiments of the present application also provide a use method of the clamping jaw cutting tooling, which is implemented by using any one of the above clamping jaw cutting tooling, and the method comprises the following steps: The rotating shaft 3 is inserted through the two clamping discs 1 and the plurality of workpieces 2 to be cut, and the plurality of workpieces 2 to be cut are clamped by the two clamping discs 1; The abutting part 9 is used to limit and fix the clamping disc 1; The cutting tool is aligned with the positioning groove 12 on the clamping disc 1 to simultaneously cut the plurality of workpieces 2 to be cut; The rotating shaft 3 is rotated, and the cutting tool is repeatedly used to cut the plurality of workpieces 2 to be cut until the workpieces 2 are cut.

[0051] In practice, the device can be used on a saw. When the saw is cutting (the cutting tool is a saw blade), the stable structure of the fixture can prevent the clamping disc 1 from shaking, thereby ensuring that the workpiece 2 is fixed in position, so that the saw blade can cut along the positioning groove 12 of the clamping disc 1 according to the predetermined trajectory, reducing cutting deviation and improving cutting dimensional accuracy.

[0052] The clamping jaw cutting fixture method provided in this application embodiment, in actual operation, firstly, the rotating shaft 3 passes through two clamping discs 1 and multiple workpieces 2 to be cut. The two clamping discs 1 clamp the multiple workpieces 2, and then the abutment 9 is used to limit and fix the clamping discs 1. This design ensures the initial stable positioning of the workpieces 2 before cutting. In practice, when the device is placed on a sawing machine and the saw blade is used as the cutting tool, the stable structure of the fixture can effectively prevent the clamping discs 1 from shaking, ensuring the fixed position of the workpieces 2. This allows the saw blade to accurately cut along the positioning grooves 12 on the clamping discs 1 according to a predetermined trajectory, greatly reducing cutting deviation and significantly improving cutting dimensional accuracy. Moreover, this method can use the cutting tool to cut multiple workpieces 2 simultaneously, and after one cut, the rotating shaft 3 is rotated to allow the cutting tool to repeat the cut until the workpieces 2 are cut. This batch cutting and repeated cutting method greatly improves cutting efficiency while ensuring cutting quality and reduces the cutting cost of a single workpiece 2, making it suitable for large-scale workpiece 2 cutting production scenarios.
