Description

Technical Field

[0001] The present invention relates to the technical field of parts processing and positioning, and in particular to a positioning device for parts processing and a use method thereof. Background Art

[0002] In industrial products, shaft parts are suitable for maintenance operations of one or more CNC machine tool processing parts. Shaft parts are one of the typical parts often encountered in hardware accessories. They are mainly used to support transmission components, transmit torque and bear loads. According to the different structural forms of shaft parts, they can generally be divided into smooth shafts, stepped shafts, special-shaped shafts, solid shafts, hollow shafts, etc.

[0003] The patent with authorization announcement number CN118003127B discloses a center hole positioning structure for shaft parts, including a workbench, the workbench includes a frame and a base plate, and the base plate is fixedly installed on the bottom end of the frame, the clamping mechanism is fixedly installed on the outside of the frame, the clamping mechanism includes a first hollow disc, and the first hollow disc is fixedly installed on the outside of the frame, and a motor is fixedly installed at the bottom end of the first hollow disc.

[0004] However, the above-mentioned center hole positioning structure for shaft parts still has some shortcomings in actual use: 1. By setting the first round block and the second round block, when the motor drives the clamping assembly to clamp the shaft part through the connecting assembly, the first round block and the second round block rotate, so that when the first round block and the second round block collide with the outer side of the shaft part, there is a stable downward force on the shaft part, which is conducive to the flat bottom of the shaft part to collide with the top of the frame, thereby improving the verticality between the shaft part and the frame, making the center hole positioning of the shaft part more accurate. The basis for the above-mentioned implementation is that the end of the shaft part is a plane. If 1. If the processed shaft end becomes a special shape or a curved surface, it cannot be used; 2. The above-mentioned center hole positioning structure of shaft parts sets up a series of transmission structures, which only realizes that when the first round block and the second round block conflict with the outer side of the shaft parts, there is a stable downward force on the shaft parts and it is convenient to remove the shaft parts from directly above the frame. If it is necessary to process the end, inner wall and outer wall of the shaft parts, after one end is processed, the end end is no longer a plane. This device cannot locate the center of the shaft parts. Therefore, a positioning device and a method for using parts processing are proposed to solve the above-mentioned problems.

[0015] Compared with the prior art, the advantages of the positioning device and the use method for parts processing provided by the present invention are: 1. The moving motor continues to rotate, driving the second mounting seat to approach the first mounting seat. When the conforming column collides with the end of the special-shaped shaft part, the twenty-five conforming columns will be in close contact with the end of the special-shaped shaft part; 2. When any one of the follow-up columns is retracted into the second limit slide rail to the maximum extent, the triangular block will contact the trigger frame, causing the trigger frame to move a section, thereby driving the locking gear to rotate 90 degrees through the intermittent rack frame, so that the locking cam rotates to push the mounting plate toward the follow-up column, so that the locking plate clamps the outer wall of the follow-up column, so that it locks the position of each follow-up column at this time, preventing the elastic force of the fourth reset spring from acting on the shaft parts; 3. When the sliding rod 2 drives the fixing frame to move to the maximum limit, the gear 3 meshes with the second rack, and the gear 3 drives the rotating cylinder to rotate so that the rotating cylinder is wound around the traction rope, so that the traction rope pulls the clamping rubber downward and inward, thereby strengthening the clamping rubber to the outer wall of the special-shaped shaft parts, giving it a force toward the second mounting seat; To summarize, the present invention performs preliminary axial center positioning on shaft parts through the initial clamping mechanism, and then when one end of the shaft part is irregularly shaped after processing, the conforming mechanism is used to stick to the irregular end face, and then any conforming mechanism can trigger the axial center holding mechanism to lock the position of each conforming column at this time. The conforming mechanism is suitable for irregular surfaces of any shape, and the conforming mechanism can cooperate with the clamping locking pressurizing mechanism to make the non-planar clamping mechanism pull downward and inward, thereby enhancing the clamping of the clamping rubber to the outer wall of the irregular shaft part.

[0025] In this embodiment, if Figure 5 As shown: when the end of the shaft part is flush with the end of the follower column 28, the moving motor 7 stops rotating, and the clamping motor 2 33 rotates to drive the transmission gear 1 30 and the transmission gear column 32 to rotate, thereby driving the transmission gear ring 31 and the limiting slide rail 1 291 to rotate, and the mounting rod 23 slides along the limiting slide rail 1 291 to the protrusion of the limiting slide rail 1 291, so that the clamping rubber 38 clamps the outer wall of the shaft part.

When the conforming column 28 collides with the end of the special-shaped shaft part, the twenty-five conforming columns 28 will be tightly attached to the end of the special-shaped shaft part.

[0030] like Fig.13 As shown: no matter what the shape of the end of the special-shaped shaft part is, it is set that as long as any of the shaped columns 28 is retracted into the second limiting slide rail 29 to the maximum extent, the triangular block 52 will resist the trigger frame 44, that is, the shaped column 28 moves with the triangular block 52 along the slide groove on the second limiting slide rail 29 until the inclined surface of the triangular block 52 pushes the trigger frame 44, so that the trigger frame 44 moves along Fig.13 The locking gear 43 is driven to rotate ninety degrees through the intermittent rack 42 by sliding in the direction of the arrow.

[0031] Among them, the clamping, locking and pressurizing mechanism 303 includes a fixed frame 25, a rotating cylinder 26, a torsion spring 39, a gear three 40, a second rack 27 and a reset spring five 54.

[0033] like Fig. 9 and Fig.11 As shown, since the sliding rod 2 35 is slidably connected to the outer wall of the second mounting seat 3 , the clamping rubber 38 clamps the outer wall of the shaft part. Therefore, when the conformal column 28 gradually comes close to the end of the shaft part, the sliding rod 2 35 also moves towards the direction of the second mounting seat 3 .

[0034] like Fig.10 As shown: when the trigger frame 44 moves, it can extend into the block rod 41, thereby locking the position of the sliding rod 35 and preventing the sliding rod 35 from moving upward.

[0035] like Fig. 9 As shown in FIG. 1 , the second rack 27 is always in close contact with one side of the fixing frame 25 due to the action of the return spring 54. When the sliding rod 35 drives the fixing frame 25 to move down to the maximum limit, as shown in FIG. Fig.11 and Fig.12 As shown: gear three 40 is meshed with the second rack 27, gear three 40 drives the rotating cylinder 26 to rotate so that the rotating cylinder 26 is wrapped around the traction rope 34, so that the traction rope 34 pulls the clamping rubber 38 downward and inward, thereby enhancing the clamping of the clamping rubber 38 on the outer wall of the special-shaped shaft parts, giving it a force toward the second mounting seat 3, and a spring for providing reset is provided between the mounting seat 2 37 and the second clamping plate 22, thereby completing the clamping of the end of the special-shaped shaft.

[0036] The clamping motor 13 is reversed to release the clamping of the first clamping plate 9, so that the end and outer wall of the shaft part can be fully processed. After the processing is completed, the clamping motor 2 33 is reversed to reset.

[0037] A positioning method for part processing, which uses a positioning device for part processing, comprises the following steps: S1, the clamping motor 13 rotates to drive the clamping gear 14 to rotate, and the clamping gear 14 drives the three racks 11 to approach each other. When the first clamping plate 9 contacts the outer wall of the shaft part, the clamping side plate 15 also contacts the outer wall of the shaft part, thereby clamping the shaft part; S2. When only the outer wall and the end of the shaft part clamped by the first clamping plate 9 are left unprocessed, the two flip motors 4 rotate 90 degrees in the direction of the moving motor 7, and the moving motor 7 rotates so that the main gear 1 drives the displacement rack 6 to approach the first mounting seat 8 to perform the clamping exchange process; S3. When the end of the shaft part is flush with the end of the conforming column 28, the moving motor 7 stops rotating, the clamping motor 2 33 rotates to drive the transmission gear 1 30 and the transmission gear column 32 to rotate, thereby driving the transmission gear ring 31 and the limiting slide rail 1 291 to rotate, and the mounting rod 23 slides along the limiting slide rail 1 291 so that the clamping rubber 38 clamps the outer wall of the shaft part; S4, the moving motor 7 continues to rotate, driving the second mounting seat 3 to approach the first mounting seat 8, and when the conforming column 28 contacts the end of the special-shaped shaft part, the twenty-five conforming columns 28 will be in close contact with the end of the special-shaped shaft part; S5. When any one of the conforming columns 28 is retracted into the second limiting slide rail 29 to the maximum extent, the triangular block 52 will contact the trigger frame 44, causing the trigger frame 44 to move a certain distance, thereby driving the locking gear 43 to rotate 90 degrees through the intermittent rack frame 42, so that the locking cam 53 rotates to push the mounting plate 45 toward the conforming column 28, so that the locking plate 47 clamps the outer wall of the conforming column 28, so that it locks the position of each conforming column 28 at this time, and prevents the elastic force of the fourth reset spring 49 from acting on the shaft parts; S6, the second sliding rod 35 moves downward together with the follower column 28, and the trigger frame 44 is just stuck in the block rod 41 when moving, thereby locking the position of the second sliding rod 35; S7, when the sliding rod 25 drives the fixing frame 25 to move to the maximum limit, the gear 3 40 meshes with the second rack 27, and the gear 3 40 drives the rotating cylinder 26 to rotate so that the rotating cylinder 26 wraps around the traction rope 34, so that the traction rope 34 pulls the clamping rubber 38 downward and inward, thereby strengthening the clamping of the clamping rubber 38 on the outer wall of the special-shaped shaft part, giving it a force toward the second mounting seat 3; S8, the clamping motor 13 is reversed to contact the clamping of the first clamping plate 9, so that the end and outer wall of the shaft part can be fully processed. After the processing is completed, the clamping motor 2 33 is reversed to reset.

[0038] The specific working principle and method of use of the present invention are explained in detail below: Figure 1-4 As shown: first, the end of the shaft part is placed on the first mounting seat 8, and then the clamping motor 13 rotates to drive the clamping gear 14 to rotate, and the clamping gear 14 drives the three racks 11 to approach, and when the first clamping plate 9 contacts the outer wall of the shaft part, the clamping side plate 15 will also contact the outer wall of the shaft part, so as to better clamp the shaft part, and at the same time, the first gear 19 rotates along the first rack 18, so that the rubber ring 21 always rotates, so that when the rubber ring 21 contacts the outer wall of the shaft part, it can give it a force toward the first mounting seat 8, so that it is always close, ensuring the accuracy of the center line of the shaft part.

[0039] like Figure 1As shown: when only the outer wall and the end of the shaft part clamped by the first clamping plate 9 are left unprocessed, the two flip motors 4 rotate ninety degrees in the direction of the moving motor 7. The moving motor 7 rotates so that the main gear 1 drives the displacement rack 6 to approach the first mounting seat 8 to perform the clamping exchange process.

[0040] like Figure 5 As shown: when the end of the shaft part is flush with the end of the follower column 28, the moving motor 7 stops rotating, and the clamping motor 2 33 rotates to drive the transmission gear 1 30 and the transmission gear column 32 to rotate, thereby driving the transmission gear ring 31 and the limiting slide rail 1 291 to rotate, and the mounting rod 23 slides along the limiting slide rail 1 291 to the protrusion of the limiting slide rail 1 291, so that the clamping rubber 38 clamps the outer wall of the shaft part. At this time, the first clamping plate 9 always clamps the other end of the shaft part, so the center lines of the shaft parts are consistent at this time.

[0041] like Figure 1 As shown: the moving motor 7 then continues to rotate, driving the second mounting seat 3 to approach the first mounting seat 8. When the conforming column 28 collides with the end of the special-shaped shaft part, the twenty-five conforming columns 28 will be tightly attached to the end of the special-shaped shaft part.

[0042] like Fig.13 As shown: no matter what the shape of the end of the special-shaped shaft part is, it is set that as long as any of the shaped columns 28 is retracted into the second limiting slide rail 29 to the maximum extent, the triangular block 52 will resist the trigger frame 44, that is, the shaped column 28 moves with the triangular block 52 along the slide groove on the second limiting slide rail 29 until the inclined surface of the triangular block 52 pushes the trigger frame 44, so that the trigger frame 44 moves along Fig.13 The locking gear 43 is driven to rotate ninety degrees through the intermittent rack 42 by sliding in the direction of the arrow.

[0043] like Figure 8 As shown: the locking cam 53 rotates to push the mounting plate 45 toward the conformal column 28, so that the locking plate 47 clamps the outer wall of the conformal column 28, so that it locks the position of each conformal column 28 at this time, preventing the elastic force of the reset spring 49 from acting on the shaft parts.

[0044] like Fig. 9 and Fig.11 As shown, since the sliding rod 2 35 is slidably connected to the outer wall of the second mounting seat 3 , the clamping rubber 38 clamps the outer wall of the shaft part. Therefore, when the conformal column 28 gradually comes close to the end of the shaft part, the sliding rod 2 35 also moves towards the direction of the second mounting seat 3 .

[0045] like Fig.10 As shown: when the trigger frame 44 moves, it can extend into the block rod 41, thereby locking the position of the sliding rod 35 and preventing the sliding rod 35 from moving upward.

[0046] like Fig. 9 As shown in FIG. 1 , the second rack 27 is always in close contact with one side of the fixing frame 25 due to the action of the return spring 54. When the sliding rod 35 drives the fixing frame 25 to move down to the maximum limit, as shown in FIG. Fig.11 and Fig.12 As shown: gear three 40 is meshed with the second rack 27, gear three 40 drives the rotating cylinder 26 to rotate so that the rotating cylinder 26 is wrapped around the traction rope 34, so that the traction rope 34 pulls the clamping rubber 38 downward and inward, thereby enhancing the clamping of the clamping rubber 38 on the outer wall of the special-shaped shaft parts, giving it a force toward the second mounting seat 3, and a spring for providing reset is provided between the mounting seat 2 37 and the second clamping plate 22, thereby completing the clamping of the end of the special-shaped shaft.

[0047] The clamping motor 13 is reversed to release the clamping of the first clamping plate 9, so that the end and outer wall of the shaft part can be fully processed. After the processing is completed, the clamping motor 2 33 is reversed to reset.

[0048] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
