Description

Technical Field

[0001] This utility model relates to the technical field of workpiece processing equipment, and more specifically, to a burr removal device and workpiece processing equipment. Background Technology

[0002] During the machining process of mechanical parts, burrs are usually left on the cut surfaces. These burrs hinder further processing. This is especially true for complex mechanical parts. If burrs are present on the outer surface of the part, a vibratory grinding device can be used to remove them by vibrating and rubbing the parts against the grinding particles.

[0003] Some workpieces have multiple grooves on their circumference. The cleaning device needs to clean each groove one by one. Current deburring devices have difficulty locating the grooves, causing the grooves to be misaligned with the deburring structure, resulting in poor deburring effect. Utility Model Content

[0004] The purpose of this invention is to provide a burr removal device and workpiece processing equipment to solve the technical problem that the existing burr removal devices are prone to misalignment between the burr removal structure and the groove of the workpiece, resulting in poor burr removal effect.

[0021] By adopting the above technical solution, the correction part and the correction seat can be easily disassembled and assembled.

[0026] In one embodiment, the positioning element includes a positioning groove disposed on the circumferential direction of the drive wheel and corresponding one-to-one with the groove of the workpiece, and a positioning ball disposed on the drive seat for engaging the positioning groove.

[0027] By adopting the above technical solution, the distance of each rotation of the drive wheel in a positioning groove corresponds to the distance between two adjacent grooves on the workpiece, which is beneficial to the stepping rotation of the drive wheel.

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. The specific implementation of this utility model is described in more detail below with reference to specific embodiments:

[0046] like Figures 1 to 3 As shown in the figure, this utility model provides a burr removal device for removing burrs from the grooves 41 of a workpiece 4. In this embodiment, the workpiece 4 includes, but is not limited to, a knob with grooves 41, such as a watch crown. Multiple grooves 41 of the knob are arranged circumferentially around the knob, and the grooves 41 are used to increase friction when rotating the knob. The burr removal device provided in this embodiment has the ability to remove burrs from the grooves 41 of the workpiece 4, and at the same time, it has high burr removal efficiency, thus improving the production efficiency of the workpiece 4. The following is a detailed description of the specific implementation:

[0047] The burr removal device in this embodiment includes:

[0048] Base 1, correction mechanism 2 and drive mechanism 3 mounted on base 1;

[0049] like Figure 4 As shown, the correction mechanism 2 includes a correction seat 21 disposed on the base 1 and a correction component 22 detachably connected to the correction seat 21. The correction seat 21 is used to limit the workpiece 4, and the correction component 22 is provided with a correction structure 221 for inserting the groove 41 of the workpiece 4.

[0050] The drive mechanism 3 includes a drive seat 31 mounted on the base 1, a drive wheel 32 connected to the drive seat 31, and a drive shaft 33 connected to the drive wheel 32; the drive seat 31 and the correction seat 21 are spaced apart, the drive wheel 32 can drive the drive shaft 33 to rotate around the axis, and the drive shaft 33 is provided with a drive end 331 that is connected to the correction seat 21 and fixedly connected to the workpiece 4.

[0051] When the drive wheel 32 drives the drive shaft 33 to rotate, the drive end 331 drives the workpiece 4 to rotate to the correction position. The correction structure 221 can be placed into the groove 41 located at the correction position to correct the position of the groove 41.

[0052] Here, it can be understood that base 1 refers to the seat used to support correction mechanism 2 and drive mechanism 3;

[0053] The correction mechanism 2 refers to a mechanism for removing burrs. The correction mechanism 2 includes a correction seat 21 and a correction element 22. The correction seat 21 is disposed on the base 1 and is used to limit the workpiece 4. In this embodiment, the workpiece 4 is described as a knob with a groove 41. The correction seat 21 restricts the movement of the workpiece 4, so that the workpiece 4 can only rotate around the axis on the correction seat 21. The correction element 22 is detachably connected to the correction seat 21. The correction element 22 is provided with a correction structure 221, which is used to be inserted into the groove 41 of the workpiece 4. The shape and size of the correction structure 221 match the shape and size of the groove 41 of the workpiece 4, so that the correction structure 221 can be inserted into the groove 41. When there is a slight misalignment between the correction structure 221 and the groove 41, the insertion of the correction structure 221 can squeeze the groove wall of the groove 41, so that the groove 41 corrects its own position, which is convenient for subsequent alignment with the burr cleaning structure.

[0054] Drive mechanism 3 refers to the mechanism used to drive correction mechanism 2; drive mechanism 3 includes drive base 31, drive wheel 32, and drive shaft 33; drive base 31 is mounted on base 1, and drive base 31 supports drive wheel 32 and drive shaft 33, drive base 31 is spaced apart from correction base 21; drive wheel 32 is a component used to drive drive shaft 33 to rotate around its axis, drive wheel 32 can be driven manually or electrically; drive shaft 33 is a shaft that transmits the rotation of drive wheel 32, drive shaft 33 connects drive wheel 2 and correction base 21, and drives... The moving shaft 33 is provided with a driving end 331, which is used to fix the workpiece 4. In this way, the driving end 331 can drive the workpiece 4 to rotate around the shaft. The workpiece 4 has multiple grooves 41 arranged in the circumferential direction. The grooves 41 need to be rotated one by one to the correction position and aligned with the burr removal structure to remove burrs. When the groove 41 is rotated to the correction position, the correction seat 21 is connected to the driving seat 31, so that the correction structure 221 is placed in the groove 41. In this way, the position of the correction groove 41 is corrected so that the groove 41 is in the correct position.

[0055] The working principle of the burr removal device provided in this embodiment is as follows:

[0056] Remove the corrector 22 from the corrector base 21. Drive the drive wheel 32 manually or electrically to rotate the drive shaft 33, thereby causing the drive end 331 and the workpiece 4 fixed to the drive end 331 to rotate around the axis. The groove 41 of the workpiece 4 rotates with the workpiece 4. The multiple grooves 41 on the workpiece 4 rotate one by one to the corrected position. Here, the corrected position refers to the position that can be roughly aligned with the burr removal structure. When the groove 41 rotates to the corrected position, the groove 41 is not yet fully aligned with the burr removal structure. Then fix the corrector 22 to the corrector base 21. At this time, install the corrector 22 on the corrector base 21. The corrected protrusion on the corrector 22 can be placed into the groove 41. By pressing the groove wall of the groove 41 with the corrected protrusion, the workpiece 4 is driven to rotate slightly around the axis, so that the groove 41 is corrected to the appropriate position and finally aligned with the burr removal structure.

[0057] By adopting the above technical solution:

[0058] The drive mechanism 3 can drive the groove 41 on the workpiece 4 to rotate to the correction position, so that the groove 41 is roughly aligned with the subsequent burr removal structure, that is, the groove 41 is initially corrected; the correction mechanism 2 can further adjust the groove 41 in the correction position to a suitable position, that is, the groove 41 is corrected in the second step. In this way, the groove 41 can be aligned with the subsequent burr removal structure, reducing the possibility of misalignment between the groove 41 and the burr removal structure, which is conducive to the operation of the burr removal structure and improves the burr removal effect.

[0059] In one embodiment, the correction mechanism 2 includes a limiting part 23 detachably mounted on the correction seat 21, the limiting part 23 being used to limit the workpiece 4.

[0060] Here, it can be understood that the limiting part 23 refers to the component used to limit the workpiece 4; in this embodiment, the limiting part 23 and the correction seat 21 are detachably installed, that is, the limiting part 23 can be removed from the correction seat 21, so that the workpiece 4 can be installed and removed when the limiting part 23 is removed.

[0061] By adopting the above technical solution, it is beneficial to install and disassemble workpiece 4.

[0062] In one embodiment, the limiting part 23 is provided with a limiting groove 231, a driving hole 232 communicating with the limiting groove 231 and a correction hole 233. The limiting groove 231 is used to limit the workpiece 4, the driving hole 232 is used to receive the driving end 331 of the driving shaft 33, and the correction hole 233 is used to accommodate the correction structure 221. The correction hole 233 corresponds to the correction position.

[0063] Here, it can be understood that the shape and size of the limiting groove 231 match the shape and size of the workpiece 4, so that the workpiece 4 can be just accommodated in the limiting groove 231 and limited; the shape and size of the driving hole 232 match the shape and size of the driving shaft 33, so that the driving end 331 can be just inserted into the driving hole 232 and fixedly connected to the workpiece 4; the shape and size of the correction hole 233 match the shape and size of the groove 41 of the workpiece 4, so that the correction hole 233 can just expose the groove 41, which is conducive to the deburring structure to perform its work.

[0064] The working principle of the burr removal device provided in this embodiment is as follows:

[0065] The groove 41 of the workpiece 4 rotates around the axis under the drive end 331 and stops at the correction position. At this time, the correction hole 233 exposes the groove 41. The shape and size of the correction structure 221 match the shape and size of the correction hole 233, so that the correction structure 221 can just pass through the correction hole 233 and be placed in the groove 41.

[0066] By adopting the above technical solution, the modified hole 233 can just expose the groove 41, so that the burr removal structure can work on the groove 41, which helps to improve the burr removal effect.

[0067] like Figure 4 and Figure 5 As shown, in one embodiment, the drive end 331 includes a first clamping part 3311 disposed on the drive shaft 33 and a second clamping part 3312 disposed at a distance from the first clamping part 3311. The second clamping part 3312 is detachably connected to the drive shaft 33. The first clamping part 3311 and the second clamping part 3312 are used to jointly fix the workpiece 4.

[0068] Here, it can be understood that the first clamping part 3311 and the second clamping part 3312 are spaced apart, and the distance between them matches the size of the workpiece 4, so that the workpiece 4 can be clamped just between the first clamping part 3311 and the second clamping part 3312.

[0069] By adopting the above technical solution, it is beneficial to fix the drive end 331 to the workpiece 4.

[0070] In one embodiment, the second clamping part 3312 is threadedly connected to the drive shaft 33.

[0071] Here, it can be understood that the second clamping part 3312 is a nut in this embodiment.

[0072] By adopting the above technical solution, it is beneficial to disassemble and assemble the second clamping part 3312, making it convenient to disassemble and assemble the workpiece 4 and the driving end 331.

[0073] Please also refer to Figure 3 and Figure 6 In one embodiment, the correction base 21 is provided with a connection hole 211, and the correction component 22 is provided with a connector 222 that is inserted into the connection hole 211 to allow the correction component 22 to be detachably connected to the correction base 21.

[0074] Here, it can be understood that the shape and size of the connecting hole 211 match the shape and size of the connector 222, so that the connector 222 can be interference-fitted with the connecting hole 211, and the correction part 22 is fixedly connected to the correction seat 21 by the force of the interference fit.

[0075] By adopting the above technical solution, the correction component 22 and the correction base 21 can be easily disassembled and assembled.

[0076] In one embodiment, the correction base 21 is provided with an electromagnetic element 212, and the correction element 22 is provided with a magnetic element 223 that magnetically cooperates with the electromagnetic element 212 to detachably connect the correction element 22 to the correction base 21; the electromagnetic element 212 can adjust its own magnetism to attract or repel the magnetic element 223.

[0077] Here, it can be understood that the electromagnetic component 212 refers to adjusting the direction of the magnetic field by adjusting the direction of the current, thereby achieving the function of magnetic attraction or repulsion with the magnetic component 223. In this embodiment, the workpiece 4 can be the crown of a watch. Since the workpiece 4 is small in size, it is easy to cause the correction seat 21 to shake and cause the workpiece 4 to shift when the correction component 22 is disassembled. At this time, by adjusting the direction of the magnetic field of the electromagnetic component 212, the electromagnetic component 212 and the magnetic component 223 repel each other. In this way, the correction component 22 separates from the correction seat 21 through the mutual repulsion force, thereby reducing the possibility of displacement of the correction seat 21 and the workpiece 4 fixed on the correction seat 21, and avoiding affecting the accuracy of the subsequent burr removal operation.

[0078] It needs to be further explained that the corrector 22 is equipped with a switch that is electrically connected to the electromagnetic component 212. When the operator manually disassembles and repairs the corrector 22, he / she can directly operate the magnetism of the electromagnetic component 212 through the switch. This makes the control and operation of the electromagnetic component 212 highly convenient.

[0079] By adopting the above technical solution, the possibility of workpiece 4 shifting due to disassembly of the correction part 22 is reduced, and the accuracy of deburring operation is improved.

[0080] Please refer to this page. Figure 4 In one embodiment, the drive mechanism 3 further includes a positioning member 34 for positioning the drive wheel 32, the positioning member 34 being used to abut against the drive wheel 32 to keep the drive wheel 32 in a set position.

[0081] Here, it can be understood that the set position corresponds to the corrected position, that is, when the drive wheel 32 is positioned at the set position, the workpiece 4 is just at the corrected position.

[0082] By adopting the above technical solution, it is easier for the operator to control the drive wheel 32 to rotate to the set position, and it is easier to align the workpiece 4 with the correction position.

[0083] In one embodiment, the positioning member 34 includes a positioning groove 341 located on the circumferential direction of the drive wheel 32 and corresponding one-to-one with the groove 41 of the workpiece 4, and a positioning ball 342 located on the drive seat 31 for engaging the positioning groove 341.

[0084] Here, it can be understood that the shape and size of the positioning ball 342 and the positioning groove 341 are matched so that the positioning ball 342 can be just inserted into the positioning groove 341, so that the groove 41 of the workpiece 4 is just in the correction position.

[0085] It needs to be further explained that, since the positioning groove 341 corresponds one-to-one with the groove 41 of the workpiece 4, that is, the positioning groove 341 and the groove 41 rotate synchronously, after the first groove 41 of the workpiece 4 is corrected, the user can rotate the position of one positioning groove 341 of the drive wheel 32 to synchronously rotate the next groove 41 of the workpiece 4 to the correction hole 233 for deburring. In this way, multiple grooves 41 on the workpiece 4 can be deburred one by one. At the same time, a mark can be made on the drive wheel 32 to indicate that the drive wheel 32 has rotated one revolution, avoiding repeated deburring of the same groove 41.

[0086] In addition, the positioning ball 342 is connected to the drive seat 31 by a pressure plate 343. The pressure plate 343 has tension and is used to keep the positioning ball 342 pressing against the positioning groove 341, so that the drive wheel 32 rotates step by step.

[0087] By adopting the above technical solution, the distance of each rotation of the drive wheel 32 in a positioning groove 341 corresponds to the distance between two adjacent grooves 41 of the workpiece 4, which is beneficial to the stepping rotation of the drive wheel 32.

[0088] Secondly, a workpiece processing device is provided, including a workpiece processing device body and the aforementioned burr removal device, wherein the burr removal device is disposed on the workpiece processing device body.

[0089] By adopting the above technical solution, the workpiece processing equipment of this embodiment has the advantage of high processing efficiency, in addition to the advantages of the burr removal device of the above embodiment.

[0090] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
