Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy processing technology, and in particular to a surface grinding fixture for aluminum alloy parts. Background Technology

[0002] The machining process for aluminum alloy parts can be divided into roughing and finishing. After roughing, the parts undergo heat treatment to fully release the cutting stress and residual stress before finishing. This greatly improves the quality of the parts. Fine machining processes for aluminum alloys include stamping, CNC machining, polishing, sandblasting, wire drawing, oxidation, baking paint, screen printing, pad printing, laser engraving, high gloss, and deburring. However, during the production of aluminum alloy workpieces, residual chips and extremely fine microscopic metal particles appear on the surface, which are called burrs. The presence of burrs greatly affects the appearance and installation accuracy of the workpiece. Therefore, deburring is an important step in the workpiece machining process. Currently, after aluminum alloy parts are formed, their edges need to be deburred. However, much of the deburring work is currently done manually by workers, which is too inefficient and cannot meet current usage requirements.

[0003] Existing patent number CN221390237U discloses a deburring device for aluminum alloy workpieces, including a base with a through hole in the middle of the top surface of the base, and further including: a clamping assembly disposed in the middle of the top surface of the base, used to clamp and position the aluminum alloy workpiece to be deburred; and a grinding assembly disposed directly above the clamping assembly, with one end of the grinding assembly connected to the top surface of the base, used to grind the burrs on the aluminum alloy workpiece held by the clamping assembly. This invention can improve the efficiency of deburring aluminum alloy workpieces, reduce the labor intensity and cost of workers, and also clean up the debris during the deburring process, reducing the harm of debris to workers.

[0004] Using the above method, it was found that after machining one surface of the workpiece, when machining other surfaces is required, the clamping assembly needs to be disassembled and the workpiece flipped over. Only after reinstalling the clamping assembly can machining continue, which wastes both time and manpower. Utility Model Content

[0005] The purpose of this utility model is to provide a surface grinding fixture for aluminum alloy parts, which solves the problem found in the use of existing devices that, after processing one surface of the workpiece, when processing other surfaces is required, the clamping assembly needs to be disassembled and the workpiece flipped over, and the clamping assembly needs to be reinstalled before processing can continue, thus wasting both time and manpower.

[0006] To achieve the above objectives, this utility model provides a surface grinding fixture for aluminum alloy parts, including an operating table, a grinding assembly, a support ring, an electric push rod, and a resisting plate. The grinding assembly is disposed on the operating table, the support ring is fixedly installed on the operating table, the electric push rod is installed on the support ring, and the resisting plate is installed on the electric push rod.

[0007] The system also includes a rotating mechanism, which comprises a rotating disk, a fixed plate, a rotating disc, a fixed seat, a protective pad, a hydraulic component, and a drive component. The rotating disk is rotatably mounted on the support ring, and the fixed seat is rotatably mounted on the support ring and symmetrically distributed with the rotating disk. The rotating disk and the fixed plate are symmetrically distributed inside the support ring. The protective pad is detachably mounted on the rotating disk, the hydraulic component is mounted on the rotating disk, and the drive component is disposed on the operating table.

[0008] The hydraulic assembly includes a first hydraulic cylinder and a second hydraulic cylinder. The fixed end of the first hydraulic cylinder is fixedly mounted on the rotating disk, and the free end of the first hydraulic cylinder is fixedly connected to the rotating disk. The fixed end of the second hydraulic cylinder is fixedly mounted on the fixed base, and the free end of the second hydraulic cylinder is fixedly connected to the fixed plate.

[0009] The drive assembly includes a micro motor and a connecting rod. The micro motor is mounted on the operating table, and the connecting rod is fixedly connected to the output end of the micro motor.

[0010] The drive assembly further includes a drive wheel and a driven wheel. The drive wheel is fixedly mounted on the side of the connecting rod away from the micro motor, and the driven wheel is fixedly mounted on the rotating disk. The drive wheel meshes with the driven wheel.

[0011] The hydraulic cylinder further includes a locking bolt and a resisting bolt, wherein the locking bolt abuts against the rotating disk and the resisting bolt abuts against the fixed seat.

[0012] This utility model discloses a surface grinding fixture for aluminum alloy parts. After the workpiece is placed between the rotating disk and the fixed plate, a hydraulic cylinder drives the rotating disk to move, and a hydraulic cylinder drives the fixed plate to move. The rotating disk and the fixed plate cooperate to clamp and fix the workpiece. When it is necessary to change the processing surface, the connecting rod is driven by the micro motor to rotate. The rotation of the connecting rod drives the driving wheel to rotate, the driving wheel drives the driven wheel to rotate, the driven wheel drives the rotating disk to rotate, and the rotating disk drives the hydraulic cylinder to rotate. The rotation of the hydraulic cylinder drives the rotating disk to rotate, and the rotation of the rotating disk drives the workpiece to rotate, thereby changing the processing surface of the workpiece.

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0019] Please see Figure 1-Figure 3 , Figure 1This is a schematic diagram of the surface grinding fixture for aluminum alloy parts according to this utility model. Figure 2 This is a schematic diagram of the rotating mechanism of the aluminum alloy part surface grinding fixture of this utility model. Figure 3 yes Figure 2 Enlarged view of point A.

[0020] This embodiment provides a surface grinding fixture for aluminum alloy parts, including an operating table 101, a grinding component 102, a support ring 103, an electric push rod 105, and a resisting plate 104, and a rotating mechanism. The rotating mechanism includes a rotating disk 106, a fixed plate 107, a rotating disk 108, a fixed base 109, a protective pad 110, a hydraulic component, and a drive component. The hydraulic component includes a first hydraulic cylinder 111 and a second hydraulic cylinder 112. The drive component includes a micro motor 113 and a connecting rod 114. The drive component also includes a driving wheel 115 and a driven wheel 116. The hydraulic cylinders also include a locking bolt 117 and a resisting bolt 118. The aforementioned solution solves the problem found in the use of existing devices where, after processing one surface of the workpiece, when processing other surfaces is required, the clamping component needs to be disassembled and the workpiece flipped over, and then the clamping component needs to be reinstalled before processing can continue, thus wasting both time and manpower.

[0021] In this embodiment, the grinding assembly 102 is disposed on the operating table 101, the support ring 103 is fixedly installed on the operating table 101, the electric push rod 105 is installed on the support ring 103, and the resisting plate 104 is installed on the electric push rod 105. The grinding assembly 102 includes an adjustment part, a positioning sleeve, an electric turntable, a support rod, a bearing, an electric linear slide, a second electric push rod 105, a drive part, a fixed frame, a drive motor, a fixed plate, a deburring brush, and other structures. This structure adopts the distance and connection method in the prior art document. The rotating plate 106 drives the workpiece to rotate, thereby changing the processing surface of the workpiece. No manual hand operation is required, saving manpower.

[0022] The rotating disk 108 is rotatably mounted on the support ring 103, and the fixed seat 109 is rotatably mounted on the support ring 103 and symmetrically distributed with the rotating disk 108. The rotating disk 106 and the fixed plate 107 are symmetrically distributed inside the support ring 103. The protective pad 110 is detachably mounted on the rotating disk 106. The hydraulic assembly is mounted on the rotating disk 106, and the drive assembly is located on the operating table 101. The protective pad 110 is installed on the side of the fixed plate 107 near the rotating disk 106. The protective pad 110 protects the workpiece while increasing the friction between the workpiece and the workpiece. During operation, the workpiece is placed between the rotating disk 106 and the fixed plate 107. Afterwards, the rotating disk 106, the fixed plate 107, and the resisting plate 104 cooperate to resist and fix the workpiece on the support ring 103. Then, the workpiece is polished by the grinding component 102. When it is necessary to change the processing surface, the resisting plate 104 disengages from the workpiece and drives the rotating disk 106 to rotate through the driving component. The rotation of the rotating disk 106 drives the workpiece to rotate, thereby changing the processing surface of the workpiece. No manual hand operation is required, saving manpower. This solves the problem found in the use of existing devices that, after processing one surface of the workpiece, when processing other surfaces is required, the clamping component must be disassembled and the workpiece flipped over, and the clamping component must be reinstalled before processing can continue, which wastes both time and manpower.

[0023] Secondly, the fixed end of the first hydraulic cylinder 111 is fixedly installed on the rotating disk 108, and the free end of the hydraulic cylinder is fixedly connected to the rotating disk 106. The fixed end of the second hydraulic cylinder 112 is fixedly installed on the fixed base 109, and the free end of the second hydraulic cylinder 112 is fixedly connected to the fixed plate 107. The first hydraulic cylinder 111 drives the rotating disk 106 to move, and the second hydraulic cylinder 112 drives the fixed plate 107 to move. The rotating disk 106 and the fixed plate 107 cooperate to move and clamp and fix the workpiece.

[0024] Furthermore, the micro motor 113 is mounted on the operating table 101, and the connecting rod 114 is fixedly connected to the output end of the micro motor 113, so that the connecting rod 114 can be rotated by the micro motor 113.

[0025] Meanwhile, the driving wheel 115 is fixedly installed on the side of the connecting rod 114 away from the micro motor 113, and the driven wheel 116 is fixedly installed on the rotating disk 108. The driving wheel 115 and the driven wheel 116 mesh with each other. The rotation of the connecting rod 114 drives the driving wheel 115 to rotate, the rotation of the driving wheel 115 drives the driven wheel 116 to rotate, and the rotation of the driven wheel 116 drives the rotating disk 108 to rotate.

[0026] In addition, the locking bolt 117 abuts against the rotating disk 108, the resisting bolt 118 abuts against the fixed seat 109, the support ring 103 has a threaded hole that matches the locking thread and the rotating disk 108, and the support ring 103 has a slot that matches the rotating disk 108 and the fixed seat 109. The threaded hole communicates with the slot. When it is necessary to process the side plate of the workpiece, the rotating disk 106 and the fixed plate 107 disengage from the workpiece, which facilitates the processing of the side. When it is necessary to process the other two sides, the resisting plate 104 disengages from the workpiece, and the workpiece is clamped and fixed by the rotating disk 106 and the fixed plate 107. At the same time, the resisting bolt 118 and the locking bolt 117 resist and fix the rotating disk 108 and the fixed seat 109, which improves the clamping stability.

[0027] When using the aluminum alloy surface grinding fixture described in this embodiment, after placing the workpiece between the rotating disk 106 and the fixed plate 107, the first hydraulic cylinder 111 drives the rotating disk 106 to move, and the second hydraulic cylinder 112 drives the fixed plate 107 to move. The rotating disk 106 and the fixed plate 107 cooperate to clamp and fix the workpiece. When it is necessary to change the processing surface, the connecting rod 114 is driven to rotate by the micro motor 113. The rotation of the connecting rod 114 drives the driving wheel 115 to rotate, and the rotation of the driving wheel 115 drives the driven wheel 116 to rotate. The driven wheel 116 rotates, driving the rotating disk 108 to rotate. The rotating disk 108 rotates, driving the hydraulic cylinder 111 to rotate. The rotating disk 106 rotates, driving the workpiece to rotate, thereby changing the workpiece's processing surface. This eliminates the need for manual hand operation, saving manpower. It also solves the problem found in existing devices where, after processing one surface of the workpiece, processing other surfaces requires disassembling the clamping assembly, flipping the workpiece, and reinstalling the clamping assembly before processing can continue, thus wasting both time and manpower.
