Description

Technical Field

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

[0002] In the injection molding process of gears, due to mold structure or process limitations, the center hole of the gear is often formed as a blind hole instead of a through hole. While this design simplifies the ejection mechanism of the mold or reduces manufacturing costs, it brings some problems in practical applications. First, the blind hole structure makes it difficult to achieve precise alignment of the gear during assembly, especially when it needs to mate with a metal shaft or other transmission components. The bottom of the blind hole may obstruct the complete insertion of the shaft, affecting assembly efficiency and transmission stability. Therefore, subsequent machining is required to make the blind hole a through hole. In existing technologies, solutions include directly forming a through hole by optimizing the mold design, but this significantly increases mold complexity and maintenance costs. Alternatively, in other solutions, the bottom of the blind hole is removed through subsequent machining.

[0003] However, the shortcomings of the existing technology are that the blind hole needs to be processed first to form a through hole, and then the edge of the through hole needs to be ground to form a chamfer structure. In the existing method, the workstations for these two processes are usually independent of each other, so the workpiece that has been punched needs to be moved to the chamfering and grinding workstation manually. As a result, the efficiency of the entire processing is low, and it may also damage the gear teeth. Since the work needs to be operated at different workstations, the position of the workpiece needs to be placed and adjusted manually, which may lead to deviations in processing accuracy and low processing accuracy.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Reference Figures 1 to 4 As shown, this utility model discloses a processing device for sequentially performing punching and chamfering operations on a workpiece 1.

[0029] In this embodiment, the workpiece 1 to be processed is a gear, and the purpose of the processing device is to form a through hole 10 at the axial position of the gear and to grind the edge of the through hole 10 to form a chamfer structure, thereby forming a product that meets the requirements.

[0030] Specifically, the processing device includes a support unit, which includes a base 20, a processing table 21, and a mounting platform 22. The processing table 21 is mounted on the base 20, and the workpiece 1 is detachably mounted on the processing table 21.

[0032] The processing device further includes a punching unit, which includes a first mounting base 30 and a punching assembly. The first mounting base 30 is connected to the mounting platform 22, and the punching assembly is movably disposed on the first mounting base 30. The punching assembly moves to the opposite side of the surface to be processed of the workpiece 1 and is driven to move along a second direction to perform a punching operation on the surface to be processed.

[0033] The second direction is perpendicular to the first direction.

[0034] The processing device further includes a chamfering unit, which includes a second mounting base 40 and a chamfering component 41. The second mounting base 40 is movably connected to the mounting platform 22, and the chamfering component is disposed on the second mounting base 40. The chamfering component 41 moves to the opposite side of the surface to be processed and is driven to move along the second direction to perform chamfering processing on the surface to be processed.

[0035] The processing device also includes a control unit, which is communicatively connected to the punching unit and the chamfering unit. The control unit can control the operation of the punching unit and the chamfering unit to sequentially punch and chamfer the workpiece 1. Specifically, the workpiece 1 is first punched to form the through hole 10, and then the edges of the through hole 10 are chamfered.

[0036] Therefore, it can be understood that the processing device protected by this utility model includes a supporting unit, a punching unit, and a chamfering unit. The supporting unit includes a processing table and a base. The workpiece to be processed can be fixed on the processing table. The punching unit and the chamfering unit are movably mounted on the base and can move along a first direction. Thus, according to processing requirements, the punching unit and the chamfering unit can be moved to corresponding positions to perform different types of processing on the workpiece.

In this way, even with the workpiece fixed in the same position, punching and chamfering processing can be performed separately. Using this device can improve processing efficiency, thereby effectively increasing output. Because the workpiece placement position is relatively stable, there is no need to frequently change positions, thus ensuring the processing dimensional accuracy and guaranteeing the stability of processing accuracy.

[0041] Furthermore, the distance between the first limiting rod 32 and the processing table 21 is less than the distance between the punching head 31 and the processing table. This arrangement allows for limiting the stroke of the punching head 31 during punching.

[0042] In a preferred embodiment, there are two first limiting rods 32, which are symmetrically arranged on both sides of the punching head 31.

[0043] In detail, the first mounting base 30 is provided with a first mounting hole and a second mounting hole along the second direction, the first limiting rod 32 is in clearance fit with the first mounting hole, and the punching head 31 is in clearance fit with the second mounting hole.

[0044] The first driving component includes, but is not limited to, a drive motor.

[0045] In a preferred embodiment, the mounting platform 22 is provided with a second driving member 220, and the second mounting base 40 is connected to the movable output end of the second driving member 220 so as to move along the second direction under the drive of the second driving member 220. The second driving member 220 includes, but is not limited to, a driving cylinder.

[0046] To ensure the stability of the second mounting base 40 when it moves along the second direction, the mounting platform 22 is provided with a second guide rail along the second direction, and a second slider is provided on the second guide rail, the second slider being connected to the second mounting base 40.

[0048] In order to limit the stroke of the chamfering cutter head 410 during chamfering, the distance between the second limiting rod 42 and the processing table 21 is greater than the distance between the chamfering cutter head 410 and the processing table 21.

[0049] The third driving component 411 includes, but is not limited to, a drive motor.

[0050] Specifically, the processing device further includes a fourth driving member 34, which is used to drive the mounting platform 22 to move. The active output end of the fourth driving member 34 moves along the first direction, thereby enabling the fourth driving member 34 to drive the mounting platform 22 to move along the first direction.

[0051] In a preferred embodiment, the mounting platform 22 has a connecting block 221 protruding in the horizontal direction, and the connecting block 221 is connected to the movable output end of the fourth driving member 34.

[0053] Specifically, the limiting block 201 is provided with a clearance hole, which can accommodate the passage of the movable output end of the fourth driving member 34. When the connecting block 221 moves under the drive of the fourth driving member 34 to abut against the limiting block 201, it can limit the stroke of the mounting platform 22.

[0054] In detail, the fourth driving component 34 includes, but is not limited to, a driving cylinder.
