[0033] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] This technical solution provides a precision machining production line for automobile engine gearbox covers, including a rough-finished product turnover table 21, a first precision machining equipment 22, a precision semi-finished product transfer table 23, a second precision machining equipment 24, a cleaning tank 25, a discharge conveyor belt 26, and a precision machining transfer robot 27. The rough-finished product turnover table 21, the first precision machining equipment 22, the precision semi-finished product transfer table 23, the second precision machining equipment 24, the cleaning tank 25, and the discharge conveyor belt 26 are all located within the transfer range of the precision machining transfer robot 27.

[0035] The first finishing equipment 22 is used to finish the first surface 31 of the workpiece 3;

[0036] The second finishing equipment 24 is used to finish the second surface 32 of the workpiece 3.

[0037] To improve the efficiency and quality of precision machining of automotive engine transmission covers, this technical solution proposes a precision machining production line for automotive engine transmission covers, such as... Figure 1-4 As shown, by adding a precision machining transfer robot to transfer the products to be processed between various equipment in the precision machining process, it is beneficial to optimize the layout of the precision machining production line, thereby improving the precision machining efficiency and processing quality of the automobile engine gearbox cover, and overcoming the shortcomings of the existing technology.

[0038] Specifically, the finishing production line of this solution includes a rough-finished product turnover table 21, a first finishing equipment 22, a finishing semi-finished product transfer table 23, a second finishing equipment 24, a cleaning box 25, a discharge conveyor belt 26, and a finishing transfer robot 27. Since the finishing process of the automotive engine gearbox cover requires processing the first surface 31 first, followed by the second surface 32, this solution adds a turnover function to the transfer table (i.e., the rough-finished product turnover table 21) connecting the rough-finishing and finishing steps to facilitate the smooth progress of subsequent processes. The workflow of the finishing production line in this solution is as follows: The first surface 31 of the workpiece 3 is flipped upward using the roughing finished product flipping table 21, and then the finishing transfer robot 27 is used to transfer the workpiece between the roughing finished product flipping table 21, the first finishing equipment 22, the finishing semi-finished product transfer table 23 and the second finishing equipment 24 in sequence to complete the finishing of the first surface 31 and the second surface 32 (including milling, drilling and boring steps); finally, after being cleaned by the cleaning box 5, the workpiece is placed on the discharge conveyor belt 26 for unloading.

[0039] It should be noted that the first finishing equipment 22 and the second finishing equipment 24 in this solution are both existing special-purpose processing equipment, and their structures will not be described in detail here.

[0040] Furthermore, the finishing production line also includes a ground rail 28, the finishing transfer robot 27 is installed on the ground rail 28, and the finishing transfer robot 27 moves along the extension direction of the ground rail 28;

[0041] The rough-processed finished product turning table 21 is located near one end of the ground rail 28, and the discharge conveyor belt 26 is located near the other end of the ground rail 28;

[0042] Two of each of the first finishing equipment 22 and the second finishing equipment 24 are provided; the two first finishing equipment 22 are provided on both sides of the ground rail 28 along the extension direction, and the first finishing equipment 22 is provided close to the rough finished product turning table 21; the two second finishing equipment 24 are provided on both sides of the ground rail 28 along the extension direction, and the second finishing equipment 24 is provided close to the discharge conveyor belt 26.

[0043] In addition, such as Figure 1-2 As shown, in order to further improve the processing efficiency of automobile engine gearbox cover, this solution also adds two sets of precision processing equipment (a first precision processing equipment 22 and a second precision processing equipment 24 constitute one set of precision processing equipment) to the precision processing production line, and widens the transfer range of the precision processing transfer robot 27 through the ground rail 28, so that the steps of the precision processing production line can be matched and coordinated with each other.

[0044] To further explain, the rough-processed finished product turning table 21 includes a housing 211, a turning fixture 212, and a rotating fixture 213;

[0045] The flipping fixture 212 is rotatably mounted inside the housing 211, and the rotation axis of the flipping fixture 212 extends horizontally, with the rotation axis of the flipping fixture 212 located at the edge of the flipping fixture 212.

[0046] The rotating fixture 213 is installed inside the housing 211, and the rotating fixture 213 is located diagonally below the flipping fixture 212.

[0047] like Figure 3 As shown, the rough-machined finished product turning table 21 of this solution includes a box 211, a turning fixture 212 and a rotating fixture 213. The workpiece 3 to be turned is placed on the turning fixture 212, and the workpiece 3 is clamped and stabilized by the turning fixture 212 before being turned. After the workpiece 3 is turned into place, the clamping of the workpiece 3 by the turning fixture 212 is released first, and the workpiece 3 is placed on the top of the rotating fixture 213. Finally, the turning fixture 212 is reset, and the turning of the workpiece 3 is completed.

[0048] To further explain, the rotating fixture 213 can be rotatably installed inside the housing 211 along its own axis, and the rotation axis of the flipping fixture 212 extends vertically;

[0049] The side wall of the housing 211 is provided with a clearance position 2111, and the clearance position 2111 is located close to the rotating tooling 213. The clearance position 2111 is used to avoid the finishing transfer robot 27.

[0050] Furthermore, in order to facilitate the material handling of the precision machining transfer robot 27, the rotating fixture 213 of this solution can also rotate along its own axis to accommodate the material handling angle of the precision machining transfer robot 27.

[0051] To further explain, the rough-processed finished product turning table 21 includes a spray head and a water receiving tank 214. The inlet of the spray head is connected to a water source, and the outlet of the spray head is located inside the upper part of the box body 211. Multiple spray heads are provided, and the multiple spray heads are evenly distributed around the edge of the box body 211.

[0052] The bottom center of the box 211 has a drain outlet 2112, and the water receiving tank 214 is located below the drain outlet 2112.

[0053] Furthermore, since the surface of the product after rough processing will have debris, in order to improve the processing accuracy of fine processing, this solution can use a spray head (not shown in the figure) to clean the rough processed finished product in the rough processed finished product turnover table 21, and add a water receiving tank 214 in the rough processed finished product turnover table 21 to catch the cleaning wastewater.

[0054] To further explain, the water receiving tank 214 includes a filter plate 2141 and a water receiving plate 2142 arranged sequentially from top to bottom, and the bottom of the filter plate 2141 has a plurality of evenly distributed filter holes.

[0055] As a preferred embodiment of the above, the water receiving tank 214 includes a filter plate 2141 and a water receiving plate 2142 arranged sequentially from top to bottom. The filter plate 2141 can filter debris and prevent debris from causing blockage.

[0056] To further explain, the precision machining transfer robot 27 includes a six-axis manipulator 271, a fixed plate 272, and clamping members 273. The fixed plate 272 is installed at the output end of the six-axis manipulator 271, and there are two clamping members 273, which are respectively installed on both sides of the fixed plate 272.

[0057] like Figure 4 As shown, the precision machining transfer robot 27 of this solution includes a six-axis manipulator 271, a fixed plate 272 and two clamping parts 273, and the two clamping parts 273 are respectively installed on both sides of the fixed plate 272, which helps to speed up the loading and unloading speed of each piece of equipment in the precision machining production line.

[0058] In one specific embodiment, when the first finishing equipment 22 contains a finished product A, and the finishing transfer robot 27 holds a product B that is about to enter the first finishing equipment 22 for processing, the finishing transfer robot 27 can use the remaining gripper 273 that does not hold any product to first remove product A from the first finishing equipment 22, and then immediately place product B inside the first finishing equipment 22 for processing, thereby speeding up the loading and unloading speed of each device in the finishing production line and improving the processing efficiency of the finishing production line.

[0059] To further explain, the clamping member 273 includes a three-jaw positioning clamp 2731 and a linear clamp 2732. The three-jaw positioning clamp 2731 and the linear clamp 2732 are distributed at intervals on one side of the fixing plate 272. The clamping surface of the three-jaw positioning clamp 2731 is used to abut against the positioning hole 33 of the workpiece 3, and the clamping surface of the linear clamp 2732 is used to abut against the side wall of the workpiece 3.

[0060] To improve the versatility of the clamping component 273, allowing the clamping component 273 to have either the first side 31 or the second side 32 of the workpiece 3 facing inwards during the clamping process, this solution also optimizes the structure of the clamping component 273. First, the three-jaw positioning fixture 2731 is used to abut and position the positioning hole 33 of the workpiece 3, and then the linear fixture 2732 is used to clamp and position the side wall of the workpiece 3, so as to clamp both sides of the workpiece 3 at the same time.

[0061] To further explain, the three-jaw positioning fixture 2731 includes a mounting post 27311 and three clamping blocks 27312. The three clamping blocks 27312 are circumferentially arranged on the top of the mounting post 27311 along the central axis of the mounting post 27311, and the three clamping blocks 27312 simultaneously move closer to and away from the central axis of the mounting post 27311.

[0062] The linear clamp 2732 includes a linear cylinder 27321 and a clamping plate 27322. The clamping plate 27322 is installed at the output end of the linear cylinder 27321, and the clamping plate 27322 moves closer to and further away from the three-jaw positioning clamp 2731 through the linear cylinder 27321.

[0063] Specifically, the three-jaw positioning fixture 2731 of this solution includes a mounting post 27311 and three clamping blocks 27312. When the three clamping blocks 27312 move away from the central axis of the mounting post 27311 simultaneously, the clamping blocks 27312 can abut against the positioning hole 33. The linear fixture 2732 of this solution includes a linear cylinder 27321 and a clamping plate 27322. When the clamping plate 27322 moves towards the three-jaw positioning fixture 2731, the clamping plate 27322 can abut against the side wall of the workpiece 3.

[0064] Furthermore, both the clamping surfaces of the three-jaw positioning fixture 2731 and the linear fixture 2732 are provided with anti-slip rubber 2733. This increases the friction between the clamping surfaces and the workpiece 3, preventing the workpiece 3 from slipping out of the clamp.
