Description

Technical Field

[0001] The utility model relates to the technical field of metal part processing machine tools, in particular to a double-sided processing combined machine tool. Background Technique

[0002] With the rapid development of new energy vehicles, as one of the core components of new energy vehicles, the demand for battery systems has increased sharply. The battery housing is one of the main components of the battery system, and its processing quality and stability directly determine the stability and reliability of the battery system.

[0003] The battery housing is mainly made of metal and plastic. Taking aluminum alloy in metal as an example, as a metal welded part, both the front and side of the battery housing need to be processed. In the existing processing methods, whether it is a vertical machining center or a horizontal machining center, different surfaces need to be processed sequentially. This kind of surface-by-surface processing first takes a long processing time; secondly, secondary clamping is required during surface change processing, which is likely to cause relative position errors, resulting in unstable product quality, being unfavorable for subsequent assembly, and affecting the assembly quality. Summary of the Utility Model

[0004] The applicant of the present utility model aims at the above-mentioned shortcomings in the existing production technology and provides a double-sided processing combined machine tool with a reasonable structure, which can simultaneously perform synchronous processing on the front and back sides of the same housing, improving the processing efficiency.

[0005] The technical solution adopted by the present utility model is as follows:

[0006] A double-sided processing combined machine tool includes a front section of the machine tool, a middle section of the machine tool, and a rear section of the machine tool. A conveyor belt runs through the front section, the middle section, and the rear section of the machine tool. The middle section of the machine tool is a processing position, and independent side cutting tools are slidably arranged on both sides of the processing position; a top wall cutting tool with three-way movement is arranged above the middle section of the machine tool.

[0007] The three-way movement of the top wall cutting tool (5) is specifically realized by the following structure:

[0008] Movement along the feeding direction: The lead screw drives the sliding along the rail, and the lead screw is recessed and arranged between two vertical rails. Movement perpendicular to the feeding direction: The lead screw drives the sliding along the rail, and the lead screw is located below the sliding member, and

[0009] the load-bearing of the sliding member falls on the supporting member.

[0010] Vertical movement: The lead screw or the air cylinder vertically pushes the top wall cutting tool.

[0011] The lead screw only exerts pushing and pulling forces on the structure.

[0012] All cutting tools are independent of each other and simultaneously process the same workpiece to be processed.

[0013] As a further improvement of the above technical solution:

[0014] On both sides of the conveyor belt in the middle section of the machine tool, linear guides are provided, and each linear guide drives a side cutting tool.

[0015] The side cutting tool is connected to the linear guide through a horizontal power head, and the side cutting tool reciprocates along the feeding direction.

[0016] A cross beam is provided above the middle section of the machine tool. A crane is slidably connected to the cross beam, and the movement path of the crane is perpendicular to the feeding path of the machine tool; the top wall cutting tool is connected to the crane.

[0017] In the initial state, the cranes are symmetrically arranged at both ends of the cross beam, and each crane is equipped with an independent power source.

[0018] The top wall cutting tool is a spare structure.

[0019] A column is connected between the cross beam and the machine tool to form a hollow support structure, and a feeding space and a tool feeding space are reserved.

[0020] The clamping station is located on one side of the feeding direction at the front section of the machine tool, and the disassembly station is located on one side of the discharging direction at the rear section of the machine tool.

[0021] During the processing, the relative position between the product to be processed and the tooling is constant.

[0022] The beneficial effects of the present utility model are as follows:

[0023] The structure of the present utility model is compact and reasonable, and the operation is convenient. It adopts a structure of simultaneous bilateral processing, replacing the conventional unilateral processing structure. While improving the processing efficiency, it can prevent the assembly precision deviation caused by secondary clamping, and thus ensure the precision quality of the output finished product.

[0024] In the present utility model, two clamping stations are provided on the main guide rail of the bed body, and each clamping station corresponds to an independent tool to complete the cutting on both sides; a crane cross beam is provided at the top, and the crane cross beam is equipped with a tool, which can move horizontally and longitudinally in the horizontal plane and also has a cutting function.

[0031] The following combines with the drawings to illustrate the specific embodiments of the present utility model.

[0032] As Figure 1 shown, the double-sided machining combination machine tool of this embodiment includes a front section 1, a middle section 2 and a rear section 3 of the machine tool. A conveyor belt runs through the front section 1, the middle section 2 and the rear section 3 of the machine tool. The middle section 2 of the machine tool is the machining position, and independent side cutting tools 4 are slidably arranged on both sides of the machining position; a top wall cutting tool 5 with three-way movement is arranged above the middle section 2 of the machine tool.

[0033] The three-way movement of the top wall cutting tool (5) is specifically realized by the following structure:

[0034] Moving along the feeding direction: The lead screw drives the sliding along the rail. The lead screw is recessed between two vertical rails. Moving along the direction perpendicular to the feeding direction: The lead screw drives the sliding along the rail. The lead screw is located below the sliding member, and

[0035] the load-bearing of the sliding member falls on the support member.

[0036] Moving in the vertical direction: The lead screw or the air cylinder vertically pushes the top wall cutting tool 5.

[0037] The lead screw only exerts pushing and pulling forces on the structure.

[0038] All cutting tools are independent of each other and process the same workpiece to be machined simultaneously.

[0039] Linear guides 101 are arranged on both sides of the conveyor belt in the middle section 2 of the machine tool, and each linear guide 101 drives a side cutting tool 4.

[0040] The side cutting tool 4 is connected to the linear guide 101 through a horizontal power head, and the side cutting tool 4 reciprocates along the feeding direction.

[0041] A cross beam 201 is arranged above the middle section 2 of the machine tool. An overhead crane 202 is slidably connected to the cross beam 201. The movement path of the overhead crane 202 is perpendicular to the machine tool feeding path; the top wall cutting tool 5 is connected to the overhead crane 202.

[0042] In the initial state, the overhead cranes 202 are symmetrically arranged at both ends of the cross beam 201, and each overhead crane 202 is equipped with an independent power source.

[0043] The top wall cutting tool 5 is a spare structure.

[0044] A column 205 is connected between the cross beam 201 and the machine tool to form a hollow support structure, reserving a feeding space and a tool feeding space.

[0045] The clamping station is located on one side of the feeding direction of the front section 1 of the machine tool, and the disassembly station is located on one side of the discharging direction of the rear section 3 of the machine tool.

[0046] During the machining process, the relative position between the product to be machined and the tooling is constant.

[0047] The specific structure and working principle of the present utility model are as follows:

[0048] As Figures 1-5 shown, compared with a conventional machine tool, especially a conventional machine tool for machining a battery case, the biggest improvement of the double-sided machining combination machine tool of the present utility model is that a plurality of cutting tool positions are provided on the same machine tool, and these cutting tool positions all serve the same clamping station to perform cutting on the same battery case.

[0049] A machine tool is divided into three sections according to the feeding direction, namely a front section 1, a middle section 2 and a rear section 3. Among them, the main functions of the front section 1 and the rear section 3 are to add sensors and cleaning brushes on the linear guide 101 for detection and cleaning. In the present utility model, no major improvements are made to these two links, so they will not be elaborated here.

[0050] The synchronous cutting machining of the middle section 2 is the key point of improvement of this solution. The clamping station is arranged on the conveyor belt of the machine tool. When the clamping station carries the product to be machined to the expected machining position, the side cutting tools 4 on both sides perform double-sided simultaneous tool feeding cutting on the product to be machined, that is, the battery case.

[0051] The advantage of this solution is also that a cross beam 201 is further arranged directly above the middle section 2 of the machine tool. A crane 202 is arranged on the cross beam 201, and a third group of cutting tools, namely the top wall cutting tool 5, is arranged on the crane 202. For the convenience of distinction, the feeding direction is defined as the x direction, the moving direction of the crane 202 on the cross beam 201 is the y direction, and the top wall cutting tool 5 can reciprocate in the x direction and the z direction to cooperate with the side cutting tool 4 to perform cutting on the battery case. If the battery case only needs to be machined on both sides and the top wall in the clamped state does not need to be machined, or the two side cases do not need auxiliary machining, then the top wall cutting tool 5 is in a braking state and does not work.

[0052] The cranes 202 are also symmetrically arranged on both sides of the cross beam 201, that is, two groups of top wall cutting tools 5 are arranged at the top. The two groups of top wall cutting tools 5 are independent of each other, and the power sources of the two side cranes 202 are also independent of each other, that is, the two groups of top wall cutting tools 5 can be adjusted in position according to the actual working conditions for auxiliary machining.

[0053] All the above-mentioned movements can be driven and realized by commercially available power devices such as cylinders and lead screws.

[0054] After the battery housing is processed, all the cutting tools retract, the conveyor belt continues to output the finished battery housing, and it is cleaned, inspected and stored in the later stage 3.

[0055] The advantage of the present utility model is that it only needs to clamp the product to be processed once during loading. When processing the same battery housing subsequently, there is no need to disassemble and reassemble the product again, ensuring the clamping accuracy and processing accuracy.

[0056] In the present utility model, two ideas are provided. One is that there is only one clamping station on a conveyor belt, and the side cutting tools 4 on both sides process the same product. If the processing requirements are high, the top wall cutting tool 5 also performs auxiliary processing.

[0057] The other is that there are two clamping stations arranged on a conveyor belt. The side cutting tools 4 on both sides process the corresponding processing surfaces respectively, and the top wall cutting tool 5 on the top assists in processing the remaining two surfaces of the two products, that is, the opposite surfaces of the two products are processed by the top wall cutting tool 5, and the back surfaces of the two products are processed by the side cutting tools 4.

[0058] Therefore, the present utility model has made remarkable progress in terms of improving processing efficiency, applicable working conditions, clamping and cutting accuracy.
