Description

Technical Field

[0001] This utility model relates to a tooling for batch processing of compressor front covers, belonging to the technical field of compressor parts production equipment. Background Technology

[0002] One common type of compressor used in automotive air conditioning is the scroll compressor. The threaded holes on its front cover are typically M5 size. Currently, these holes are usually drilled manually. Specifically, a fitter uses a bench drill to hold the workpiece and drill the hole first, then uses a tapping machine to tap the remaining thread. This manual drilling method is flexible, allowing holes to be drilled in specific locations according to the needs of different compressor models. However, manual drilling is not only physically demanding and inefficient, but it also requires a high level of skill from the worker, making it difficult to replace them. The processing quality is inconsistent and heavily influenced by the worker's skill level. Utility Model Content

[0003] The purpose of this utility model is to provide a tooling for batch processing of compressor front covers, so as to improve production efficiency, ensure processing quality, and solve the technical problems of high labor intensity and unstable processing quality of manual drilling in the prior art.

[0004] The present invention adopts the following technical solution: a tooling for batch processing compressor front covers, comprising a cylinder support seat and a workpiece support seat fixed at intervals on a machine tool worktable. The cylinder support seat includes a cylinder support plate perpendicular to the horizontal plane, and the workpiece support seat includes a workpiece support plate arranged parallel to and spaced apart from the cylinder support plate. Positioning baffles are horizontally spaced on the workpiece support plate. Two adjacent positioning baffles are used to clamp a workpiece, and the space between two adjacent positioning baffles is a workstation. Cylinders are spaced apart on the cylinder support plate, each cylinder corresponding to each workstation. The piston rod of each cylinder faces each workstation, and the piston rod is used to press against the workpiece in the corresponding workstation.

[0005] The positioning baffle and the cylinder are both fixed to the workpiece support plate and the cylinder support plate respectively by bolts.

[0006] The workpiece support plate and the cylinder support plate are respectively provided with transverse holes at the positions of the bolts. The bolts are used to move within the transverse holes to change the fixed position of the positioning baffle or the cylinder.

[0007] Both the cylinder support base and the workpiece support base include a base fixed on the machine tool worktable, and both the cylinder support plate and the workpiece support plate are fixed on the base.

[0008] The cylinder support base is fixed with a bottom support bar. The bottom support bar extends horizontally along the arrangement direction of the workpiece support plate. The bottom support bar is spaced apart below the workpiece support plate and is used to support the bottom of the workpiece.

[0009] The positioning baffle is a T-shaped plate, which includes a horizontal plate and a vertical plate fixed together vertically. The horizontal plate and the workpiece support plate are arranged in parallel and spaced apart, and the vertical plate is connected between the horizontal plate and the workpiece support plate.

[0010] The piston rod end of the cylinder is fixed with a clamping platform for clamping the workpiece.

[0011] There are two sets of workpiece support seats, which are symmetrically arranged on both sides of the cylinder support plate. A cylinder is fixed on both sides of the cylinder support plate.

[0012] Each workpiece support has 5 positioning baffles, and each side of the cylinder support plate has 4 cylinders.

[0013] The beneficial effects of this utility model are: This utility model clamps and positions a workpiece by two adjacent positioning baffles, and then the piston rod of the cylinder presses the workpiece to fix it in the work station. Then, the machine tool is used to drill and tap the workpiece. After the thread hole is processed, the cylinder is released and the workpiece is taken out. Compared with the manual operation of the prior art, this utility model has the following advantages: (1) The tooling of this utility model can automatically complete the drilling and tapping operations with one machine tool. Each part reduces the amount of operation and does not need to be held by hand. Therefore, the labor intensity is greatly reduced and the production efficiency is greatly improved. (2) After the workpiece is fixed, this utility model uses a machine tool for processing, which can effectively ensure the processing quality. It is not affected by the skill level of the person. The substitutability of employees is enhanced. Employees who have received simple training can operate easily and are not limited by technical jobs. (3) The tooling of this utility model is suitable for mass production. The tooling station can be flexibly increased according to the length of the machine tool worktable and actual needs, thereby increasing the number of parts processed at one time and improving the processing efficiency. (4) Existing technology requires manual brushing of cutting fluid during fitter processing, resulting in aluminum chips and cutting fluid spilling and making the entire workstation dirty and messy. This utility model eliminates the fitter position and greatly improves the 5S on site.

[0014] Preferably, the left and right positions of the positioning baffle can be changed by altering the fixing position of the bolt in the transverse hole, thereby allowing for flexible adjustment of the workstation according to the size of the workpiece. Therefore, the fixture in this embodiment can accommodate workpieces of the same size or workpieces of different sizes.

[0015] Preferably, the bottom support bar provides bottom support for the workpiece, making the workpiece positioning and clamping more stable.

[0016] Preferably, the clamping table is in direct contact with the workpiece to avoid the cylinder directly clamping the workpiece and damaging the workpiece surface.

[0017] Preferably, a cylinder and a workpiece support are respectively provided on both sides of the cylinder support plate, which can increase the number of tooling stations and further improve processing efficiency. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 As shown, an embodiment of the present invention discloses a tooling for batch processing compressor front covers, comprising a cylinder support 2 and a workpiece support 1 fixed at intervals on a machine tool worktable. The cylinder support 2 includes a cylinder support plate 2.1 perpendicular to the horizontal plane, and the workpiece support 1 includes a workpiece support plate 1.1 parallel to and spaced apart from the cylinder support plate 2.1. Positioning baffles 1.2 are horizontally spaced on the workpiece support plate 1.1, and two adjacent positioning baffles 1.2 are used to clamp a workpiece 4, with the space between two adjacent positioning baffles 1.2 forming a workstation 4. Cylinders 3 are spaced apart on the cylinder support plate 2, each cylinder 3 corresponding to each workstation, and the piston rod of each cylinder 3 facing each workstation, the piston rod being used to press against the workpiece 4 in the corresponding workstation. A pressing platform 3.1 for pressing against the workpiece 4 is fixed to the end of the piston rod of the cylinder 3.

[0022] The positioning baffle 1.2 is a T-shaped plate, which includes a horizontal plate 1.21 and a vertical plate 1.22 fixed together vertically. The horizontal plate 1.21 and the workpiece support plate 1.1 are arranged parallel to each other and spaced apart. The vertical plate 1.22 is connected between the horizontal plate 1.21 and the workpiece support plate 1.1. The positioning baffle 1.2 and the cylinder 3 are both fixed to the workpiece support plate and the cylinder support plate 2.1 respectively by bolts. Horizontal holes 5 are respectively opened on the workpiece support plate 1.1 and the cylinder support plate 2.1 at the positions corresponding to the bolts. The bolts 6 are used to move within the horizontal holes 5 to change the fixed position of the positioning baffle 1.2 or the cylinder 3.

[0023] Both the cylinder support 2 and the workpiece support 1 include a base 7 fixed to the machine tool worktable, and the cylinder support plate 2.1 and the workpiece support plate 1.1 are fixed to the base 7. A bottom support strip 1.3 is fixed to the base of the cylinder support 2. The bottom support strip 1.3 extends horizontally along the arrangement direction of the workpiece support plate 1.1, and the bottom support strip 1.3 is spaced apart below the workpiece support plate 1.1. The bottom support strip 1.3 is used to support the bottom of the workpiece 4.

[0024] In this embodiment, there are two sets of workpiece support seats 1, symmetrically arranged on both sides of the cylinder support plate 2.1. Cylinders 3 are fixed to both sides of the cylinder support plate 2.1. Each workpiece support seat 1 has five positioning baffles 1.2, with each side forming four workstations. Each side of the cylinder support plate 2.1 has four cylinders. The eight cylinders respectively press against the workpieces 4 within the eight workstations. The two sets of workpiece support seats and one set of cylinder support seats are fixedly connected to the machine tool worktable. The positioning baffle in the middle of each workpiece support plate is immovable; its bolt is screwed into a threaded hole. The positions of the other positioning baffles are movable. By changing the fixing position of the bolt in the horizontal hole, the left and right positions of the positioning baffles can be changed, allowing for flexible adjustment of the workstations according to the size of the workpiece. Therefore, the fixture in this embodiment can accommodate workpieces of the same size or workpieces of different sizes.

[0025] In operation, the air inlets of each cylinder's air valve are connected in parallel to the air valve's output port via flexible hoses, and the air outlets of each cylinder are connected in parallel to the air valve's input port via flexible hoses. After the positioning baffle positions the workpiece, the air valve is activated, causing the piston rod of the cylinder to extend or retract, thus clamping and releasing the workpiece. The pressure of the air valve is set by a pressure gauge. While the workpiece is clamped, the machine tool performs drilling and tapping operations on the workpiece. After the threaded hole is machined, the cylinder is released to remove the workpiece.

[0026] The tooling in this embodiment is suitable for mass production. Compared with the existing technology where fitters use two processes—drilling with a drill and tapping with a tapping machine (requiring a fitter to manually operate each part twice)—this tooling can be completed automatically with a single machine tool. Each part requires one less operation and no manual handling is needed, thus significantly reducing labor intensity and increasing production efficiency. Furthermore, machine tool processing effectively ensures processing quality, is unaffected by human skill level, and enhances employee substitutability. Employees with minimal training can easily operate the tooling, eliminating the limitation of skilled trades. The tooling station can be flexibly increased according to the length of the machine tool's worktable and actual needs, thereby increasing the number of parts processed at one time and improving processing efficiency. Existing technology requires manual application of cutting fluid during fitter processing, resulting in aluminum chips and cutting fluid spillage, making the entire workstation dirty and messy. This invention eliminates the fitter's position, greatly improving the 5S (Sort, Set in order) on-site practices.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
