Description

Technical Field

[0001] This utility model relates to the field of machine tool fixture technology, specifically to a fixing fixture for the outer side of a new energy motor housing. Background Technology

[0002] With the development of new energy vehicles, the performance of vehicle drive motors has also improved by leaps and bounds. Consequently, the requirements for the structural strength and machining precision of motor housings are becoming increasingly stringent. Currently, the weight and volume of motor housings have significantly increased. At present, machine tools still use one or two chucks to fix the motor housing and align it for machining. However, due to changes in the machining precision and strength of motor housings, one or two chucks alone are no longer sufficient to meet the requirements for stable fixing of the motor housing. Because the machine tool applies a large force to the motor housing during machining, the motor housing is prone to displacement during machining, leading to machining errors. Utility Model Content

Detailed Implementation

[0018] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Example

[0020] Combined with appendix Figure 1-3A new energy motor housing outer side fixing fixture includes a machine tool fixing base 1. The machine tool fixing base 1 includes a support frame 2 fixedly mounted on it. A rotating chuck 3 is rotatably mounted on the support frame 2. A machine tool spindle 4 extending out of the support frame 2 is rotatably mounted on the support frame 2. The machine tool spindle 4 extending out of the support frame 2 is fixedly connected to the rotating chuck 3. After the machine tool fixing base 1 is installed in the processing machine tool, the machine tool spindle 4 can drive the rotating chuck 3 to rotate.

[0021] A fixed fixture 5 is fixedly mounted on the rotary chuck 3. The fixed fixture 5 includes a mounting plate 6, which is vertically arranged. The mounting plate 6 has a retaining block for engaging with the rotary chuck 3. The rotary chuck 3 engages with the retaining block, thereby fixing the fixed fixture 5 to the machine tool base 1. The machine tool spindle 4 can drive the rotary chuck 3 to rotate, thereby driving the fixed fixture 5 to rotate, thus adjusting the position of the parts mounted on the fixed fixture, facilitating multi-angle machining.

[0022] Various clamps are mounted on the mounting plate 6, and the motor housing 8 is mounted on the fixing clamp 5. The motor housing 8 is fastened to the mounting plate 6 with its open side facing the mounting plate 6. The mounting plate 6 is equipped with various clamps to fix the motor housing 8 to the fixing clamp 5. The motor housing 8 is a hollow housing with one side being an open opening, the interior of which is the cavity of the motor housing 8. The other side of the motor housing 8 does not have an opening, but only has a shaft hole on the housing surface.

[0023] Mounting plate 6 is fixedly equipped with two types of clamps: several sets of limiting clamps 9 and several pressing clamps 10. Both limiting clamps 9 and pressing clamps 10 are hydraulic cylinders used to fix parts. The hydraulic cylinder of the limiting clamp 9 is equipped with a supporting cylinder 11. The hydraulic cylinder is driven by hydraulic oil and can rotate to abut against the motor housing 8 and press it. The supporting cylinder 11 is hydraulically driven to push out the cylinder. Through the pressing of the hydraulic cylinder and the pushing out of the supporting cylinder, the limiting clamp 9 can lock the motor housing 8, thereby achieving the purpose of fixing the motor housing. The support cylinder 11 is set in correspondence with the hydraulic angle cylinder. Each hydraulic angle cylinder has a corresponding support cylinder 11 at its pressing position. The support cylinder 11 can counteract the pressing force of the hydraulic angle cylinder, thereby preventing the motor housing 8 from deforming at the contact point with the hydraulic angle cylinder due to excessive pressure from a single hydraulic angle cylinder. By supporting the motor housing 8 on the opposite side of the contact surface between the motor housing 8 and the hydraulic angle cylinder with the support cylinder 11, the pressure of the hydraulic angle cylinder is balanced, preventing deformation of the motor housing.

[0024] The pressing and fixing clamp 10 is fixed on the mounting post 12, which is fixed on the mounting plate 6. The mounting post 12 is used to extend the installation position of the pressing and fixing clamp 10 so that there is a certain distance between it and the mounting plate 6. The pressing and fixing clamp 10 directly abuts against the outer surface of the side of the motor housing 8 without an opening, thereby pressing the motor housing 8 as a whole by the pressing and fixing clamp 10, thereby fixing the motor housing 8.

[0025] The mounting plate 6 is also equipped with positioning plugs 13, which consist of a base and positioning pins. The base of the positioning plug 13 is fixed to the mounting plate 6, and the installation position of the base corresponds to the position of the through hole on the open end face of the motor housing 8. The positioning pin is fixed to the base and can be inserted into the insertion hole on the open end face of the motor housing 8. By inserting multiple positioning pins into different insertion holes on the open end face of the motor housing 8, the motor housing 8 is positioned. When the motor housing 8 is fastened onto the fixing clamp 5 with the opening facing the mounting plate 6, the multiple through holes on the open end face of the motor housing 8 correspond one-to-one with the positioning pins, thereby enabling the positioning plugs 13 to position the motor housing 8 and prevent it from deflecting during the fixing process. The positioning plugs 13 are preferably installed in pairs, with different sizes of bases and positioning pins on the bases of the two positioning plugs 13, so that the positioning pins of the two positioning plugs can be inserted into through holes of different sizes on the motor housing 8. The through holes on the open end face of the motor housing 8 are generally used for the assembly of the motor housing 8, and the through holes are generally bolt holes or screw holes.

[0026] Multiple limiting and fixing clamps 9, pressing and fixing clamps 10, and positioning plugs 13 are provided on the mounting plate 6. The distribution of multiple limiting and fixing clamps 9, pressing and fixing clamps 10, and positioning plugs 13 is designed to ensure that the motor housing 8 is evenly stressed. Under the premise of making full use of the installation space of the mounting plate 6 and ensuring that the motor housing 8 is evenly stressed, multiple limiting and fixing clamps 9, pressing and fixing clamps 10, and positioning plugs 13 can be evenly arranged around the motor housing 8, or diagonally arranged around the geometric center of the motor housing 8, or centered along the side of the mounting plate 6, or respectively arranged at the top corner of the mounting plate 6.

[0027] The mounting plate 6 is also equipped with several internal cavity support cylinders. The internal cavity support cylinders are used to be inserted into the internal cavity of the motor housing. Multiple internal cavity support cylinders are fixedly installed on the mounting plate. The internal cavity support cylinders abut against the inner bottom surface of the motor housing on the side with the opening. The internal cavity support cylinders avoid the shaft hole of the motor housing. The internal cavity support cylinders can prevent the motor housing from deforming when the outer surface of the motor housing is processed.

[0028] The support cylinder has the following functions: it can improve the stability of the fixture supporting the part, support the workpiece at multiple points, effectively distribute the weight of the workpiece and the forces generated during processing, reduce workpiece deformation, and ensure machining accuracy. During part machining, it can prevent deformation caused by gravity and cutting forces.

[0029] Enhanced positioning accuracy: The support cylinder can precisely control the support position and force. Combined with the positioning elements of the fixture, it can achieve more accurate positioning, which helps to improve the consistency of workpiece processing.

[0030] It can adapt to workpieces of different shapes and sizes. By adjusting the position and extension length of the auxiliary support cylinder, it can accommodate workpieces of various shapes and sizes, thus improving the versatility and flexibility of the fixture.

[0031] The support cylinder also compensates for manufacturing errors in the workpiece. For workpieces with manufacturing errors, the auxiliary support cylinder can automatically adjust the support force and position according to the actual situation to achieve good fit and support, and ensure processing quality.

[0032] Improving the machinability and rationally arranging the auxiliary support cylinders can make the workpiece more evenly stressed during processing, which is conducive to improving processing efficiency and tool life, and reducing processing costs.

[0033] The various types of clamps on the fixed fixture 5 are all driven by hydraulic oil, which is suitable for machining applications that require large clamping force and high precision. At the same time, they have a large force application and bearing capacity, making them suitable for fixing larger and heavier parts. They can achieve the best fixing effect on the machine tool housing 9 and ensure the machining accuracy of the machine tool.

[0034] Several air outlets 16 can be fixedly installed on the mounting plate 6. The air outlets 16 are installed on the machining position of the motor housing 9, so that when the motor housing 9 is machined, they can play the role of chip removal, thereby preventing machining chips from affecting the machine tool's machining of the motor housing 9.

[0035] The mounting plate 6 is evenly equipped with positioning surface air detection components. After the motor housing 8 is fixed, the air tightness result of the positioning surface air detection components is used to determine whether the part is positioned in place. The hydraulic cylinder fixture is equipped with hydraulic cylinder release detection components to ensure the pressure of the hydraulic cylinder fixture. The above air detection method is realized by the machine tool SMC air detection component. The positioning surface air tightness detection determines whether the part is positioned in place, and the hydraulic cylinder release detection determines whether the release is in place to ensure the requirements of automated detection. The positioning surface air detection components can be directly installed on the positioning pin of the positioning plug 13 or the inner cavity support hydraulic cylinder, so as to facilitate the air tightness detection of the contact surface and ensure the stability of the part.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
