Description

Technical Field

[0001] This utility model pertains to auxiliary equipment for CNC machine tool processing, specifically relating to a fixture for machining the hub mounting holes at both ends of an electric forklift drive axle. Background Technology

[0002] The drive axle is a mechanism located at the end of the transmission system that changes the speed and torque from the transmission and transmits them to the drive wheels. A drive axle typically consists of a final drive, differential, wheel drivetrain, and drive axle housing; steering drive axles also include constant velocity joints. Furthermore, the drive axle must withstand vertical, longitudinal, and lateral forces acting between the road surface and the vehicle frame or body, as well as braking torque and reaction forces. Utility Model Content

[0003] Purpose of the utility model: The present utility model aims to provide a fixture for machining the hub mounting holes at both ends of the drive axle of an electric forklift. It is a special fixture for machining the axle housing of the drive axle of an electric forklift, which can solve the defects of existing CNC machine tools in machining the axle housing and in not being able to ensure that it is in a horizontal position.

[0004] Technical solution: A fixture for machining hub mounting holes at both ends of an electric forklift drive axle, comprising a base, on both sides of which are provided support seats. A support frame and a limiting mechanism for supporting and fixing the drive axle are provided on the support seats. The limiting mechanism limits the highest position of the drive axle on the support frame by limiting rods that can extend and retract downwards. The limiting mechanism includes controlling the drive axle to be horizontal by adjusting the limiting rods on both sides and clamping the drive axle in the limiting rods and the support frame.

[0005] The device is also equipped with a bracket based on the support base. The height of the bracket is controlled by a telescopic electric cylinder, and a limiting plate for limiting the drive axle is provided on the bracket.

[0006] Furthermore, the support base is slidable on the base, and the base is provided with a slide rail that cooperates with the sliding of the support base.

[0007] Furthermore, the limiting mechanism also includes a rotating arm, which is mounted on the mounting body via a rotating shaft, and the limiting rod is located at the end of the rotating arm.

[0008] The telescopic adjustment method of the limit rod includes rotary adjustment of the telescopic length or direct drive. The direct drive method refers to controlling its telescopic length through the telescopic mechanism of an electric cylinder, pneumatic cylinder or hydraulic cylinder.

[0009] Furthermore, a sliding component is provided on the side of the support base, which is used to realize the up and down sliding of the bracket.

[0010] The telescopic electric cylinder is either fixedly mounted on a support base or slidably mounted on a base.

[0011] The bracket is used to support the drive axle. The limiting plate on the bracket can rotate and is fixed by rotating it to fit against both sides of the drive axle.

[0012] Furthermore, the support frame and limiting mechanism are fixedly or slidably mounted on the support base.

[0013] Beneficial effects: Compared with the prior art, this utility model can control the two ends of the drive axle to be at the same horizontal height through the downward limiting rod, and can provide downward clamping force. The bracket and support frame can ensure that the axle housing of the drive axle remains stable during the processing. Attached Figure Description

[0015] Figure 2 This is a partial structural schematic diagram of the device described in this utility model;

[0016] Figure 3 This is a schematic diagram of the fixing of the drive axle according to this utility model. Detailed Implementation

[0017] To illustrate the technical solution provided by this utility model in detail, further description is provided below with reference to the accompanying drawings.

[0018] Combination Figures 1-3 As shown, the present invention provides a fixture for machining the hub mounting holes at both ends of an electric forklift drive axle. This fixture can be mounted on the base of a CNC machine tool via a base 1. Existing CNC machine tool machining typically involves placing the workpiece on the base of the CNC machine tool and then operating it via turrets at both ends. However, this presents an obstacle for the drive axle structure of electric forklifts, mainly because the middle section of the drive axle housing is larger than the two ends. Machining in the middle section is done from the side, including drilling (bolt holes), and... Figure 3 It can also be seen that the middle part has an asymmetrical structure, similar to a hemisphere. If the two ends are simply fixed, it is easy for it to deflect and cannot be fixed. Therefore, the bracket 5 described in this utility model is needed to provide stable support.

[0019] Furthermore, the fixture described in this utility model has support seats 2 at both ends on the horizontal platform surface of the base 1. The support seats 2 can be fixed with bolts, and after fixing, they can be used for processing drive axles of the same specification and model. For different models, the support seats 2 can be slidably set on the platform surface of the base 1. Figure 1The slide rail is shown. A support frame 4 is provided on the support base 2. The support frame 4 is used to support both ends of the drive axle housing. It is configured as a V-shape. A limit mechanism 3 is provided on one side of the support frame 4. The limit mechanism 3 includes a mounting body, which is fixed on the support base 2. A rotating shaft 302 is provided on the top of the mounting body. A rotating arm 303 is connected through the rotating shaft 302. A limit rod 301 is provided at the end of the rotating arm 303.

[0020] The limiting rod 301 includes a downward protrusion that can be achieved by rotation, allowing for downward telescopic adjustment. It also includes a mechanism that incorporates a telescopic electric cylinder, pneumatic cylinder, or hydraulic cylinder, controlling the downward extension of the telescopic rod via electric, pneumatic, or hydraulic means to abut against the upper part of the drive axle. It should be noted that the limiting mechanisms 3 are designed to be on the same horizontal line, and the initial position of the limiting rod 301 is also on the same horizontal line. In the limiting mechanisms 3 located at both ends of the base 1, the downward extension length of the limiting rod 301 is consistent, thus controlling the upper limit height of the drive axle. Its lower part is supported by the support frame 4 or bracket 5. The limiting rod 301 includes a scale, which facilitates ensuring consistent downward extension length. When one side of the drive axle does not abut against the lower part of the limiting rod 301, it can be adjusted upwards by adjusting the support frame 4 or bracket 5.

[0021] Combination Figure 2 As shown, the bottom of the bracket 5 is equipped with a telescopic electric cylinder 7, which is used to control the up and down adjustment of the bracket 5. The bracket 5 can be "L" shaped, and one side of it is set on the support base 2 through a sliding component 6. The sliding component 6 includes a slider fixed to one side of the bracket 5, and also includes a slide rail fixed to the side wall of the support base 2.

[0022] The bracket 5 has limit plates 8 at both ends for clamping the drive axle from the front and rear sides as shown in the figure. The limit plates 8 can be automatically adjusted or manually rotated to both sides of the drive axle and fixed by tightening bolts. The middle part of the bracket 5 can be extended, and may include two sets, located on both sides respectively. Figure 1-3 Only one side is shown.

[0023] Based on the above structure, this invention can be used to provide a rubber layer at the contact point with the drive axle, and also includes providing vertical height adjustment and horizontal sliding adjustment for the support base 2 based on the above structure. Furthermore, this invention also includes a floating and sliding configuration for the limiting mechanism 3 and the support frame 4 on the support base 2, meaning the floating support frame can slide on the support base 2.
