Description

Technical Field

[0001] The utility model relates to the technical field of vehicle parts processing, in particular to a tool for processing a front spring left bracket. Background Art

[0002] The left front spring bracket is an important component of heavy trucks. It is used to connect the leaf spring and the chassis. When the vehicle encounters large bumps during driving, the bump force generated by the wheel is transmitted to the chassis through the leaf spring, which greatly alleviates the impact of the vehicle bumps on the chassis and plays a role in protecting the components installed on the chassis.

[0003] The left front spring bracket needs to be milled and drilled during processing. After the workpiece is clamped and fixed with a fixture, the left front spring bracket is milled and drilled using equipment such as a milling machine and a drilling machine. The existing left front spring bracket tooling generally clamps and fixes the workpiece from the left and right sides. Since the left front spring bracket has an irregular structure, the clamping is not firm and the left front spring bracket is prone to offset during processing, which affects the accuracy of the workpiece, causes a high failure rate of the workpiece, and wastes raw materials. Utility Model Content

[0004] The utility model aims to solve the problem that the left bracket of the front spring is not firmly clamped during machining, which affects the machining accuracy. The utility model provides a front spring left bracket milling tool that can firmly clamp the left bracket of the front spring and is not prone to deviation during milling surface drilling.

[0005] In order to solve the above technical problems, the utility model includes a base plate and a clamping member for fixing and clamping the left bracket of the front spring, and its structural features are: the base plate is provided with a fixed support plate for supporting the first connecting plate of the left bracket of the front spring, the support plate is provided with a first limiting component for limiting the mounting hole column on the first connecting plate, the clamping member includes at least one pressure plate for pressing the first connecting plate, the base plate is provided with a first protrusion for supporting the left bracket of the front spring and several support members of the mounting plate, and the base plate is also provided with a second limiting component for limiting the mounting plate.

[0006] After adopting the above structure, the support plate supports the first connecting plate of the front spring left bracket, the support member supports the first protrusion and the mounting plate of the front spring left bracket, and the pressure plate presses the first connecting plate to fix and clamp the front spring left bracket. Under the action of the support plate, the support member and the pressure plate, the front spring left bracket is firmly clamped; the first limiting assembly and the second limiting assembly limit the mounting hole column and the mounting plate respectively, to prevent position deviation during the milling and drilling of the front spring left bracket, thereby improving the processing accuracy.

[0007] Furthermore, the first limiting assembly includes at least two first limiting members for limiting the mounting hole column from different directions.

[0008] Furthermore, the first limiting member is a first bolt, the first bolt is screwed on the vertical plate, and the vertical plate is fixedly connected to the support plate.

[0009] Furthermore, the pressure plate is located above the first connecting plate, and the pressure plate presses the first connecting plate through a clamping bolt, and the clamping bolt passes through the weight-reducing holes of the pressure plate and the first connecting plate and is screwed to the support plate.

[0010] Furthermore, the support member is a bolt screwed onto the base plate.

[0011] Furthermore, one end of the support plate is in contact with the second connecting plate of the front spring left bracket.

[0012] Furthermore, the second limiting assembly includes a second bolt resting against the side of the mounting plate, the second bolt is threadedly connected to the bolt fixing block, the bolt fixing block is fixed on the positioning plate, and the positioning plate is fixed on the bottom plate.

[0013] Furthermore, the bottom plate is provided with a plurality of assembly holes for fixing the tooling.

[0014] The utility model firmly clamps and stably supports the front spring left bracket through the support plate, the pressure plate and the support member. The first limit assembly and the second limit assembly limit two different parts of the front spring left bracket, which can prevent the front spring left bracket from shifting during milling and drilling processing, thereby improving the processing accuracy and qualified rate. The front spring left bracket milling tooling of the utility model has the characteristics of firm clamping and the workpiece position is not easy to shift during milling and drilling processing.

The base plate 1 is provided with a plurality of assembly holes 10 for tooling installation and fixation.

[0024] Instructions for use: Install the column 3, support plate 2 (support plate 2 is welded to the upper end of the column 3), the third bolt 7, the positioning plate 803 (the positioning plate 803 is installed with a bolt fixing block 802), the fourth bolt 9, etc. on the base plate 1, fix the first vertical plate 402 (the first vertical plate 402 and the second vertical plate 403 are welded into one) to the support plate 2, screw the third bolt 7 and the fourth bolt 9 to the base plate 1, screw the first bolt 401 to the first vertical plate 402 and the second vertical plate 403, and screw the second bolt 801 to the bolt fixing block 802. After the above components are installed and fixed, install the base plate 1 on the processing equipment. Place the left front spring bracket 11 on the processing tooling so that the first connecting plate 1101 of the left front spring bracket 11 falls on the support plate 2, the side of the second connecting plate 1102 is attached to the right side of the support plate 2, and the mounting hole column 1103 is located in the frame formed by the first vertical plate 402 and the second vertical plate 403.
