Description

Technical Field

[0001] This utility model belongs to the field of auxiliary equipment for mechanical processing, and in particular relates to a split bearing housing drilling and positioning fixture. Background Technology

[0002] In machining, especially for drilling of split bearing housings, traditional positioning methods often suffer from inaccurate positioning and inconvenient tooling adjustments. Currently, positioning of split bearing housings typically relies on manual operation, which can lead to deviations during machining and affect product quality. Furthermore, if different sizes of bearing housings require changing positioning blocks and adjusting multiple sets of bolts, installation efficiency is low.

[0003] Based on this, this utility model designs a split bearing housing drilling and positioning fixture to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a split bearing housing drilling and positioning fixture to solve the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] The split bearing housing drilling and positioning fixture includes a base and a clamping assembly. The clamping mechanism includes a T-shaped pressure plate, which consists of a connecting plate and a pressure plate. The pressure plate is located on the mounting hole of the split bearing housing. A positioning post is fixed to the bottom of the end of the connecting plate. A hollow tube is fixed on the base. The inner diameter of the hollow tube is larger than the outer diameter of the positioning post. The hollow tube and the positioning post are rotatably connected. An adjusting screw is vertically installed on the base. A through hole is opened in the center of the connecting plate. The adjusting screw passes through the through hole and through the T-shaped pressure plate. An adjusting nut is threaded on the adjusting screw and is located above the T-shaped pressure plate.

[0007] A compression spring is installed on the lower end face of the positioning post.

[0008] The base has symmetrical positioning grooves on both the left and right ends. The bottom surface of the positioning groove is arc-shaped to fit the outer arc surface of the connecting lug of the split bearing housing.

[0009] Several fixing blocks are fixed on the base, and threaded sleeves are horizontally installed on the fixing blocks. The threaded sleeves are connected to fine-tuning bolts, and the bolt heads of the fine-tuning bolts abut against the end face of the connecting lugs of the split bearing housing.

[0010] The diameter of the bolt head of the fine-tuning bolt is larger than the connecting hole on the connecting lug of the split bearing housing.

[0011] The head of the fine-tuning bolt has an anti-slip pad attached.

[0012] A welded nut is fixed on the base, and the adjusting screw is threadedly connected to the welded nut.

[0013] The base is fixed to the machine tool by several fixing bolts.

[0014] This utility model has the following beneficial effects:

[0015] The arc-shaped positioning groove matches the outer arc surface of the connecting lug of the split bearing housing, preventing bearing housing wobbling caused by vibration during drilling and improving drilling accuracy. The fine-adjustment bolt and anti-slip pad design prevent lateral slippage of the bearing housing, ensuring stable processing. The compression spring reduces effort when changing the bearing housing, decreasing the workload for operators. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. It should be understood that the terms "upper", "middle", "outer", "inner", "lower" etc., which indicate orientation or positional relationship, are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0023] The attached figures illustrate specific embodiments of this utility model, such as... Figures 1-3As shown, this utility model is a split-type bearing housing drilling and positioning fixture, including a base and a clamping assembly. The base 1 is fixed to a machine tool by several fixing bolts 12. (See reference for split-type bearing housing.) Figure 1 The base 1 has symmetrical positioning grooves 11 on both the left and right ends. The bottom surface of the positioning groove 11 is arc-shaped to fit the outer arc surface of the connecting lug of the split bearing housing.

[0024] The clamping mechanism includes a T-shaped pressure plate, which comprises a connecting plate 4 and a pressure plate 41. The pressure plate 41 is located on the mounting hole of the split bearing housing. A positioning post 43 is fixed to the bottom of the end of the connecting plate 4. A hollow tube 5 is fixed on the base 1. The inner diameter of the hollow tube 5 is larger than the outer diameter of the positioning post 43. The hollow tube 5 is rotatably connected to the positioning post 43. A welding nut 31 is fixed on the base 1. An adjusting screw 3 is threadedly connected to the welding nut 31. The adjusting screw 3 is installed vertically. A through hole 42 is opened in the center of the connecting plate 4. The adjusting screw 3 passes through the through hole 42 and penetrates the T-shaped pressure plate. The adjusting nut 32 is threaded on the adjusting screw 3 and is located above the T-shaped pressure plate.

[0025] At least two fixing blocks 2 are fixed on the base 1, located diagonally on the split bearing housing. Threaded sleeves 21 are horizontally mounted on the fixing blocks 2. The threaded sleeves 21 are threadedly connected to adjusting bolts 22. The bolt head diameter of the adjusting bolt 22 is larger than the connecting hole on the connecting lug of the split bearing housing, which increases the contact area with the split bearing housing. Anti-slip pads are attached to the bolt head of the adjusting bolt 22. Figure 1 When in use, the anti-slip pad abuts against the end face of the connecting lug of the split bearing housing.

[0026] In use, after assembling the two halves of the split bearing housing to be processed, place them on the base 1, ensuring that the outer arc surface of the bearing housing connecting lugs fits against the arc-shaped bottom surface of the positioning grooves 11 on both sides of the base 1. If there is left or right wobbling, rotate the fine-adjusting bolt 22 to press the anti-slip pad against the split bearing housing, thus fixing the split bearing housing. The anti-slip pad increases contact friction and prevents the bearing housing from sliding laterally during drilling. After adjusting the position of the bearing housing, use the clamping mechanism to fix it. First, press the pressure plate 41 onto the diameter of the bearing housing mounting hole, then rotate the adjusting nut 32 to fix the pressure plate 41. When replacing the balance shaft housing, loosen the adjusting nut 32, rotate the T-shaped pressure plate to one side through the hollow tube and positioning post 43, and after loosening the adjusting nut 32, the compression spring 44 returns to its original position, making it easier to remove the T-shaped pressure plate, thus saving effort.

[0027] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to specific implementation methods.
