The chuck is provided with an inclined surface. A limiting groove is provided on the limiting block. The sliding clamping block is slidably connected in the limiting block.

[0004] Although the above technical solutions have solved the corresponding technical problems, they still have the following drawbacks:

[0005] The bearing housing fixture described above uses a fixed plate and two chucks to clamp the bearing housing. During the clamping process, the contact area with the bearing housing is small, which leads to unstable clamping of the bearing housing and affects subsequent processing. Utility Model Content

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a bearing housing inner wall grinding fixture, including a base and a frame fixedly connected to the top of the base. A clamping and fixing mechanism for clamping and fixing the bearing housing to be processed is installed on the frame. The clamping and fixing mechanism includes an electric cylinder fixedly connected to the center of the top of the frame. A lifting seat is fixedly connected to the output end of the electric cylinder. First fixing components for clamping the bearing housing to be processed are installed on both sides of the bottom of the lifting seat. A second fixing component for clamping the bearing housing to be processed is installed between the two first fixing components. Two symmetrically arranged limiting and telescopic components are installed on the top of the second fixing component.

[0008] Furthermore, the first fixing component includes fixing pressure rods fixedly connected to both sides of the bottom of the lifting seat, and a fixing pressure plate is fixedly connected to the bottom of the fixing pressure rods.

[0011] Furthermore, an anti-slip pressure pad is fixedly connected to the bottom of the arc-shaped fixing plate.

[0012] Furthermore, the limiting telescopic assembly includes a telescopic sleeve fixedly connected to the bottom of the lifting seat, a connecting spring fixedly connected to the top of the inner wall of the telescopic sleeve, a sliding rod fixedly connected to the bottom of the connecting spring, and the other end of the sliding rod fixedly connected to the second fixing assembly.

[0013] Furthermore, a limit block is also fixedly connected to the slide rod.

[0027] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0029] like Figures 1-5 As shown, a bearing housing inner wall grinding fixture includes: a base 1 and a frame 2 fixedly connected to the top of the base 1. A clamping and fixing mechanism 3 for clamping and fixing the bearing housing to be processed is installed on the frame 2. The clamping and fixing mechanism 3 includes an electric cylinder 3011 fixedly connected to the center of the top of the frame 2. A lifting seat 301 is fixedly connected to the output end of the electric cylinder 3011. First fixing components 302 for clamping the bearing housing to be processed are installed on both sides of the bottom of the lifting seat 301. A second fixing component 303 for clamping the bearing housing to be processed is installed between the two first fixing components 302. Two symmetrically arranged limiting telescopic components 304 are installed on the top of the second fixing component 303.

[0030] By setting the limiting telescopic component 304, the bearing housing can be pressed and fixed from the arc-shaped position of the bearing housing. Moreover, by setting the two first fixing components 302, the bearing housing can be pressed and fixed from the two mounting holes of the bearing housing, thereby maximizing the stability of the bearing housing clamping and thus ensuring the stability of the subsequent processing of the bearing housing.

[0031] The first fixing component 302 includes fixing pressure rods 3021 fixedly connected to both sides of the bottom of the lifting base 301. A fixing pressure plate 3022 is fixedly connected to the bottom of each fixing pressure rod 3021. By setting the fixing pressure rods 3021 and the fixing pressure plate 3022, the bearing seat can be pressed and fixed at the mounting hole position. A fixing insert 3023 is fixedly connected to the bottom of the fixing pressure plate 3022. The fixing insert 3023 can be inserted into the mounting hole of the bearing seat, thereby increasing the stability of the bearing seat fixation. The second fixing component 303 includes an arc-shaped fixing plate 3031. Both sides of the arc-shaped fixing plate 3031 are fixedly connected to mounting sleeves 3032, and the mounting sleeves 3032 are slidably installed on the fixing pressure rod 3021. By setting the arc-shaped fixing plate 3031, the arc-shaped surface of the bearing seat can be pressed and fixed. The bottom of the arc-shaped fixing plate 3031 is fixedly connected to an anti-slip pressure pad 3033. By setting the anti-slip pressure pad 3033, the stability of pressing the bearing seat is increased, and damage to the bearing seat is avoided during pressing.

[0032] The limiting telescopic assembly 304 includes a telescopic sleeve 3041 fixedly connected to the bottom of the lifting base 301. A connecting spring 3042 is fixedly connected to the top of the inner wall of the telescopic sleeve 3041, and a sliding rod 3043 is fixedly connected to the bottom of the connecting spring 3042. The other end of the sliding rod 3043 is fixedly connected to the second fixing assembly 303. By setting the telescopic sleeve 3041 and the sliding rod 3043, the arc-shaped fixing plate 3031 is limited, thereby increasing the stability of the arc-shaped fixing plate 3031 in pressing and fixing the bearing seat. A limiting block 3044 is also fixedly connected to the sliding rod 3043. By setting the limiting block 3044, the sliding rod 3043 is limited, preventing the sliding rod 3043 from detaching from the telescopic sleeve 3041 during sliding. Two positioning blocks 101 are also set on the base 1. By setting the positioning blocks 101, the bearing seat is limited, thereby increasing the stability of the bearing seat placed on the base 1.

[0033] The working principle of this utility model is as follows: First, the bearing seat to be processed is placed on the base 1, and the two mounting holes of the bearing seat are aligned with the two positioning blocks 101. Then, the lifting seat 301 is driven to move down by the electric cylinder 3011. While the lifting seat 301 is moving down, the arc-shaped fixing plate 3031 first presses and fixes the arc-shaped surface of the bearing seat. Then, as the lifting seat 301 continues to move down, the sliding rod 3043 compresses the connecting spring 3042, and at the same time, the fixing block 3023 at the bottom of the fixing pressure plate 3022 is inserted into the mounting hole of the bearing seat, thereby realizing convenient and stable positioning of the bearing seat, thus increasing the stability of the subsequent processing of the bearing seat.

[0034] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
