Technical Field

The utility model belongs to the technical field of bearing pressure testing, in particular to a testing machine for bearing pressure testing.

Background Art

Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies and reduce the friction coefficient during their movement. After the bearings are processed, they need to be placed on top of a pressure testing machine for pressure testing to determine the bearing's pressure-bearing performance.

When the existing bearing pressure test machine is used to pressure test the bearing parts, when the bearing is placed on the top of the test machine, the bearing will roll on the top of the test machine, causing misalignment between the bearing and the hydraulic column, resulting in the hydraulic column being unable to accurately press on the top of the bearing to pressure test the bearing. Therefore, improvement is needed.

Utility Model Content

In order to overcome the above defects, the utility model provides a testing machine for bearing pressure testing, which solves the problem that when the bearing is placed on the top of the testing machine, the bearing will roll on the top of the testing machine, affecting the pressure applied to the bearing for pressure testing.

To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a test machine for bearing pressure testing, comprising a base frame, a mounting plate fixedly mounted on the top of the base frame, rectangular grooves symmetrically arranged on both sides of the top of the mounting plate, and an adjusting screw rotatably mounted inside the rectangular groove, a limit slide bar fixedly mounted at the bottom of the adjusting screw inside the rectangular groove, and moving blocks symmetrically arranged on the surfaces of both ends of two sets of limit slide bars and the adjusting screw located inside the rectangular groove;

A card block is fixedly installed on the top of the moving block, and a controller is provided on one side of the top of the mounting plate. A clamping mechanism is symmetrically provided on both sides of the top of the mounting plate, located at the two groups of card blocks. Two groups of support columns are symmetrically fixedly installed at the central positions on both sides of the mounting plate, and a top plate is fixedly installed on the top of the four groups of support columns. A hydraulic column is fixedly installed at the central position of the top of the top plate, and the bottom end of the hydraulic column passes through the bottom of the top plate and corresponds to the central position between the two groups of card blocks.

As a further solution of the utility model: the threads on the surfaces at both ends of the adjusting screw are in opposite directions, and both ends of the adjusting screw pass through two groups of rectangular grooves and extend to the outside of the mounting plate.

As a further solution of the utility model: locking studs are fixedly installed at both ends of the adjusting screw located outside the mounting plate, and a cross plate is fixedly installed at one end of the locking stud, and a locking screw sleeve is provided on the surface of the locking stud.

As a further solution of the utility model: the clamping mechanism includes a fixing plate, two groups of clamping rods are symmetrically and slidably installed on one side of the fixing plate, and one end of the two groups of clamping rods passes through the fixing plate and is fixedly installed with a limiting connecting plate.

As a further solution of the utility model: a clamping block is fixedly installed on one end of the clamping rod away from the limiting connecting plate, and a clamping spring is provided on the surface of the clamping rod located between the fixing plate and the clamping block.

As a further solution of the utility model: one side of the clamping block is semi-arc-shaped, and the arc surface of the clamping block is provided with anti-slip grooves.

Compared with the prior art, the beneficial effects of the present invention are:

1. The bearing pressure test test machine is provided with a rectangular slot, an adjusting screw, a limit slide bar, a moving block and a clamping block. The adjusting screw is controlled to rotate forward or reverse according to the size of the bearing, and the moving blocks on both sides of the adjusting screw are controlled to move in opposite directions on the surfaces of the limit slide bar and the adjusting screw, driving the two groups of clamping blocks to move away from or close to each other until the two groups of clamping blocks can be tightly attached to the surface of the outer ring of the bearing when the bearing is vertically placed on the top of the mounting plate, ensuring that the bearing will not roll to both sides when pressurized for pressure testing, and will not be misaligned with the hydraulic column, affecting the pressure test of the bearing.

2. The bearing pressure test machine is provided with a fixing plate, a clamping rod, a clamping block and a clamping spring. The clamping blocks are pushed to both sides to compress and deform the clamping springs between the fixing plate and the clamping blocks. After the bearing is placed between the two sets of clamping blocks, the two sets of clamping blocks are released and pushed toward the bearing under the rebound action of the clamping springs and clamped on both sides of the bearing, so as to facilitate the clamping and fixing of the bearing and ensure that the bearing will not tip over during the pressure test.

3. The bearing pressure test machine is provided with locking studs, cross plates and locking screw sleeves. The cross plates are held and rotated to drive the adjusting screw to rotate, thereby controlling the moving block to drive the clamping block to move. After the two sets of clamping blocks can be tightly attached to the outer ring of the bearing, the two sets of locking screw sleeves are tightened to lock and fix the locking studs and the adjusting screw to ensure that the adjusting screw does not rotate, causing the moving block to move, driving the clamping block away from the bearing, and causing the bearing to shake between the two sets of clamping blocks.

DETAILED DESCRIPTION

The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

As shown in Figures 1-3, the utility model provides a technical solution: a testing machine for bearing pressure testing, including a base frame 1, a mounting plate 2 is fixedly installed on the top of the base frame 1, rectangular grooves 201 are symmetrically provided on both sides of the top of the mounting plate 2, and an adjusting screw 202 is rotatably installed inside the rectangular groove 201, the threads on the surfaces of both ends of the adjusting screw 202 are in opposite directions, and the two ends of the adjusting screw 202 pass through the two groups of rectangular grooves 201 and extend to the outside of the mounting plate 2. Because the adjusting screw 202 is provided, the adjusting screw 202 is controlled to rotate, which facilitates the control of the two groups of moving blocks 204 on both sides of the adjusting screw 202 to move closer to or away from each other.

The adjusting screw 202 is located on the outer side of the mounting plate 2 at both ends thereof and is fixedly mounted with locking studs 206, and one end of the locking stud 206 is fixedly mounted with a cross plate 207, and a locking screw sleeve 208 is provided on the surface of the locking stud 206. By providing the locking screw sleeve 208, the locking screw sleeve 208 is tightened to lock and fix the locking stud 206, thereby ensuring that the adjusting screw 202 will not rotate after the moving block 204 moves to the specified position.

A limiting slide bar 203 is fixedly installed at the bottom of the adjusting screw 202 inside the rectangular groove 201, and moving blocks 204 are symmetrically arranged on the surfaces of both ends of the two sets of limiting slide bars 203 and the adjusting screw 202 located inside the rectangular groove 201. Due to the limiting slide bar 203, when the moving block 204 moves due to the rotation of the adjusting screw 202, the moving block 204 is prevented from rotating synchronously with the adjusting screw 202, causing the block 205 to deflect;

A clamping block 205 is fixedly installed on the top of the moving block 204. One side of the clamping block 205 is semi-arc-shaped, and the arc surface of the clamping block 205 is provided with anti-slip grooves 209. Because of the anti-slip grooves 209, when the clamping block 205 is close to the outer ring of the bearing, the outer ring of the bearing contacts with the anti-slip grooves 209, increasing the friction between the clamping block 205 and preventing the bearing from rotating between the two groups of clamping blocks 205.

A controller 3 is provided on one side of the top of the mounting plate 2, and a clamping mechanism 4 is symmetrically provided on both sides of the two groups of clamping blocks 205 on the top of the mounting plate 2. The clamping mechanism 4 includes a fixed plate 401, and two groups of clamping rods 402 are symmetrically and slidably installed on one side of the fixed plate 401, and one end of the two groups of clamping rods 402 pass through the fixed plate 401 and are fixedly installed with a limited connecting plate 403. By providing the limited connecting plate 403, it is ensured that when the clamping block 404 is pushed to move, the two groups of clamping rods 402 can move synchronously, so that the clamping block 404 moves smoothly.

A clamping block 404 is fixedly installed at one end of the clamping rod 402 away from the limiting connecting plate 403, and a clamping spring 405 is provided on the surface of the clamping rod 402 located between the fixed plate 401 and the clamping block 404. Due to the provision of the clamping spring 405, the clamping block 404 is clamped on both sides of the bearing under the rebound action of the clamping spring 405, which facilitates the clamping and fixing of the bearing.

Two groups of support columns 5 are symmetrically fixedly installed at the central positions on both sides of the mounting plate 2, and a top plate 6 is fixedly installed on the top of the four groups of support columns 5. A hydraulic column 7 is fixedly installed at the central position of the top of the top plate 6, and the bottom end of the hydraulic column 7 passes through the bottom of the top plate 6 and corresponds to the central position between the two groups of blocks 205. By providing the hydraulic column 7, after the bearing is fixed between the two groups of blocks 205, the hydraulic column 7 is controlled to press the bearing downward to ensure that the center position of the bottom of the hydraulic column 7 is pressed tightly against the top of the bearing, exerting pressure on the bearing to make the bearing evenly stressed.

The working principle of the utility model is:

According to the size of the bearing, two sets of cross plates 207 are held and rotated to control the synchronous rotation of the adjusting screw 202, so that the two sets of moving blocks 204 on the surface of the adjusting screw 202 are close to or away from each other, until the bearing is placed on the top of the mounting plate 2, and the two sets of clamping blocks 205 can be close to the outer ring of the bearing to ensure that the central position of the top of the bearing corresponds to the central position of the bottom of the hydraulic column 7, and the two sets of locking screw sleeves 208 are tightened to lock the adjusting screw 202, and the two sets of clamping blocks 404 are pushed to both sides. After the bearing is placed between the two sets of clamping blocks 404, the clamping blocks 404 are loosened and pushed against the bearing under the elastic action of the clamping spring 405 to clamp the bearing, and the hydraulic column 7 is controlled to rise and fall to apply pressure to the bearing for pressure testing.
