Description

Technical Field

[0001] This invention relates to the field of machining, and in particular to a bearing housing positioning mechanism. Background Technology

[0002] See Figure 1 This is a schematic diagram of a bearing housing structure. This bearing housing has a rectangular block structure with thickness, with one end as a connecting end and the other end as a bearing assembly end. The width of the connecting end is smaller than the width of the bearing assembly end. A connecting base plate is welded to the connecting end of the bearing housing, extending along the width direction of the bearing housing, with its two extended ends exceeding the sides containing the length and thickness of the bearing assembly end, respectively. A bearing hole extending through the bearing along the thickness direction is provided on the bearing assembly end for assembling the bearing.

[0003] When machining companies mill the side where the bearing assembly end is located (length and thickness), the extension end of the connecting base plate exceeds the limit. If the bearing housing is directly clamped on the milling machine table, the side where the bearing assembly end is located (length and thickness) will extend at an angle, making normal milling impossible.

[0004] Therefore, how to design a dedicated positioning mechanism to meet the requirements of milling the bearing housing bearing assembly end corresponding side is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a bearing housing positioning mechanism. This mechanism has a simple structure, low processing cost, and can quickly, efficiently, and stably position the bearing housing while ensuring that the side of the bearing housing where the bearing assembly end is located is horizontal, thus meeting the requirements of milling.

[0006] The technical solution of this invention is: a bearing housing positioning mechanism, comprising a positioning base with an L-shaped cross-section, a centering seat, a pull rod, a limiting block, a pressure seat, and a top seat. The centering seat includes a positioning disc assembled in the bearing hole of the bearing housing, the diameter of which is adapted to the inner diameter of the bearing hole. The pressure seat includes a pressure rod and two connecting rods. The top seat includes a seat body and a support bolt threaded onto the top of the seat body. The horizontal plane of the positioning base is fixedly mounted on a milling machine table. One end of the pull rod is fixed to the vertical plane of the positioning base, and the other end extends horizontally, passing through the circle of the positioning disc. The bearing seat is pressed against the vertical surface of the positioning base by a center and a limiting block, and is centered. The seat body of the top base is supported on the milling machine table, and the nuts of the supporting bolts provide support to the bottom side of the bearing seat connection end where the length and thickness are located, so that the bearing assembly end of the bearing seat is horizontal. Two connecting rods are fixed on the milling machine table on both sides of the bearing seat. The extended ends of the two connecting rods pass through the pressure rod and are respectively threaded with locking nuts, so that the pressure rod is pressed against the top side of the bearing seat connection end where the length and thickness are located, thus positioning the bearing seat.

[0007] One or more reinforcing blocks are connected between the vertical back side and the horizontal top side of the positioning base.

[0008] The limiting block is provided with a strip-shaped hole extending along the length direction, and the other end of the pull rod passes through the strip-shaped hole of the limiting block and is threadedly engaged with the locking nut.

[0009] The pull rod is a screw rod, and one end of the pull rod is threaded into the vertical surface of the positioning base to form a fixed position. The positioning plate is installed on the pull rod through a threaded connection.

[0010] The base has a frustum structure, and two clamping planes are symmetrically arranged on the upper circumference of the frustum structure base.

[0011] The extension line of the support bolt passes through the pressure bar.

[0012] The above technical solution has the following beneficial effects: 1. The bearing housing positioning mechanism includes an L-shaped positioning base, a centering seat, a tie rod, a limiting block, a pressure seat, and a top seat. Through the cooperation of these components, the bearing housing is positioned, ensuring that the length and thickness of the bearing housing's bearing assembly end extend horizontally. The centering seat includes a positioning disc fitted into the bearing hole of the bearing housing. The diameter of the positioning disc is adapted to the inner diameter of the bearing hole, meaning the positioning disc transitions into the bearing hole and is concentrically positioned with it. The pressure seat includes a pressure rod and two connecting rods, applying a downward force to the bearing housing. The top seat includes a seat body and a support bolt threaded onto the top of the seat body, applying an upward force to the bearing housing. The horizontal plane of the positioning base is fixedly mounted on the milling machine table, and its position on the milling machine table can be adjusted as needed. One end of the pull rod is fixed to the vertical surface of the positioning base, and the other end extends horizontally, passing through the center of the positioning plate and the limiting block, and is threaded with a locking nut to press the bearing seat firmly onto the vertical surface of the positioning base and center it. That is, the bearing seat to be milled mates with the positioning plate through the bearing hole, so that the side of the bearing seat containing the length and width is in contact with the vertical surface of the positioning base and remains vertical. The base body of the top seat is supported on the milling machine table, and the nut of the support bolt provides support to the bottom side of the bearing seat connecting end containing the length and thickness, so that the side of the bearing seat containing the length and thickness of the bearing assembly end is horizontal. That is, the height of the connecting end of the bearing seat can be controlled by adjusting the thread fit length of the support bolt to meet the positioning requirements of bearing seats of various specifications. Two connecting rods are fixed on the milling machine table, located on both sides of the bearing seat. The extended ends of the two connecting rods pass through the pressure rod and are threaded with locking nuts, so that the pressure rod is pressed against the top side of the bearing seat where the length and thickness of the connecting end are located, thus positioning the bearing seat. The positioning structure is simple, the positioning operation is convenient, and the positioning state is stable, meeting the needs of milling.

[0013] 2. The limiting block is provided with a strip hole extending along the length direction. The other end of the pull rod passes through the strip hole of the limiting block and engages with the locking nut threadedly, so that the position of the limiting block can be adjusted through the strip hole to meet the actual use requirements.

[0014] 3. The pull rod is a screw rod. One end of the pull rod is threaded into the vertical surface of the positioning base to form a fixed position. The positioning plate is installed on the pull rod through a threaded engagement. The threaded engagement between the positioning plate and the pull rod facilitates the adjustment of the distance between the positioning plate and the vertical surface of the positioning base, meeting actual usage requirements and ensuring the stability of the positioning plate relative to the pull rod, thereby ensuring the stability of the bearing seat positioning.

[0015] 4. The base has a frustum structure. The upper part of the frustum structure has two symmetrical clamping planes, which make it convenient for operators to clamp the base with tools and thus facilitate the adjustment of the thread fit length of the support bolts.

[0016] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details. Attached Figure Description

The pressure seat 5 includes a pressure rod 51 and two connecting rods 52. Typically, the pressure rod is a rectangular tube. The top seat 6 includes a seat body 61 and a support bolt 62 threaded to the top of the seat body 61. In this embodiment, the seat body 61 has a frustum structure, and two clamping planes 63 are symmetrically arranged on the upper circumference of the frustum structure seat body 61. The horizontal surface 11 of the positioning base 1 is fixedly installed on the milling machine table. One end of the pull rod 3 is fixed on the vertical surface 12 of the positioning base 1, and the other end extends horizontally, passing through the center of the positioning plate 21 and the limiting block 4, and is threadedly engaged with the locking nut 22 to press the bearing seat tightly onto the vertical surface 12 of the positioning base and center it. Obviously, the milling machine table is provided with multiple parallel T-slots. The horizontal surface of the positioning base is fixed to the milling machine table by multiple conventional side-top clamps. In order to strengthen the positioning base... To enhance the structural strength of the base, one or more reinforcing blocks 13 are connected between the back side of the vertical surface 12 and the top side of the horizontal surface 11 of the positioning base 1. In this embodiment, the limiting block 4 is provided with a strip-shaped hole 41 extending along the length direction. The pull rod 3 is a screw rod, and one end of the pull rod 3 is threadedly engaged with the vertical surface 12 of the positioning base to form a fixed connection. The positioning plate 21 is installed on the pull rod through a threaded engagement, which facilitates the adjustment of the distance between the positioning plate and the vertical surface of the positioning base, meets the actual use requirements, and ensures the stability of the positioning plate relative to the pull rod. The base body 61 of the top seat 6 is supported on the milling machine table, and the nuts of the supporting bolts 62 provide support to the bottom side where the length and thickness of the bearing seat connection end are located, making the side where the bearing assembly end of the bearing seat is located horizontal. Two connecting rods 52 are fixed on the milling machine table, located on both sides of the bearing seat. The extended ends of the two connecting rods 52 pass through the pressure rod 51 and are respectively threaded with locking nuts 53, so that the pressure rod 51 presses against the top side of the bearing seat where the length and thickness of the connecting end are located, thus positioning the bearing seat. In order to improve the stability of the positioning, the extension line of the support bolt 62 passes through the pressure rod 51.
