Problems solved by technology

[0002] The automobile steering pump is structurally composed of a pump body, a pulley, and an oil pot. The rotating shaft of the pump body and the center hole of the pulley are in an interference fit relationship. When assembling, it needs to be assembled by a press machine with a pressure of 5 tons. The pulley is set on the rotating shaft of the pump body. However, the pressing head on the market acts on the workpiece directly from top to bottom, and the pump body and the pulley cannot withstand the pressure due to their materials. Therefore, none of the press-fitting machines currently on the market are suitable, and it is necessary to develop press-fitting equipment dedicated to assembling the steering pump body and pulley.

Embodiment

[0013] Example: see figure 1 Shown:

[0014] A steering pump body pulley assembly equipment, see figure 1 As shown, it includes a worktable 1, on which a positioning tool 11 is fixed, on which the pulley 2 and the pump body 3 are placed sequentially from bottom to top. The positioning tool 11 positions the pulley 2 and the pump body 3, keeps the pulley 2 on the bottom, the pump body 3 (drawn by a dotted line in the figure) on the top, and the rotating shaft of the pump body 3 is opposite to the central hole of the pulley 2 The position state ensures that the pulley 2 cannot move downward relative to the worktable, while the pump body 3 can move downward relative to the worktable.

[0015] see figure 1 As shown, a pull-down device 4 is provided under the worktable 1 , and the pull-down device 4 includes a vertically moving seat 41 , a central rotating shaft 42 , a rotary drive device 43 , a tension sensor 44 and a vertical drive device 45 . The up and down moving seat 41 is...

Abstract

The invention provides steering pump body belt wheel assembling equipment. The steering pump body belt wheel assembling equipment is characterized by comprising a work table top (1), and a locating tool (11) is fixedly arranged on the work table top (1); a downward-pulling acting device (4) is arranged below the work table top (1) and comprises a vertical moving seat (41), a center rotary shaft (42), a rotary drive device (43), a tension sensor (44) and a vertical drive device (45); the axis of the center rotary shaft (42) coincides with the center axis of a belt wheel (2) on the locating tool (11); a screw (421) extends upwards from the top end of the center rotary shaft (42) and matched with a threaded hole in the end face of a rotary shaft of a pump body (3); the rotary drive device (43) drives the center rotary shaft (42) to rotate; and the vertical drive device (45) drives the vertical moving seat (41) to drive the center rotary shaft (42) to move downwards, so that the rotary shaft of the pump body (3) is pulled downwards, and the rotary shaft is embedded in a center hole of the belt wheel (2).

Description

technical field [0001] The invention relates to an automatic assembly device, in particular to an automatic press-fitting device specially used for assembling a steering pump body and a pulley. The device is used to complete the press-fitting step of inserting the rotating shaft of the pump body into the center hole of the pulley. Background technique [0002] The automobile steering pump is structurally composed of a pump body, a pulley, and an oil pot. The rotating shaft of the pump body and the center hole of the pulley are in an interference fit relationship. When assembling, it needs to be assembled by a press machine with a pressure of 5 tons. The pulley is set on the rotating shaft of the pump body. However, the pressing head on the market acts on the workpiece directly from top to bottom, and the pump body and the pulley cannot withstand the pressure due to their materials. Therefore, the press-fitting machines on the market are not applicable, and it is necessary to...
