Abstract
The invention relates to a floating protective pressing machine. A pump body is arranged at the upper part of a limiting seat, a machine body is arranged above the pump body and is provided with a screw, a thread bushing is arranged at part of the machine body outside the screw, a swinging pressing head is suspended at the front end of the screw in a floating manner, a big end hole of the pump body is vertically upward and coaxial with the screw, a pump cover is arranged on a spring in the big end hole of the pump body, the upper part of the screw is provided with a hand wheel set, and a steel cable baffle ring is arranged in a locating ring slot in the side surface of an inner hole of the pump body. The floating protective pressing machine provided by the invention can achieve the purposes that the pressing head floats to be centered and aligned and no relative motion between the pressing head and the contact surface of the pump cover is caused in a pump cover pressing process, so that the effects that the pump cover is moved down smoothly and is difficultly blocked in a pressing process and the surface of the pump cover is not scratched can be guaranteed, defective rate is reduced, cost is lowered, reworking frequency is reduced, and working efficiency is improved.
Description
Technical field
The present invention relates to machine-building and press-fit the field, relate in particular to a kind of erection unit of power assistance pump for steering pump cover.
Background technology
At present, generally adopt common spiral to press down that mode realizes in the assembly technology to power steering hydraulic pump pump cover (and elastic spring), be that rotation hand wheel descends the screw rod rotation, thereby directly push the pump cover Compress Spring, pump cover is moved down along the large end endoporus of the pump housing, after exposing the positioning ring groove at the large end of the pump housing place elastic spring is installed, is counter-rotated again handwheel and make and move the location on the pump cover.The method that this kind directly pushes very easily scratches pump cover, and percent defective is high, and is very easily stuck in the large end of the pump housing when pump cover moves down because the perpendicularity deviation of screw rod and workpiece pump cover is larger, thereby causes doing over again and the damage of seal, and the Efficiency Decreasing cost is improved.
Summary of the invention
In order to overcome the easily easy problem such as scuffing in stuck, protection pump cover surface of existing hydraulic pump pump cover assembling process pump cover, the invention provides a kind of unsteady protection type pressing machine.
The technical scheme that the present invention adopts for achieving the above object is: the protection type pressing machine floats, the pump housing is installed on limit base top, body is installed in pump housing top, screw rod is installed on the body, be positioned at the outside thread bush of installing of screw rod on the body, swing pressure head and float and hang on screw front end, the large stomidium of the pump housing straight up and and screw coaxial, pump cover is installed on the interior spring of the large stomidium of the pump housing, and the handwheel group is installed on screw rod top.
Elastic spring is installed in the positioning ring groove of described pump housing endoporus side.
Unsteady protection type pressing machine of the present invention, realization press-fits in the pump cover process, pressure head float centrih centering, with the pump cover contact-making surface without relatively moving, thereby guarantee to press-fit the process pump cover move down smooth and easy be difficult for stuck, pump cover is surperficial does not scratch, reduce the defective products rate, reduce cost, reduce the number of times of doing over again, improved operating efficiency.
Description of drawings
Fig. 1 is unsteady protection type pressing machine left view of the present invention.
Among the figure: handwheel group 1, thread bush 2, body 3, screw rod 4 swings pressure head 5, elastic spring 6 pump covers 7, spring 8, the pump housing 9, limit base 10.
The specific embodiment
Unsteady protection type pressing machine structure of the present invention as shown in Figure 1, mainly by pressing machine, pump cover 7, the pump housing 9, spring 8, elastic spring 6, limit base 10 realize, pressing machine comprises: handwheel group 1, thread bush 2, body 3, screw rod 4 swings pressure head 5.The pump housing 9 is installed on limit base 10 tops, body 3 is installed in the pump housing 9 tops, screw rod 4 is installed on the body 3, be positioned at the screw rod 4 outside thread bush 2 of installing on the body 3, swing pressure head 5 unsteady screw rod 4 front ends that hang on, the pump housing 9 large stomidiums straight up and coaxial with screw rod 4, pump cover 7 is installed on the spring 8 in the pump housing 9 large stomidiums, handwheel group 1 is installed on screw rod 4 tops.Elastic spring 6 is installed in the positioning ring groove of the pump housing 9 endoporus sides.
During use, will swing pressure head 5 first, revolve screw rod 4 bulb end screw threads fully, floating hangs on screw rod 4 front ends; Again the pump housing 9 is placed on the limit base 10, guarantee the pump housing 9 large stomidiums straight up and coaxial with screw rod 4, pump cover 7 is put on the spring 8 in the pump housing 9 large stomidiums; Then rotate that handwheel group 1 drives screw rod 4 to swing pressure heads 5 along thread bush 2 guiding by hand and rotation moves down, after swing pressure head 5 touches pump cover 7, according to pump cover 7 planes along screw rod 4 bulb automatic capturings, the simultaneously effect owing to frictional force stops operating (become screw rod 4 bulbs and swing relatively rotating of pressure head 5) and only moves down, thereby pump cover 7 Compress Springs 8 are moved down along the pump housing 9 large end endoporus, expose the positioning ring groove of endoporus side elastic spring 6 is installed again, last reversing handle group 1 makes to move on the pump cover 7 and is positioned elastic spring 6.Move down along pump housing endoporus and smooth and easyly be difficult for stuck, protection pump cover surface and be not scratched thereby guarantee to press-fit the process pump cover, reduce the defective products rate, reduce cost, reduce the number of times of doing over again, improved operating efficiency.
