Background
For press fitting of the elastic part, the existing press fitting method is to press the elastic part into the workpiece hole by clamping with a clamp, but the press fitting method usually damages the elastic part and can not play the due function of the elastic part when being embedded in the workpiece hole.
SUMMERY OF THE UTILITY MODEL
In view of this, the main object of the present invention is to provide a feeding press-fitting mechanism, which can press the elastic member into the workpiece hole without damage.
The utility model relates to a work piece upper end is arranged in to material loading pressure equipment mechanism, it includes:
a pressure head 3 which reciprocates up and down,
the material loading guide sleeve 4 is sleeved on the pressure head 3, the pressure head 3 can extend out or retract from the lower end of the material loading guide sleeve 4, and the lower end of the pressure head 3 in the material loading guide sleeve 4 is a material loading position.
From above, when the pressure head moves downwards and extends out of the feeding guide sleeve 4, the elastic part arranged at the feeding position is pressed into the workpiece hole at the lower part in an undamaged way, and the press mounting of the elastic part is completed.
Preferably, the pressure head 3 is a cylindrical body, the outer side wall of which is provided with at least two opposite strip-shaped grooves 32 parallel to the axial direction along the circumferential direction,
the side wall of the feeding guide sleeve 4 is provided with a through hole corresponding to the groove 32,
the limiting nail penetrates through the through hole from the outer side of the feeding guide sleeve (4) and extends into the groove 32.
The feeding guide sleeve is limited by the upper limit nail and the elongated groove on the pressure head, the limit nail extends into the groove and cannot slide down, and the pressure head can move up and down relative to the feeding guide sleeve within the length range of the groove.
Preferably, a step 31 is arranged on the pressing head 3, the upper end of the feeding guide sleeve 4 is located at the lower part of the step 31, and a spring is arranged between the step 31 and the upper end surface of the feeding guide sleeve 4.
When the pressure head moves downwards, the feeding guide sleeve and the pressure head move downwards together due to the existence of the limit nail, and the feeding guide sleeve does not move downwards any more when contacting with the end surface of the workpiece hole at the lower part, and is always pressed on the end surface of the workpiece hole due to the existence of the spring; however, the pressure head continuously extends downwards out of the feeding guide sleeve within the length range of the groove under the action of downward pressure, extends into the workpiece hole at the lower part, and presses the elastic part at the lower part into the workpiece hole.
Preferably, the stamping device further comprises a stamping part 1 which is arranged at the upper part of the pressure head 3 and is in threaded connection and locking through a locking nut 2.
From top to bottom, the stamping workpiece passes through lock nut and is connected together with the pressure head, presses the pressure head downstream when the stamping workpiece downstream. The stamping part can be arranged to be very long, the diameter is large, the stamping part can bear the pressure applied to the stamping part by the air cylinder, the diameters of the pressing heads are the same due to the fact that the diameters of the elastic parts needing press mounting are different, the pressing heads and the stamping part are arranged separately, and the pressing heads can be replaced conveniently when different elastic parts are press mounted.
Preferably, the stamping part 1 is driven by an air cylinder to reciprocate up and down.

FIG. 1 is a schematic three-dimensional structure diagram of a feeding press-fitting mechanism;
FIG. 2 is a front view of a feeding press-fit mechanism;
FIG. 3 is a cross-sectional view taken along line A-A of FIG. 2;
fig. 4 is a schematic structural diagram of the indenter.
Detailed Description
As shown in fig. 1, 2 and 3, the feeding press-fitting mechanism includes a stamping part 1 driven by an air cylinder to reciprocate up and down, a press head 3 disposed at the lower end of the stamping part 1 and contacting with the stamping part, a lock nut 2 connecting the stamping part 1 and the press head 3, a feeding guide sleeve 4 sleeved outside the press head 3, and a spring disposed between the press head 3 and the feeding guide sleeve 4).
As shown in fig. 3 and 4, the stamping part 1 is a long cylinder with a larger diameter, the upper end of the stamping part is connected with the cylinder actuating part, the locking nut 2 is a guide sleeve with internal threads and openings at two sides, and the lower end of the stamping part 1 is connected and locked by the locking nut 2 through threads after being vertically matched and contacted with the upper end of the pressing head 3; the pressure head 3 is connected with the stamping part 1, and the lower end of the pressure head is contacted with the elastic body with relatively small diameter, so the diameter of the upper end of the pressure head is larger than that of the lower end of the pressure head, the joint of the upper end and the lower end of the pressure head 3 is provided with a step 31, the spring is arranged between the step 31 and the upper end surface of the feeding guide sleeve 4, the feeding guide sleeve 4 is sleeved on the outer side of the lower end of the pressure head 3, and; in order to prevent the feeding guide sleeve 4 from slipping from the lower part of the pressure head 3, two opposite strip-shaped grooves 32 are arranged on the small-diameter circumference below the step 31 of the pressure head 3 along the length direction of the pressure head, two opposite through holes are arranged on the circumference of the feeding guide sleeve 4, two limit nails respectively penetrate through the through holes on the feeding guide sleeve 4 from the outer side of the feeding guide sleeve 4, one end of each limit nail extending into the feeding guide sleeve 4 is arranged in each groove 32, so that the feeding guide sleeve cannot slip from the lower end of the pressure head due to the limit nails, the feeding guide sleeve and the pressure head cannot be twisted relatively, when the feeding guide sleeve is fixed, the pressure head can extend out from the lower end of the feeding guide sleeve under the action of downward pressure, and the extending distance is limited by the length of the strip-shaped.
When the feeding press-loading mechanism works, the stamping part 1 moves downwards under the action of the cylinder, because the stamping part 1 and the pressing head 3 are fastened into a whole through the locking nut 2, the pressing head 3 descends together when the stamping part 1 descends, the limiting nail exists, the feeding guide sleeve 4 also descends, when the lower end of the feeding guide sleeve 4 is pressed on the end surface of the workpiece hole at the lower part of the feeding guide sleeve, the feeding guide sleeve 4 is blocked by the end surface of the workpiece hole, because of the existence of the spring, the feeding guide sleeve 4 is always pressed on the end surface of the workpiece hole, when the feeding guide sleeve 4 is not moved, the continuous downward pressure of the pressing head 3 enables the lower end of the pressing head to extend out from the lower end of the feeding guide sleeve 4 and then extend into the workpiece hole right opposite to the feeding guide sleeve, an elastic piece at the lower end (feeding position) of the pressing head 3 in the feeding guide sleeve 4 is pressed into the workpiece hole in advance, and the press-loading of.
Before the elastic part is pressed, the pressing head 3 is required to be debugged to be opposite to the center of the workpiece hole, so that the pressing head 3 can downwards enter the workpiece hole to press the elastic body in place, and the problem that the elastic body is deformed by clamping the elastic body by a clamping piece in a pressing mode cannot occur in the feeding pressing mechanism. In addition, the loading press-fitting mechanism only needs to be debugged once during installation, so that the pressure head is aligned with the center of the workpiece hole, and the loading press-fitting mechanism can be reused later without debugging.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
