Abstract

The invention provides a multifunctional clamp for a strip-shaped bearing. The multifunctional clamp comprises a spindle (1) and a clamp (2), wherein one end of the spindle (1) is fixedly provided with the clamp (2), and the other end of the spindle (1) is fixedly provided with a hydraulic cylinder (3); a push rod (11) is inserted and sleeved at the center of the spindle (1); and one end of the push rod (11) is fixedly connected to a push-forward rod of the hydraulic cylinder (3), and the other end of the push rod (11) is pressed on a center lug (21) of the clamp (2). The structure of the clamp (2) is as follows: the center lug (21) is formed at the center of one side of a connection plate (22), and the center of the other side of the connection plate (22) is fixedly provided with an ejector rod (23) and a plurality of clamping blocks (24) arranged in a circle around the ejector rod (23); and a pressing rod device (4) is fixedly arranged on each clamping block (24). The multifunctional clamp for the strip-shaped bearing can be used for clamping the strip-shaped bearings to be machined with different but approximate diameters, so as to overcome the defects in the prior art.

Description

A kind of anchor clamps of multi-functional strip bearing

Technical field:

The present invention relates to the grinding machine equipment technical field, more specifically to a kind of anchor clamps of multi-functional strip bearing.

Background technology:

The anchor clamps of existing strip bearing outer ring grinding machine generally are corresponding one by one with the need machining bearing; Just the unilateral bearing that is fit to this bearing is installed to the bearing of this kind of clamping need processing on the main shaft of grinding machine according to a kind of diameter of machining bearing, when the diameter of machining bearing more close but not simultaneously, appoint the unilateral bearing that so needs to prepare various correspondences; It bothers very much; And to prepare various unilateral bearing, its cost is high, changes and management inconvenience.

Summary of the invention:

The object of the invention is exactly the deficiency to prior art, and a kind of anchor clamps of multi-functional strip bearing are provided, and it can process the strip bearing by the different but close need of clamping diameter, has solved the deficiency of prior art.

Technological solution of the present invention is following:

A kind of anchor clamps of multi-functional strip bearing; Comprise main shaft and anchor clamps; Main shaft one end is fixed with anchor clamps, the other end is fixed with hydraulic cylinder, and the alignment of shafts is inserted with push rod, and push rod one end is fixed on the catch bar of hydraulic cylinder, the other end is pressed against on the center projection of anchor clamps;

Said clamp structure does, terminal pad one side center forms the center projection, and terminal pad opposite side center fixation has push rod a plurality ofly to be arranged in round fixture block around push rod with forming, and is fixed with strut device on the fixture block.

Said center projection is a cylindrical bump, and push rod is screwed onto on the terminal pad.

Whenever on the fixture block of a fixture block, be fixed with strut device, said strut device is screwed onto on the fixture block for the adjustment bolt, and adjusting nut is screwed onto on the adjustment bolt, and adjusting nut is pressed against on the fixture block lateral wall.

Beneficial effect of the present invention is:

It promotes push rod through the catch bar of hydraulic cylinder; Push rod is pressed against on the center projection of anchor clamps; Make a plurality of fixture blocks outwards part a little, can satisfy the close strip bearing sleeve to be processed of diameter like this and be clamped between the fixture block, and be pressed against the bottom of strip bearing to be processed through push rod; Be pressed against on the bearing to be processed through the rotation adjusting bolt then, come the fastening adjustment bolt to be pressed against on the bearing to be processed through regulating adjusting nut.

Description of drawings:

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the structural representation of anchor clamps;

Fig. 3 is the A-A cutaway view of Fig. 1;

Among the figure: 1, main shaft; 11, push rod; 2, anchor clamps; 21, center projection; 22, terminal pad; 23, push rod; 24, fixture block; 3, hydraulic cylinder; 4, strut device; 41, adjustment bolt; 42, adjusting nut.

The specific embodiment:

Embodiment: see the anchor clamps of Fig. 1 to a kind of multi-functional strip bearing shown in Figure 3; Comprise main shaft 1 and anchor clamps 2; Main shaft 1 one ends are fixed with anchor clamps 2, the other end is fixed with hydraulic cylinder 3; Main shaft 1 center is inserted with push rod 11, and push rod 11 1 ends are fixed on the catch bar of hydraulic cylinder 3, the other end is pressed against on the center projection 21 of anchor clamps 2;

Said anchor clamps 2 structures do, terminal pad 22 1 side centers form center projection 21, and terminal pad 22 opposite side center fixation have push rod 23 a plurality ofly to be arranged in round fixture block 24 around push rod 23 with forming, and are fixed with strut device 4 on the fixture block 24.

Said center projection 21 is a cylindrical bump, and push rod 23 is screwed onto on the terminal pad 22.

Whenever on the fixture block 24 of a fixture block 24, be fixed with strut device 4, said strut device 4 is screwed onto on the fixture block 24 for adjustment bolt 41, and adjusting nut 42 is screwed onto on the adjustment bolt 41, and adjusting nut 42 is pressed against on fixture block 24 lateral walls.

Operation principle: the catch bar through hydraulic cylinder 3 promotes push rod 11, and push rod 11 is pressed against on the center projection 21 of anchor clamps, makes a plurality of fixture blocks 24 outwards part a little; Strip bearing sleeve to be processed is between fixture block 24; Push rod 23 is pressed against the bottom center of strip bearing to be processed, and push rod 11 is return then, and anchor clamps 2 recover original state like this; In the middle of fixture block 24 is clamped in strip bearing to be processed; Be pressed against on the bearing to be processed through rotation adjusting bolt 41, come fastening adjustment bolt 41 to be pressed against on the bearing to be processed, accomplish clamping bearing to be processed through regulating adjusting nut 42.
