In the figure: the clamping device comprises a base (1), a clamping cylinder (2), a mounting hole (3), a supporting member (4), a first groove (41), a second groove (42), a screw (43), a supporting block (44), a limiting nut (45) and a compression spring (46).
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-4, a hydraulic component special fixture, including base 1, be provided with centre gripping cylinder 2 on the base 1, offer the mounting hole 3 that is used for fixed hydraulic component and distributes along 2 axis circumference of centre gripping cylinder on the base 1, a side that base 1 set up centre gripping cylinder 2 is provided with supporting member 4.
In this embodiment, the mounting holes 3 are threaded holes, and when a hydraulic component is mounted, counter bores can be processed in advance on the hydraulic component, the positions of the mounting holes 3 correspond to the positions of the counter bores one by one, and the hydraulic component is fixed to the base 1 through hexagon socket head cap screws.
In this embodiment, the supporting member 4 includes a groove opened on the base 1 and a supporting block 44 capable of rotating and protruding the groove; specifically, the grooves include a first rectangular groove 41 and a second rectangular groove 42 with a width smaller than that of the first rectangular groove 41, the support block 44 is connected in the second rectangular groove 42 in a lifting and rotating manner through an elastic limiting component, when a hydraulic component is installed, the support block 44 is stretched towards the outer side of the base 1, so that the bottom of the support block 44 is higher than the upper end face of the second rectangular groove 42, then the support block 44 is rotated by a certain angle, and the bottom of the support block 44 falls on the bottom face of the first rectangular groove 41; the upper end of the supporting block 44 is higher than the base 1, and supports the base 1 on the working platform together with the clamping cylinder 2, so as to prevent the base 1 from tilting.
In this embodiment, the supporting block 44 is a hollow structure, the elastic limiting component includes a screw 43 disposed at the bottom of the second groove 42 and penetrating into the cavity of the supporting block 44, a limiting nut 45 is disposed at the top of the screw 43, a compression spring 46 is disposed between the limiting nut 45 and the bottom of the supporting block 44, and the compression spring 46 is sleeved on the screw 43. When not using supporting member 4, place the supporting shoe 44 in the second recess 42, under compression spring 46's effort, supporting shoe 44 can not freely slide and rotate, avoids when processing hydraulic pressure part, and the first recess 41 of supporting shoe 44 roll-off has improved the utility model provides a security.
The hollow structure of the supporting block 44 reduces the overall weight of the utility model, which is convenient for taking and placing and also saves raw materials.
Preferably, the height of the supporting block 44 is equal to or greater than the sum of the depth of the first groove 41 and the height of the clamping cylinder 2. When the support block 44 is used to support the base 1, the support block 44 is always in contact with the work platform. Further, the two supporting members 4 are symmetrically arranged about the axis of the clamping cylinder 2, so that the supporting reliability is ensured.
