Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic angle cylinders, and in particular relates to a parallel hydraulic angle cylinder. Background Art

[0002] The oil cylinder is a hydraulic cylinder. The hydraulic cylinder is a linear motion actuator whose output force is proportional to the effective area of ​​the piston and the pressure difference on both sides. Its function is to convert hydraulic energy into mechanical energy. The input of the hydraulic cylinder is the flow rate and pressure of the fluid, and the output is the linear motion speed and force. The piston of the hydraulic cylinder can complete linear reciprocating motion, and the output linear displacement is limited. The hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy of reciprocating linear motion. The hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. The buffer device and the exhaust device depend on the specific application, and other devices are indispensable.

[0003] When the clamping cylinder in the existing technology is installed and used on the equipment workbench, it is mostly fixed by tightening bolts, but the threaded hole has a certain gap. During long-term use, the installation position of the cylinder is prone to loosening and displacement, thereby affecting the accuracy of the clamping. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a parallel hydraulic angle cylinder to solve the problem that the installation position of the existing hydraulic cylinder is prone to loosening and deviation during long-term use, thereby affecting the accuracy of clamping.

[0005] To achieve the above objectives, the utility model adopts the following technical solution: a parallel hydraulic angle cylinder, comprising a parallel hydraulic angle cylinder, a mounting countersunk hole is provided on the parallel hydraulic angle cylinder, a quick-release fastener is adapted to be inserted in the mounting countersunk hole, the quick-release fastener comprises an internal threaded part, an elastic plate is provided at one end of the internal threaded part, a clamping joint is formed at the end of the elastic plate, an inner conical groove is formed on the inner wall of the elastic plate, a bolt is threadedly connected to the internal threaded part, a conical head is provided at the end of the bolt, and the elastic plate is adapted to be inserted in the through hole provided in the mounting plate.

[0006] The beneficial effects of the utility model are as follows: the parallel hydraulic angle cylinder can be installed and fixed quickly and stably by inserting the quick-install fasteners; the elastic plate can be deformed outwardly under the internal expansion support of the conical head to reduce the gap between it and the installation countersunk hole, thereby avoiding loosening and deviation of the installation position.

[0007] In order to effectively fix the position of the parallel hydraulic angle cylinder with quick-release fasteners;

[0008] As a further improvement of the above technical solution: the number of the elastic plates is three, and they are equidistantly arranged around the axis of the internal threaded part, the elastic plate is an arc plate structure, the clamping joint is a conical arc plate structure, and the bolt is a countersunk bolt structure.

[0009] The beneficial effect of this improvement is that the clamping joint can drive the elastic plate to produce elastic deformation after being squeezed by the inner wall of the mounting countersunk hole, and then be inserted into the mounting countersunk hole, and the parallel hydraulic angle cylinder can be firmly fixed on the mounting plate with the use of bolts.

[0010] In order to prevent the elastic plate from slipping in the mounting countersunk hole when the bolt is turned;

[0011] As a further improvement of the above technical solution: an anti-skid pad is arranged on the end surface of the clamping joint facing the elastic plate, the edge of the anti-skid pad does not exceed the edge of the clamping joint, and the surface of the anti-skid pad is provided with an anti-skid convex structure.

[0012] The beneficial effects of this improvement are: the anti-slip pad has a large surface friction coefficient, which can ensure a stable connection between the elastic plate and the mounting plate when the operator turns the bolt, thereby preventing the quick-release fastener from rotating and slipping in the mounting countersunk hole and the through hole opened on the mounting plate.

[0013] In order to make the card connector smoothly inserted into the parallel hydraulic angle cylinder and the mounting plate;

[0014] As a further improvement of the above technical solution: the outer diameter of the end of the clamping joint facing away from the elastic plate is not greater than the outer diameter of the internal threaded part, and the internal threaded part is clearance-fitted with the mounting countersunk hole and the through hole opened on the mounting plate.

[0015] The beneficial effect of this improvement is that the quick-release fastener can be smoothly inserted into the parallel hydraulic angle cylinder and the mounting plate as a whole.

[0016] In order to fully ensure the stability of the installation position of the parallel hydraulic angle cylinder on the mounting plate;

[0017] As a further improvement of the above technical solution: the conical head is a truncated cone structure which is wide at the top and narrow at the bottom, and the slope of the inclined surface of the conical head is the same as the slope of the inner conical groove.

[0018] The beneficial effect of this improvement is that when the conical head moves driven by the bolt, the elastic plate expands internally to reduce the gap between the elastic plate and the mounting countersunk hole, thereby preventing the mounting position from being easily loosened and offset.

[0019] In order to ensure the stability of the parallel hydraulic angle cylinder installed on the mounting plate;

[0020] As a further improvement of the above technical solution: the number of the mounting countersunk holes is multiple, and they are arranged at equal intervals around the axis of the push rod of the parallel hydraulic angle cylinder.

[0021] The beneficial effect of this improvement is that the quick-release fasteners inserted into the multiple mounting countersunk holes can stably connect the parallel hydraulic angle cylinder and the mounting plate.

[0022] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0029] Embodiment 1:

[0030] like Figure 1—4 shows: a parallel hydraulic angle cylinder, comprising a parallel hydraulic angle cylinder 1, the parallel hydraulic angle cylinder 1 is provided with a mounting countersunk hole 11, a quick-install fastener 3 is adapted to be inserted in the mounting countersunk hole 11, the quick-install fastener 3 comprises an internal threaded part 31, an elastic plate 32 is provided at one end of the internal threaded part 31, a clamping joint 33 is formed at the end of the elastic plate 32, an inner conical groove 34 is formed on the inner wall of the elastic plate 32, a bolt 36 is threadedly connected to the internal threaded part 31, a conical head 37 is provided at the end of the bolt 36, the elastic plate 32 is adapted to be inserted in the through hole provided in the mounting plate 2, and the parallelism is realized by inserting the quick-install fastener 3. The hydraulic angle cylinder 1 is installed and fixed quickly and stably; the elastic plate 32 can be deformed outwardly under the internal expansion support of the conical head 37 to reduce the gap between it and the mounting countersunk hole 11, thereby preventing the mounting position from being easily loosened and offset. The number of the elastic plates 32 is three, and they are arranged at equal intervals around the axis of the internal threaded member 31. The elastic plate 32 is an arc plate structure, the clamping joint 33 is a conical arc plate structure, and the bolt 36 is a countersunk bolt structure. After the clamping joint 33 is squeezed by the inner wall of the mounting countersunk hole 11, it can drive the elastic plate 32 to produce elastic deformation, and then be inserted into the mounting countersunk hole 11, and the parallel hydraulic angle cylinder 1 is firmly fixed with the use of the bolt 36. On the mounting plate 2, an anti-skid pad 35 is arranged on the end surface of one end of the clamping joint 33 facing the elastic plate 32, and the edge of the anti-skid pad 35 does not exceed the edge of the clamping joint 33. The surface of the anti-skid pad 35 is provided with an anti-skid convex structure. The surface friction coefficient of the anti-skid pad 35 is large, and the elastic plate 32 can be stably connected with the mounting plate 2 when the operator rotates the bolt 36, so as to prevent the quick-install fastener 3 from rotating and slipping in the mounting countersunk hole 11 and the through hole opened on the mounting plate 2. The outer diameter of the end of the clamping joint 33 facing away from the elastic plate 32 is not greater than the outer diameter of the internal threaded member 31, and the internal threaded member 31 is connected to the mounting countersunk hole 11 and the through hole opened on the mounting plate 2. The hole is a clearance fit, and the quick-release fastener 3 can be smoothly inserted into the parallel hydraulic angle cylinder 1 and the mounting plate 2 as a whole. The conical head 37 is a truncated cone structure that is wide at the top and narrow at the bottom. The inclination of the inclined surface of the conical head 37 is the same as the inclination of the inner conical groove 34. When the conical head 37 moves driven by the bolt 36, the elastic plate 32 is expanded and opened to reduce the gap between it and the mounting countersunk hole 11, thereby avoiding loosening and deviation of the mounting position. There are multiple mounting countersunk holes 11, and they are equidistantly spaced around the axis of the push rod of the parallel hydraulic angle cylinder 1. The quick-release fasteners 3 inserted in multiple mounting countersunk holes 11 can stably connect the parallel hydraulic angle cylinder 1 and the mounting plate 2.

[0031] The working principle of the present technical solution is as follows: when installing and fixing the parallel hydraulic angle cylinder 1, the quick-release fastener 3 is inserted as a whole into the mounting countersunk hole 11 and the mounting hole opened on the mounting plate 2. The clamping joint 33 is squeezed inward by the inner wall of the mounting countersunk hole 11 to produce elastic deformation. When the clamping joint 33 moves to the bottom of the mounting plate 2, the clamping joint 33 releases its elastic potential energy and is clamped on the lower side of the mounting plate 2. Then the operator uses a tool to tighten the bolt 36 to move the conical head 37 downward, thereby causing the conical head 37 to slide and push the inner conical groove 34 formed on the inner side of the elastic plate 32, thereby causing the elastic plate 32 to expand inward to reduce the gap between the mounting countersunk hole 11, and finally causing the head end of the bolt 36 to be pressed on the mounting countersunk hole 11.
