Description

An adaptor clamping device for a hydraulic steering gear

Technical Field

The utility model relates to a clamping device, in particular to an adapting clamping device for a hydraulic steering gear.

Background Art

Hydraulic steering gear is a hydraulic power steering gear. The steering gear is a set of gear mechanisms that complete the conversion from rotary motion to linear motion. It is also a reduction transmission device in the steering system. One end of the hydraulic steering gear is cylindrical and the other end is rectangular. Since the two ends of the hydraulic steering gear are in different shapes, when the traditional clamp clamps the hydraulic steering gear, it is easy to be unstable and needs to be clamped with a special clamping device.

For example, a Chinese patent disclosed in the publication number CN219258834U discloses an adaptor clamping device for a hydraulic steering gear, comprising a fixed mounting plate, a first clamping arm, a second clamping arm, a clamping wheel, a first hydraulic rod, a second hydraulic rod and a plane clamping block, a group of first clamping arms and a group of second clamping arms are symmetrically installed on both sides of the fixed mounting plate, two groups of first sliding grooves are provided on both sides of the fixed mounting plate, the first clamping arm is slidably connected to the first sliding groove, the fixed mounting plate is installed with a first hydraulic rod, the output end of the first hydraulic rod is driven to connect to the first clamping arm, the second clamping arm is slidably connected to the first sliding groove, the end of the fixed mounting plate is fixedly installed with a second hydraulic rod, the output end of the second hydraulic rod is driven to connect to the second clamping arm, the first clamping arm is installed with a clamping wheel, and a plane clamping block is fixedly installed on the side of the second clamping arm near one end. In the utility model, the clamping of hydraulic steering gears of various specifications is realized by independently controlling the clamping arms of different clamping end faces through four hydraulic rods.

Some problems were found when using the above-mentioned existing adapter clamping device for the hydraulic steering gear. First, a hydraulic rod is used to push the clamping arm to clamp the hydraulic steering gear. It is difficult for the hydraulic rod to control the clamping force. Excessive force may cause damage to the surface coating or shell of the hydraulic steering gear. If the clamping force is too small, it is difficult to stably clamp the hydraulic steering gear.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-3. The utility model provides a technical solution: an adapter clamping device for a hydraulic steering gear, including a fixed mounting plate 1, a clamping wheel 4, and a plane supporting block 5. T-shaped slide grooves 101 are symmetrically opened on both sides of the fixed mounting plate 1. A T-shaped slider 201 is slidably installed in the T-shaped slide groove 101. A clamping arm 2 is fixedly installed on one side of the T-shaped slider 201. A second slide groove 203 is opened in the clamping arm 2. A connecting slider 3 is arranged in the second slide groove 203. A connecting slide hole 301 is opened in the connecting slider 3. A connecting rod 302 is fixedly installed on the clamping wheel 4 and the plane supporting block 5. The connecting rod 302 is slidably matched with the connecting slide hole 301. A threaded groove is opened on the outer wall of the connecting rod 302. An adjusting nut 6 is threadedly installed on the threaded groove. A return spring 601 is sleeved on the connecting rod 302.

In this embodiment, by adjusting the spacing between the clamping arms 2 symmetrically arranged on both sides, the movement of the clamping arms 2 can drive the movement of the connecting slider 3. The movement of the connecting slider 3 will drive the clamping wheel 4 and the plane supporting block 5 to move respectively through the connecting rod 302, thereby clamping the hydraulic steering gear through the clamping wheel 4 and the plane supporting block 5. When the clamping wheel 4 and the plane supporting block 5 are close to clamping the hydraulic steering gear, after the clamping wheel 4 and the plane supporting block 5 are in contact with the surface of the hydraulic steering gear, the clamping arms 2 continue to approach each other. At this time, the clamping wheel 4 and the plane supporting block 5 will stop moving, and the connecting rod 302 will slide inside the connecting slide hole 301. At the same time, the return spring 601 will be compressed. At this time, the return spring 601 will provide a certain thrust to the clamping wheel 4 and the plane supporting block 5. The thrust provided at this time is the clamping force of the clamping wheel 4 and the plane supporting block 5. Rotating the adjusting nut 6 can squeeze or release the return spring 601, thereby adjusting the thrust of the return spring 601, so as to facilitate adjusting the clamping force according to actual conditions.

Among them, in order to achieve the purpose of adjusting the distance between the clamping arms 2, the present device adopts the following technical solution: a threaded shaft 102 is rotatably installed in the T-shaped slide groove 101, a motor 103 is fixedly installed on the front of the fixed mounting plate 1, the motor 103 is fixedly connected to the threaded shaft 102, and a threaded through hole 202 is opened in the T-shaped slider 201, and the threaded through hole 202 is threadedly matched with the threaded shaft 102.

By starting the motor 103, the threaded shaft 102 can be driven to rotate. The threaded shaft 102 is threadedly matched with the threaded through hole 202, so that the rotation of the threaded shaft 102 can drive two symmetrically arranged T-shaped sliders 201 on one side to move closer to or away from each other, and the movement of the T-shaped slider 201 will drive the clamping arm 2 to move.

Among them, in order to achieve the purpose of limiting the clamping wheel 4 and the plane supporting block 5 to move only forward and backward, the present device adopts the following technical solutions: a limiting block 303 is fixedly installed at the other end of the connecting rod 302, a limiting sliding hole 304 is opened near a corner in the connecting slider 3, and a limiting rod 305 is fixedly installed on the clamping wheel 4 and the plane supporting block 5, and the limiting rod 305 is slidably matched with the limiting sliding hole 304.

The limit block 303 prevents the connecting rod 302 from sliding out of the connecting slide hole 301. The limit slide hole 304 is set at the corner. In order to avoid interference between the limit rod 305 and the connecting rod 302, the limit slide hole 304 and the limit rod 305 slide together to limit the clamping wheel 4 and the plane supporting block 5 to move forward and backward, thereby preventing the clamping wheel 4 and the plane supporting block 5 from rotating.

The working principle and use process of the utility model: when using, the device needs to be placed in a suitable position, and the motor 103 is started to drive the threaded shaft 102 to rotate. The rotation of the threaded shaft 102 can drive the two sets of clamping arms 2 on both sides to approach each other. The movement of the clamping arms 2 can drive the clamping wheel 4 and the plane supporting block 5 to approach each other. After the clamping wheel 4 and the plane supporting block 5 are attached to the surface of the hydraulic steering gear, the clamping arms 2 continue to approach each other. At this time, the clamping wheel 4 and the plane supporting block 5 will stop moving, and the connecting rod 302 will slide inside the connecting slide hole 301. At the same time, the return spring 601 will be compressed. At this time, the return spring 601 will provide a certain thrust to the clamping wheel 4 and the plane supporting block 5. The thrust provided at this time is the clamping force of the clamping wheel 4 and the plane supporting block 5. Rotating the adjusting nut 6 can squeeze or release the return spring 601, thereby adjusting the thrust of the adjusting nut 6.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
