Description

Technical Field

[0001] The utility model relates to the technical field of locomotive maintenance equipment, and particularly to a disassembly fixture for a pneumatic locomotive speed sensor. Background Art

[0002] Traditional locomotive speed sensor disassembly tools are generally open-end wrenches, socket wrenches, sleeves, etc. These tools can be used to clamp or loosen the locomotive speed sensor, so as to disassemble the locomotive speed sensor. However, manually screwing the open-end wrench, socket wrench, and sleeve requires manual screwing. And a relatively large torque is required, so a large amount of manpower is needed for screwing, which is time-consuming and laborious. In order to improve efficiency.

[0003] In the prior art, a disassembly fixture is designed to be fixedly connected to a manipulator, and the manipulator provides torque to disassemble the pneumatic locomotive speed sensor. The pneumatic locomotive speed sensor to be disassembled is usually not a regular circle, and it is necessary to rotate and adjust the clamping position of the disassembly fixture.

[0004] However, in order to save costs, the manipulator usually adopts an industrial arm with relatively low rotation accuracy, and its rotation accuracy is limited. Each time it can only rotate a set angle value. For example, it can only rotate 10 degrees at a time, and the angle rotated each time is usually greater than or equal to 10 degrees. In this way, the manipulator cannot arbitrarily adjust the rotation angle of the disassembly fixture, which will cause the rotation adjustment of the clamping position of the disassembly fixture to be inconvenient, and ultimately may not be able to accurately rotate to the required clamping position.

[0005] That is to say, in the prior art, there is a problem that the rotation adjustment of the clamping position of the disassembly fixture is inconvenient. Summary of the Utility Model

[0006] The utility model provides a disassembly fixture for a pneumatic locomotive speed sensor, which is used to solve the problem that the rotation adjustment of the clamping position of the disassembly fixture is inconvenient.

[0007] The utility model provides a disassembly fixture for a pneumatic locomotive speed sensor, comprising:

[0008] An adapter plate; and

[0009] A quick-connect mechanism, which is arranged at one end of the adapter plate;

[0010] A clamping mechanism, which is arranged at the other end of the adapter plate, and the clamping mechanism is used to clamp the pneumatic locomotive speed sensor;

[0011] Among them, the quick-connect mechanism has a first rotating part and a second rotating part rotatably connected to the first rotating part. The second rotating part is connected to the manipulator, and the first rotating part is connected to the adapter plate. By adjusting the relative rotational position between the first rotating part and the second rotating part, the clamping position of the clamping mechanism is rotationally adjusted. When the manipulator drives the second rotating part to rotate, the second rotating part drives the first rotating part to rotate.

[0012] In one embodiment, a rotating hole is provided in the first rotating part, and the second rotating part is rotatably arranged in the rotating hole.

[0013] In one embodiment, the quick-connect mechanism further includes a locking member for fixing the relative rotational position between the first rotating part and the second rotating part, and the second rotating part drives the first rotating part to rotate through the locking member.

[0014] In one embodiment, a threaded through hole is provided on the outer periphery of the first rotating part, the locking member is a locking bolt, and the locking bolt is in threaded cooperation with the threaded through hole. By screwing the locking bolt, the second rotating part can be fixed in the rotating hole.

[0015] In one embodiment, the clamping mechanism includes:

[0016] A driving mechanism provided at the other end of the adapter plate; and

[0017] A first clamping arm connected to the driving mechanism; and

[0018] A second clamping arm connected to the driving mechanism;

[0019] Wherein, the first clamping arm and the second clamping arm are oppositely arranged in the first direction, and the driving mechanism can drive the first clamping arm and the second clamping arm to approach each other in the first direction to clamp the pneumatic locomotive speed sensor.

[0020] In one embodiment, the driving mechanism includes:

[0021] A first driving cylinder, whose fixed end is fixed at the other end of the adapter plate, and the driving end of the first driving cylinder is connected to the first clamping arm; and

[0022] A second driving cylinder, whose fixed end is fixed at the other end of the adapter plate, and the driving end of the second driving cylinder is connected to the second clamping arm;

[0023] Wherein, the first driving cylinder and the second driving cylinder are arranged in opposite directions in the first direction.

[0024] In one embodiment, the first driving cylinder and the second driving cylinder are single-acting double-rod cylinders or single-acting single-rod cylinders.

[0025] In one embodiment, the driving mechanism employs a double-acting double-rod cylinder. The fixed end of the double-acting double-rod cylinder is fixed to the other end of the adapter plate. The first telescopic end of the double-acting double-rod cylinder is connected to the first clamping arm, and the second telescopic end of the double-acting double-rod cylinder is connected to the second clamping arm.

[0026] In one embodiment, the first clamping arm includes:

[0027] A jaw, one end of which is connected to the other end of the adapter plate; and

[0028] An adapter block, which is arranged on the other end of the jaw. The adapter block is provided with a clamping opening for clamping the pneumatic locomotive speed sensor;

[0029] An insulating pad, which is arranged on the clamping opening.

[0030] Compared with the prior art, the advantages of the present utility model are that the quick-connecting mechanism is set as a split structure. Through the relative rotation of the second rotating part and the first rotating part, 360-degree rotation adjustment of the clamping mechanism can be realized. Furthermore, the clamping position of the disassembly fixture can be rotated and adjusted. In this way, the problem that the rotation adjustment of the clamping position of the disassembly fixture is inconvenient is avoided, thereby improving the clamping accuracy of the disassembly fixture. Furthermore, the clamping efficiency of the disassembly fixture is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The present utility model will be further described below in conjunction with the drawings.

[0041] Embodiment 1

[0042] As Figures 1 to 6 shown, the present utility model provides a disassembly fixture 100 for a pneumatic locomotive speed sensor. The disassembly fixture 100 includes an adapter plate 102, a quick-connection mechanism 101, and a clamping mechanism. Among them, the quick-connection mechanism 101 is disposed at one end of the adapter plate 102; the clamping mechanism is disposed at the other end of the adapter plate 102, and the clamping mechanism is used to clamp the pneumatic locomotive speed sensor; the quick-connection mechanism 101 has a first rotating part 1011 and a second rotating part 1012 rotatably connected to the first rotating part 1011. The second rotating part 1012 is connected to the manipulator, and the first rotating part 1011 is connected to the adapter plate 102. By adjusting the relative rotational position of the first rotating part 1011 and the first rotating part 1011, the clamping position of the clamping mechanism is rotationally adjusted.

[0043] In the above setting, the quick-connection mechanism 101 is set as a split structure. Through the relative rotation of the second rotating part 1012 and the first rotating part 1011, a 360-degree rotational adjustment of the clamping mechanism can be realized. Furthermore, the clamping position of the disassembly fixture 100 can be rotationally adjusted. This avoids the problem that the clamping position of the disassembly fixture is inconvenient to rotate and adjust, thereby improving the clamping accuracy of the disassembly fixture 100. Furthermore, the clamping efficiency of the disassembly fixture 100 is improved.

[0044] It should be noted that since the first rotating part 1011 and the second rotating part 1012 can rotate 360 degrees in a plane. This can realize a 360-degree adjustment of the pneumatic locomotive speed sensor. Thereby improving the clamping accuracy of the disassembly fixture 100. That is, the quick-connection mechanism 101 itself can adjust the clamping position of the disassembly fixture, and there is no need for the manipulator to adjust. The manipulator only needs to apply a rotational torque.

[0045] Specifically, as Figures 1 to 6 shown, in one embodiment, a rotation hole is provided in the first rotating part 1011, and the second rotating part 1012 is rotatably disposed in the rotation hole.

[0046] Specifically, as Figures 1 to 6As shown, in one embodiment, a rolling bearing may be provided between the rotating hole and the second rotating part 1012. This can improve the rotation efficiency between the first rotating part 1011 and the second rotating part 1012.

[0047] Specifically, as Figures 1 to 6 shown, in one embodiment, the quick-connect mechanism 101 further includes a locking member for fixing the relative rotational position of the first rotating part 1011 and the second rotating part 1012. This can ensure that when the manipulator transports the pneumatic locomotive speed sensor, the speed of the pneumatic locomotive does not wobble. Thus, it can avoid accidentally injuring on-site personnel and further improve the safety of its transportation.

[0048] Specifically, as Figures 1 to 6 shown, in one embodiment, a threaded through-hole is provided on the outer periphery of the first rotating part 1011. The locking member is a locking bolt that is threadedly engaged with the threaded through-hole. By screwing the locking bolt, the second rotating part 1012 can be fixed in the rotating hole.

[0049] It should be noted that for the locking method of the locking bolt, reference can be made to the locking method of the set screw. By screwing the locking bolt, one end of the locking bolt can be tightened against the second rotating part 1012.

[0050] Specifically, as Figures 1 to 6 shown, in one embodiment, a plurality of threaded through-holes are provided on the outer periphery of the first rotating part 1011, and a locking bolt is correspondingly provided for each threaded through-hole. By simultaneously tightening the plurality of locking bolts, the second rotating part 1012 can be fixed.

[0051] Specifically, as Figures 1 to 6 shown, in one embodiment, the clamping mechanism includes a driving mechanism 103, a first clamping arm, and a second clamping arm. Among them, the driving mechanism 103 is provided at the other end of the adapter plate 102; the first clamping arm is connected to the driving mechanism 103; the second clamping arm is connected to the driving mechanism 103; the first clamping arm and the second clamping arm are oppositely arranged in the first direction ( Figure 2 the horizontal direction), and the driving mechanism 103 can drive the first clamping arm and the second clamping arm to approach each other in the first direction to clamp the pneumatic locomotive speed sensor.

[0052] Specifically, as Figures 1 to 6As shown, in one embodiment, the driving mechanism 103 includes a first driving cylinder 1031 and a second driving cylinder 1032. Among them, for the first driving cylinder 1031, its fixed end is fixed on the other end of the adapter plate 102, and the driving end of the first driving cylinder 1031 is connected to the first clamping arm; for the second driving cylinder 1032, its fixed end is fixed on the other end of the adapter plate 102, and the driving end of the second driving cylinder 1032 is connected to the second clamping arm; the first driving cylinder 1031 and the second driving cylinder 1032 are arranged in opposite directions in the first direction.

[0053] In the above setting, both the first driving cylinder 1031 and the second driving cylinder 1032 are connected to an external air source, and the first driving cylinder 1031 and the second driving cylinder 1032 can drive the first clamping arm and the second clamping arm to approach or move away from each other. Thus, clamping or releasing of the pneumatic locomotive speed sensor is achieved.

[0054] Specifically, as Figures 1 to 6 shown, in one embodiment, the first driving cylinder 1031 and the second driving cylinder 1032 adopt single-acting double-rod cylinders. This can enhance the clamping force of the first and second clamping arms. Thus, the clamping force requirement for the pneumatic locomotive speed sensor is met.

[0055] It should be noted that the single-acting double-rod cylinder is a prior art, and its specific structure and working principle can be referred to in the Chinese invention patent: CN103410805B. Of course, a single-acting single-rod cylinder can be adopted according to actual situations.

[0056] Specifically, as Figures 1 to 6 shown, in one embodiment, the first clamping arm and the second clamping arm have the same structure. This enables the first clamping arm and the second clamping arm to be interchangeable, thereby improving the subsequent replacement of the disassembly fixture 100.

[0057] Specifically, as Figures 1 to 6 shown, in one embodiment, the first clamping arm includes a jaw 104, an adapter block 105, and an insulating pad 106. Among them, for the jaw 104, one end thereof is connected to the other end of the adapter plate 102; for the adapter block 105, it is arranged at the other end of the jaw 104, and the adapter block 105 is provided with a clamping opening for clamping the pneumatic locomotive speed sensor; for the insulating pad 106, it is arranged on the clamping opening.

[0058] It should be noted that the insulating pad 106 is usually made of a non-metallic material, which can prevent scratching the outer surface of the pneumatic locomotive speed sensor.

[0059] Specifically, as Figures 1 to 6 shown, in one embodiment, the shape of the clamping opening is a right-angle opening, and the outer shape of the insulating pad 106 is the same as that of an angle steel. This design can reduce the contact area with the pneumatic locomotive speed sensor. Further, it can prevent scratching the outer surface of the pneumatic locomotive speed sensor.

[0060] It should be noted that the disassembly angle in the first embodiment of this application has the following characteristics:

[0061] 1. Simple operation: The design of this disassembly fixture simplifies the operation steps, without the need to use too many tools or complex operation skills, reducing the operation time and possible errors.

[0062] 2. Stability: By using an open clamp cylinder (cylinder), it ensures the continuous and stable output of the clamping force during the disassembly process, reducing the possibility of damaging the locomotive speed sensor due to unstable clamping force.

[0063] 3. High efficiency: By connecting an air compression device, it provides strong power and efficiency, making the disassembly of the locomotive speed sensor easier and more efficient. The speed and efficiency of replacing and repairing the locomotive speed sensor are greatly improved, saving time and human resources.

[0064] In summary, this disassembly fixture has the advantages of simple operation, stability, high efficiency, etc., making the replacement and repair work of the locomotive speed sensor more convenient, fast and safe, and improving the repair efficiency and quality.

The first telescopic end of the double-acting double-rod cylinder is connected to the first clamping arm, and the second telescopic end of the double-acting double-rod cylinder is connected to the second clamping arm. This can reduce the volume of the driving mechanism and the number of driving cylinders. Thereby reducing the weight of the disassembly fixture and also saving costs.

[0068] It should be noted that the double-acting double-rod cylinder is a prior art, and its specific structure and working principle will not be elaborated here.

[0069] Specifically, in one embodiment, the shape of the clamping mouth is arc-shaped, and the insulating pad is an arc-shaped gasket.

[0070] The other structures of Embodiment 2 are the same as those of Embodiment 1 and will not be elaborated here.

[0071] It should be noted that the disassembly angle in the second embodiment of this application has the following characteristics:
