Description

Technical Field

[0001] The utility model relates to the technical field of actuator accessories, in particular to a clamp structure of an actuator. Background Art

[0002] The actuator of the electronic speed governor is one of the components of the diesel engine control part. It is directly connected to the engine oil pump rack. The rationality of its structure is directly related to the performance of the entire control system, and the actuator's chuck structure is its output component.

[0003] After searching, the utility model with Chinese patent announcement number CN203239460U discloses an actuator of an engine electronic speed governor, including a housing, an electromagnetic induction mechanism, and a mechanical transmission mechanism. The electromagnetic induction mechanism and the mechanical transmission mechanism are fixedly connected through a main shaft. One end of the main shaft is fixed to the inner wall of the housing close to the electromagnetic induction mechanism, and the other end is connected to the mechanical transmission mechanism. The mechanical transmission mechanism includes a swing rod, a transmission rod, and a connecting head for connecting the swing rod and the main shaft. One end of the swing rod is tightly nested with the main shaft through the connecting head.

[0004] The connector of the above-mentioned chuck structure is directly nested outside the main shaft to achieve the connection purpose. The connector is an integrated design, so it does not have an avoidance gap and cannot adapt to the main shaft connection in different scenarios, making the adaptability of the device insufficient. Utility Model Content

[0005] The purpose of the utility model is to provide a clamping head structure of an actuator to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the chuck structure of the actuator includes a connecting seat, which is characterized in that: a fixing plate is fixedly connected to the bottom of the outer wall on one side of the connecting seat, and a clamping plate is fixedly connected to the top of the outer wall on one side of the connecting seat, and the outer walls of the fixing plate and the end of the clamping plate close to each other are both provided with spindle clamping holes, and the two spindle clamping holes are symmetrically arranged, and there is an avoidance gap between the fixing plate and the clamping plate, and a fixing screw is inserted in the clamping plate, and one end of the fixing screw can be threadedly connected to the fixing plate.

[0007] Because an avoidance space is set between the fixed plate and the clamping plate, the device can be used for spindle connection work in different scenarios in conjunction with the fastening screws, thereby improving the adaptability of the structure. The gap formed by the two spindle clamping holes is aligned with the external spindle, and is sleeved on the outside of the spindle. Then the fastening screw is turned. As one end of the fastening screw is gradually screwed into the fixed plate, the other end of the screw will drive the clamping plate to bend and move closer to the fixed plate, so that the fixed plate and the clamping plate can be tightly wrapped around the outer wall of the spindle.

[0008] As a further preferred embodiment of the present technical solution, a mounting plate is fixedly connected to the outer wall on the other side of the connecting seat, a bearing connecting rod is installed in the mounting plate, and two bearings are fixedly sleeved in the bearing connecting rod, which can improve the propulsion performance of the chuck and have a greater transmission effect.

[0009] As a further preferred embodiment of the present technical solution, a limit rod is threadedly connected to the connecting seat, and the limit rod can penetrate the connecting seat and extend downward, thereby providing a limit effect and limiting the range of motion.

[0010] As a further preferred embodiment of the present technical solution, the outer threaded sleeve of the limiting rod is provided with a reinforcing nut, and the reinforcing nut can contact the outer wall of the top of the connecting seat.

[0011] As a further preferred embodiment of the present technical solution, the circumferential inner walls of the two spindle clamping holes are both provided with thread grooves.

[0012] As a further preferred embodiment of the present technical solution, the inner diameter of the receiving hole in the clamping plate for receiving the fixing screw is larger than the outer diameter of the fixing screw.

[0013] The utility model provides a clamping head structure of an actuator, which has the following beneficial effects:

[0014] (1) The utility model provides a fixing plate, a clamping plate and a fixing screw. Since an avoidance space is provided between the fixing plate and the clamping plate, the fixing screw can be used for spindle connection work in different scenarios, thereby improving the adaptability of the structure. The gap formed by the two spindle clamping holes is aligned with the external spindle, and the clamping plate is sleeved on the outside of the spindle. Then, the fixing screw is rotated. As one end of the fixing screw is gradually screwed into the fixing plate, the other end of the fixing screw will drive the clamping plate to bend and move closer to the fixing plate, so that the fixing plate and the clamping plate can be tightly wrapped on the outer wall of the spindle.

[0015] (2) The utility model can improve the propulsion performance of the chuck by providing multiple sets of bearings, thereby achieving a greater transmission effect.

[0016] (3) The utility model can provide a limiting effect and restrict the range of motion by setting a limiting rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the chuck structure of the actuator includes a connecting seat 1, which is characterized in that: a fixing plate 2 is fixedly connected to the bottom of the outer wall on one side of the connecting seat 1, a clamping plate 3 is fixedly connected to the top of the outer wall on one side of the connecting seat 1, and a spindle clamping hole 4 is provided on the outer wall at one end of the fixing plate 2 and the clamping plate 3 that are close to each other, and the two spindle clamping holes 4 are symmetrically arranged, and there is an avoidance gap between the fixing plate 2 and the clamping plate 3, and a fastening screw 5 is inserted in the clamping plate 3, and one end of the fastening screw 5 can be threadedly connected in the fixing plate 2.

[0024] Align the gap formed by the two spindle clamping holes 4 with the external spindle, and sleeve it on the outside of the spindle, then turn the fixing screw 5. As one end of the fixing screw 5 gradually screws into the fixing plate 2, the other end of the fixing screw 5 will drive the clamping plate 3 to bend and move closer to the fixing plate 2, so that the fixing plate 2 and the clamping plate 3 can be tightly wrapped around the outer wall of the spindle.

[0025] like Figure 1 and Figure 2 As shown, the outer wall of the other side of the connecting seat 1 is fixedly connected with a mounting plate 6, a bearing connecting rod 7 is installed in the mounting plate 6, and two bearings 8 are fixedly sleeved in the bearing connecting rod 7, which can improve the propulsion performance of the chuck and have a greater transmission effect;

[0026] The preferred model of bearing 8 is (625ZZ1MC3ERMNS7S).

[0027] like Figure 2 and Figure 4 As shown, a limit rod 9 is threadedly connected in the connection seat 1. The limit rod 9 can penetrate the connection seat 1 and extend downward, so as to provide a limit effect and limit the range of motion.

[0028] The outer thread sleeve of the limiting rod 9 is provided with a reinforcing nut 10, and the reinforcing nut 10 can contact with the outer wall of the top of the connecting seat 1, and can further fix the position of the limiting rod 9 so that the position will not change arbitrarily due to the increase of use time.

[0029] like Figure 1 and Figure 3 As shown, the inner walls of the two main shaft clamping holes 4 are both provided with thread grooves 11 to increase the friction at the connection with the main shaft and avoid side slip.

[0030] like Figure 1 and Figure 2 As shown, the inner diameter of the receiving hole in the clamping plate 3 for receiving the fastening screw 5 is larger than the outer diameter of the fastening screw 5, so that when the clamping plate 3 approaches the external spindle, it will not be unable to move normally due to the limitation of the receiving hole.

[0031] The utility model provides a clamping head structure of an actuator, and the specific working principle is as follows:

[0032] When the device is working, first screw the limit rod 9 into the connecting seat 1, and make one end of it pass through the connecting seat 1 to play a limiting effect for the subsequent use process, then thread the reinforcing nut 10 on the outside of the limit rod 9 until the reinforcing nut 10 is in close contact with the connecting seat 1, which can further fix the position of the limit rod 9 so that it will not change its position arbitrarily due to the increase in usage time, and then use the bearing connecting rod 7 to fix the two bearings 8 on one side of the mounting plate 6, and finally align the gap formed by the two spindle clamping holes 4 with the external spindle, and sleeve it on the outside of the spindle, and then turn the fixing screw 5. As one end of the fixing screw 5 is gradually screwed into the fixing plate 2, the other end of the fixing screw 5 will drive the clamping plate 3 to bend and approach the fixing plate 2 at the same time, so that the fixing plate 2 and the clamping plate 3 can be tightly wrapped around the outer wall of the spindle.

[0033] Although 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.
