Description

Technical Field

[0001] This invention relates to the field of debugging technology for detection and tracking equipment, and in particular to a rotation limiting device for leveling the envelope of a detection and tracking equipment. Background Technology

[0002] Some detection and tracking devices have an envelope component connected to the main body of the device via a U-shaped frame, and the envelope component can rotate relative to the U-shaped frame. Temporary limiting is required when leveling the envelope component.

[0003] Currently, during the leveling process, attempts have been made to use manual limiting, requiring at least two operators. This not only wastes manpower but also makes it difficult to guarantee leveling accuracy. Another approach involves placing a matching material between the U-shaped frame and the envelope to restrict the rotation of the envelope. However, this limiting method is limited by the shape of the envelope, the filling material needs to be determined based on the envelope shape and the support frame, and the limiting accuracy is generally coarse, sometimes even having negative effects, potentially failing to achieve the ideal leveling position.

[0004] Therefore, there is an urgent need for a rotational limiting device for leveling the envelope of a detection and tracking device that can solve the above-mentioned technical problems. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide a rotation limiting device for leveling the envelope of a detection and tracking device, thereby solving at least one of the aforementioned technical problems.

[0008] To achieve the above objectives, the present invention provides a rotation limiting device for leveling the envelope of a detection and tracking device, comprising:

[0009] A clamping and fixing mechanism includes a clamping frame, a clamping screw, and a clamping disc. A connecting block extending outwards is provided on the outer side of one side wall of the clamping frame, and a connecting screw hole is provided on the connecting block. One end of the clamping screw passes through the other side wall of the clamping frame and extends into the clamping frame, connecting to the clamping disc. The other end of the clamping screw is located outside the clamping frame and is threadedly connected to the clamping frame. Rotating the clamping screw adjusts the length of the clamping screw extending into the clamping frame and causes the clamping disc to move axially upwards along the clamping screw.

[0010] The limiting mechanism includes a limiting screw and a limiting plate. One end of the limiting screw passes through a connecting screw hole and is connected to the limiting plate. The limiting screw is threadedly connected to the connecting screw hole. Rotating the limiting screw causes the limiting plate to move axially along the limiting screw. The limiting screw is set to vertically clamp the screw.

[0012] Optionally, the end of the clamping screw facing the clamping disk is provided with a first ball head, and the side of the clamping disk facing the clamping screw is provided with a first ball joint seat. The first ball head and the first ball joint seat cooperate to realize the ball joint connection between the clamping screw and the clamping disk.

[0020] Optionally, the rotation limiting device also includes a force-applying rod, one end of which is provided with a sleeve hole;

[0021] The first and second force-bearing sections are both polygonal columns with the same cross-sectional shape and size. The cross-sectional shape matches the sleeve hole, allowing the force-applying rod to be fitted onto the polygonal column and drive the clamping screw and the limiting screw to rotate when needed.

[0022] (III) Beneficial Effects

[0023] The above-mentioned technical solution of the present invention has the following advantages: The rotation limiting device for leveling the envelope of the detection and tracking equipment provided by the present invention includes a clamping and fixing mechanism and a limiting mechanism. The clamping and fixing mechanism includes a clamping frame, a clamping screw, and a clamping disc. Rotating the clamping screw causes the clamping disc to clamp the object to be clamped, thus fixing the rotation limiting device. The limiting mechanism includes a limiting screw and a limiting disc. By rotating the limiting screw, the limiting disc moves along the axial direction of the limiting screw, causing the limiting disc to abut against the envelope, achieving friction limiting and preventing the envelope from rotating.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] See Figures 1-3 As shown, the rotation limiting device 1 for leveling the envelope of the detection and tracking device provided in this embodiment of the invention includes a clamping and fixing mechanism 11 and a limiting mechanism 12.

[0054] See Figure 2 and Figure 3As shown, the clamping and fixing mechanism 11 includes a clamping frame 111, a clamping screw 112, and a clamping disc 113. A connecting block 114 extending outwards is provided on the outer side of one side wall of the clamping frame 111. A connecting screw hole is provided on the connecting block 114. One end of the clamping screw 112 passes through the other side wall of the clamping frame 111 and extends into the clamping frame 111, connecting to the clamping disc 113. The other end of the clamping screw 112 is located outside the clamping frame 111, and the clamping screw 112 is threadedly connected to the clamping frame 111. Rotating the clamping screw 112 adjusts the length of the clamping screw 112 extending into the clamping frame 111, and drives the clamping disc 113 to move axially along the clamping screw 112, thereby adjusting the clamping distance to accommodate different sized parts. It should be noted that the clamping screw 112 is a rod with external threads. The clamping screw 112 is threadedly connected to the clamping frame 111. Its threaded portion can be a threaded hole provided on the side wall of the clamping frame 111, or it can consist of a nut provided on the side wall of the clamping frame 111 and a through hole coaxially arranged and passing through the side wall of the clamping frame 111. In order to reduce the wall thickness of the clamping frame 111 and ensure the strength of the threaded connection, it is preferable to adopt a scheme in which the nut and the through hole cooperate.

[0055] See Figure 2 and Figure 3 As shown, the limiting mechanism 12 includes a limiting screw 121 and a limiting disk 122. One end of the limiting screw 121 passes through a connecting screw hole and connects to the limiting disk 122, and the limiting screw 121 is threadedly connected to the connecting screw hole. Rotating the limiting screw 121 causes the limiting disk 122 to move axially along the limiting screw 121. The limiting screw 121 is arranged perpendicularly to the clamping screw 112.

[0056] See Figure 1 As shown, in use, the U-shaped frame 3 is placed inside the clamping frame 111, and the clamping screw 112 is rotated to make the clamping plate 113 press against the U-shaped frame 3, thus fixing the rotation limiting device 1. Then, by rotating the limiting screw 121, the limiting plate 122 moves along the axial direction of the limiting screw 121, so that the limiting plate 122 presses against the envelope 2, achieving friction limiting and preventing the envelope 2 from rotating relative to the U-shaped frame 3. This rotation limiting device is not only simple in structure, easy to use, and saves labor costs, but also, by adjusting the movement of the limiting plate 122 along the axial direction of the limiting screw 121, the tightness between the limiting plate 122 and the envelope 2 can be adjusted within a certain range, which can help level the envelope 2. Furthermore, due to the use of friction limiting, damage to the envelope 2 can be avoided to a certain extent.

[0057] To avoid excessive resistance to the rotating clamping screw 112 caused by the friction generated after the clamping disc 113 abuts against the U-shaped frame 3, in a preferred embodiment, the clamping screw 112 and the clamping disc 113 are connected by a ball joint. After the clamping disc 113 abuts against the U-shaped frame 3, the clamping disc 113 is subjected to friction and will not rotate synchronously with the clamping screw 112 (at this time, the clamping screw 112 rotates relative to the clamping disc 113), but will still undergo axial displacement on the axis of the clamping screw 112 as the clamping screw 112 moves axially, thereby continuously pressing against the U-shaped frame 3 and achieving effortless adjustment. In an optional embodiment, see... Figure 2 and Figure 4 As shown, the clamping screw 112 has a first ball head 1121 at one end facing the clamping plate 113, and the clamping plate 113 has a first ball joint seat 1131 on the side facing the clamping screw 112. The first ball head 1121 and the first ball joint seat 1131 cooperate to realize the ball joint connection between the clamping screw 112 and the clamping plate 113.

[0058] Similarly, to avoid excessive resistance to the rotation of the limiting screw 121 caused by the friction generated after the limiting disc 122 abuts against the envelope portion 2, in a preferred embodiment, the limiting screw 121 and the limiting disc 122 are connected by a ball joint. After the limiting disc 122 abuts against the envelope portion 2, it is subjected to friction and will not rotate synchronously with the limiting screw 121, but it will still move axially with the limiting screw 121, causing axial displacement on the axis of the limiting screw 121, thereby continuously pressing against the envelope portion 2 until the requirement is met. Throughout the process, the adjustment difficulty will not increase due to increased friction, achieving effortless adjustment. In an optional embodiment, see... Figure 2 and Figure 5 As shown, the end of the limiting screw 121 facing the limiting disk 122 is provided with a second ball head 1211, and the side of the limiting disk 122 facing the limiting screw 121 is a second ball joint seat 1221. The second ball head 1211 and the second ball joint seat 1221 cooperate to realize the ball joint connection between the limiting screw 121 and the limiting disk 122.

[0059] To increase friction and minimize damage to the U-shaped frame 3, in some preferred embodiments, a rubber clamping pad 1132 is provided on the side of the clamping disc 113 opposite to the clamping screw 112. The rubber clamping pad 1132 can be glued to the clamping disc 113 or fixed to the clamping disc 113 with screws. In addition, due to the deformable nature of the rubber clamping pad 1132, it also helps to fine-tune the axial movement of the clamping disc 113.

[0060] Similarly, in order to increase friction and minimize damage to the envelope portion 2, in some preferred embodiments, a rubber limiting pad 1222 is provided on the side of the limiting disc 122 opposite to the limiting screw 121. The rubber limiting pad 1222 can be glued to the limiting disc 122 or fixed to the limiting disc 122 by screws.

[0061] To minimize limitations on the shape of the clamping element, in some preferred embodiments, the clamping frame 111 is U-shaped or C-shaped. For example, it can be formed by bending a sheet into a U-shape or C-shape.

[0062] To facilitate applying rotational force to the clamping screw 112, in some preferred embodiments, a first force-receiving section 1122 is provided at the end of the clamping screw 112 facing away from the clamping disc 113, facilitating the application of force when rotating the clamping screw 112. The first force-receiving section 1122 may be a relatively large-diameter column structure that is easy to grip. It may also be a columnar structure of a specific shape, facilitating its use with tools such as wrenches. In one embodiment, the first force-receiving section 1122 is a polygonal column. For example, it may be a columnar structure with edges, such as a triangular, rectangular, or hexagonal cross-section, facilitating clamping with tools.

[0063] The second stress-bearing segment 1212 plays the same role as the first stress-bearing segment 1122 in the scheme, and it can adopt any of the schemes adopted by the first stress-bearing segment 1122 mentioned above, which will not be repeated here.

[0064] In a preferred embodiment, the second force-bearing segment 1212 and the first force-bearing segment 1122 are both polygonal columns. The two polygonal columns have the same cross-sectional shape and size, which facilitates operation using the same force-applying tool.

[0065] In a preferred embodiment, see Figure 2 , Figure 3 and Figure 6 As shown, the rotation limiting device also includes a force-applying rod 13, one end of which is provided with a sleeve hole. The cross-section of the sleeve hole matches the cross-sectional shape and size of the first force-bearing section 1122 and the second force-bearing section 1212, so that the force-applying rod 13 can be sleeved on the polygonal column and drive the clamping screw 112 and the limiting screw 121 to rotate when needed.

[0066] It should be noted that the U-shaped frame and the envelope in this embodiment are only examples of this embodiment. The rotation limiting device of this application can be used for components with the same or similar structure in the detection and tracking equipment with the same requirements, and there is no limitation here.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that not every embodiment contains only one independent technical solution, and in the absence of conflict between solutions, the various technical features mentioned in each embodiment can be combined in any way to form other implementation methods that can be understood by those skilled in the art.

[0068] Furthermore, without departing from the scope of the present invention, modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions of some of the technical features, shall not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
