Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a splicing tooling and fixture for reinforcing the chassis of military special vehicles. Background Technology

[0002] In the production, manufacturing and maintenance of military special vehicles, chassis reinforcement is a crucial process that directly affects the vehicle's load-bearing capacity, structural strength and service life. To ensure the quality of reinforcement work, tooling fixtures must be used to accurately and securely position and clamp the massive and heavy vehicle chassis.

[0003] Currently, most of the tooling fixtures used are special fixtures designed for specific chassis models. Although they are structurally stable and have high positioning accuracy, military special vehicles come in a wide variety of models and have different specifications and dimensions. Every time a chassis model is changed, a set of special fixtures needs to be replaced or redesigned. This not only leads to a sharp increase in production costs, but also greatly reduces the flexibility and efficiency of the production line.

[0004] To overcome the problem of poor versatility of dedicated fixtures, some combined or spliced ​​fixtures consisting of a base and multiple movable clamping units have emerged. These fixtures adapt to chassis of different sizes by rearranging the positions of the clamping units on the base, thus improving the equipment's versatility. However, the clamping units of these fixtures are usually connected to the base by direct bolt fastening or T-block locking. The rigidity and reliability of this connection method are insufficient when facing chassis reinforcement operations. Chassis reinforcement is usually accompanied by high-impact operations such as welding and riveting. The huge vibrations and impacts generated will act on the entire fixture system, which can easily cause slight loosening or displacement at the connection between the clamping unit and the base, thereby compromising the initial positioning accuracy of the chassis and ultimately affecting the reinforcement quality.

[0005] Therefore, this utility model proposes a splicing tooling fixture for reinforcing the chassis of military special vehicles to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the splicing tooling fixture for reinforcing military special vehicle chassis, such as insufficient rigidity of the connection between the clamping unit and the workbench, easy displacement under the impact and vibration of the reinforcement operation, which affects the positioning accuracy, and poor versatility for different chassis models, this utility model aims to provide a splicing tooling fixture for reinforcing military special vehicle chassis with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a splicing tooling fixture for reinforcing the chassis of military special vehicles, including: a workbench, a clamping mechanism and a fixing mechanism; as well as an insert plate, a fixing plate, a slide bar and a hydraulic rod.

[0008] The fixing mechanism and the clamping mechanism are connected by a plug-in connection to form a detachable rigid lock, and the outer wall of the support frame of the clamping mechanism is provided with an installation groove.

[0009] Furthermore, the fixing mechanism includes a fixing frame, a threaded rod and a sliding rod installed in the fixing frame, the fixing plate being threadedly engaged with the threaded rod and slidably sleeved on the sliding rod, and the insert plate being connected to the fixing plate; the clamping mechanism includes a clamping plate and a hydraulic rod for driving the clamping plate; the structure of the insert plate is adapted to the mounting groove, and by rotating the threaded rod, the fixing plate is driven to translate along the sliding rod, thereby causing the insert plate to insert into or disengage from the mounting groove, realizing the locking or unlocking between the fixing mechanism and the clamping mechanism.

[0010] Preferably, the fixing mechanism further includes a turntable, which is coaxially connected to one end of the threaded rod and is used to drive the threaded rod to rotate.

[0011] Preferably, the fixing plate has a threaded hole that mates with the threaded rod and a through hole that mates with the slide rod.

[0012] Preferably, the clamping mechanism further includes a connecting frame and a connecting rod, the connecting frame being connected to the top end of the hydraulic rod, and the clamping plate being connected to the connecting frame via the connecting rod.

[0013] Preferably, the connecting frame is a plate-shaped structure, and the connecting rod is hinged between the connecting frame and the clamping plate.

[0014] Preferably, there are two clamping plates, and the two clamping plates are arranged symmetrically about the central axis of the hydraulic rod.

[0015] Preferably, the top wall of the workbench is equipped with a plurality of fixing mechanisms and a plurality of clamping mechanisms along a preset array.

[0016] Preferably, the fixing mechanism is disposed on one side of the clamping mechanism, and the movement direction of the insert plate is perpendicular to the wall surface of the support frame where the mounting groove is provided.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problems of poor versatility of existing tooling fixtures and insufficient stability of the connection between the clamping unit and the worktable, which easily leads to displacement during reinforcement operations and affects positioning accuracy. It achieves the technical effect of flexibly arranging clamping points according to different chassis and realizing high-strength locking, which significantly improves the versatility of the fixture and the positioning stability during operation.

[0019] 2. This utility model, by adopting a combination structure of turntable, threaded rod and slide rod in the fixed mechanism, stably converts the rotation operation into the linear motion of the insert plate, which solves the problems of complex structure or insufficient locking force of traditional locking devices. It achieves the technical effect of simple structure, convenient operation and reliable locking. This mechanical structure can provide huge locking force and has self-locking property, and can effectively resist the impact and vibration during the processing.

[0020] 3. This utility model solves the problem of insufficient clamping force or unstable clamping process for heavy workpieces by using a hydraulic rod to drive the clamping plate in the clamping mechanism. It achieves the technical effect of providing a strong, stable and easy-to-control clamping force, ensuring that the heavy chassis is firmly fixed and further guaranteeing the quality and accuracy of the reinforcement operation.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 4 This utility model provides a modular tooling fixture for reinforcing military special vehicle chassis, which aims to solve the problems of insufficient stability and poor versatility in the connection between the clamping unit and the worktable 1 in existing tooling fixtures. Figure 1 and Figure 2 As shown, the military special vehicle chassis reinforcement splicing tooling fixture includes a workbench 1, and at least one clamping mechanism 3 and at least one fixing mechanism 2 detachably mounted on the top wall of the workbench 1. The workbench 1 serves as the mounting base for the entire device. The clamping mechanism 3 and the fixing mechanism 2 cooperate with each other to achieve flexible arrangement and stable clamping of the vehicle chassis. The fixing mechanism 2 is used to detachably lock the clamping mechanism 3 onto the workbench 1, while the clamping mechanism 3 is used to directly clamp and fix the vehicle chassis.

[0030] To solve the above-mentioned technical problems, the technical solution of this embodiment lies in the specific detachable locking structure formed between the fixing mechanism 2 and the clamping mechanism 3. Please refer to the following for details. Figure 3 and Figure 4 The structure will be described in detail below:

[0031] The fixing mechanism 2 includes a fixing frame 202, and a threaded rod 204 and a sliding rod 205 installed in the fixing frame 202. The fixing frame 202 is fixedly installed on the top wall of the workbench 1 by bolts or other means. The threaded rod 204 and the sliding rod 205 are arranged parallel to each other in the fixing frame 202. The fixing mechanism 2 also includes a fixing plate 203 that is threadedly engaged with the threaded rod 204. The fixing plate 203 is slidably sleeved on the outer wall of the sliding rod 205. An insert plate 201 is connected to the fixing plate 203. The fixing mechanism 2 also includes a turntable 206. The turntable 206 is coaxially connected to one end of the threaded rod 204. Its function is that when the turntable 206 is rotated, the rotational motion is converted into the linear translational motion of the fixing plate 203 along the sliding rod 205 through the engagement of the threaded rod 204 and the fixing plate 203, thereby driving the insert plate 201.

[0032] Meanwhile, the outer wall of the support frame 305 of the clamping mechanism 3 is provided with a mounting groove 306 that matches the shape and size of the insert plate 201. When it is necessary to lock the clamping mechanism 3, the turntable 206 is rotated to drive the insert plate 201 into the mounting groove 306. This threaded pin-type locking structure ensures that the clamping mechanism 3 and the worktable 1 form extremely high locking force and connection rigidity, effectively preventing displacement caused by vibration or impact during reinforcement operations and ensuring positioning accuracy.

[0033] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0034] As a preferred embodiment, in order to facilitate the operator to drive the threaded rod 204, the fixing mechanism 2 also includes a turntable 206, which is coaxially connected to one end of the threaded rod 204, and its structure facilitates manual rotation; specifically, the fixing plate 203 is provided with a threaded hole that cooperates with the threaded rod 204 and a through hole that cooperates with the slide rod 205. This structure ensures that the fixing plate 203 can be accurately guided and translated along the slide rod 205 when the threaded rod 204 rotates.

[0035] For a preferred embodiment of the internal transmission structure of the clamping mechanism 3, please refer to [reference needed]. Figure 4 The clamping mechanism 3 also includes a connecting frame 302 and a connecting rod 303. The connecting frame 302 is a plate-shaped structure and is fixedly connected to the top of the hydraulic rod 304. The clamping plate 301 is connected to the connecting frame 302 through the connecting rod 303. More specifically, the connecting rod 303 is hinged between the connecting frame 302 and the clamping plate 301 to form a linkage transmission mechanism. Preferably, there are two clamping plates 301, and the two clamping plates 301 are symmetrically arranged about the central axis of the hydraulic rod 304 to achieve synchronous and centered clamping.

[0036] To achieve the modular function of this solution, multiple fixing mechanisms 2 and multiple clamping mechanisms 3 can be installed on the top wall of the workbench 1 along a preset array. In the specific spatial layout, the fixing mechanism 2 is set on one side of the clamping mechanism 3, and the movement direction of the insert plate 201 is perpendicular to the wall surface of the support frame 305 where the mounting groove 306 is opened, thereby forming a stable orthogonal lock.

[0037] Working principle: Multiple fixing mechanisms 2 are equidistantly installed on the top wall of the workbench 1, and multiple clamping mechanisms 3 are installed on the top wall of the workbench 1. The fixing mechanisms 2 are used to fix the clamping mechanisms 3. After the clamping mechanisms 3 are installed on the workbench 1, the turntable 206 is rotated. The turntable 206 drives the threaded rod 204 to rotate in the fixed frame 202. After the threaded rod 204 rotates, it drives the fixing plate 203 on its outer wall, so that the fixing plate 203 slides along the outer wall of the slide rod 205. When the fixing plate 203 slides, it drives the insert plate 201 to insert into the mounting groove 306 on the outer wall of the support frame 305, forming a stable connection and preventing the structure from loosening.

[0038] The clamping mechanism 3 includes a support frame 305. The outer wall of the support frame 305 has an installation groove 306, which facilitates the insertion of the insert plate 201. The inner side of the support frame 305 has a hydraulic rod 304. In use, the hydraulic rod 304 drives the connecting frame 302 at the top to move up and down. When the connecting frame 302 moves, it pulls the connecting rod 303, which in turn pulls the clamping plate 301, causing the clamping plate 301 to open and close, thereby fixing the chassis and improving positioning accuracy.
