Description

Technical Field

[0001] This utility model relates to the field of tooling fixture technology, and in particular to a height-adjustable tooling fixture. Background Technology

[0002] Tooling fixtures are key tools used to fix, position, and support workpieces, directly affecting production efficiency, assembly accuracy, and product quality. As the manufacturing industry moves towards flexibility and intelligence, higher demands are placed on the adaptability, adjustment efficiency, and precision of tooling fixtures, making the development of height-adjustable tooling fixtures an inevitable trend.

[0003] However, traditional tooling fixtures have significant limitations in design. These fixtures mostly adopt a one-piece molded fixed structure, and their height remains unchanged after manufacturing and processing, making it difficult to flexibly adjust according to differences in workpiece size or actual process requirements. Therefore, a height-adjustable tooling fixture is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a height-adjustable tooling fixture, which aims to improve the problem mentioned in the prior art that "traditional tooling fixtures are difficult to flexibly adjust the height according to the workpiece size".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a height-adjustable tooling fixture, including a fixed platform, mounting holes are provided on both the front and back sides of the fixed platform, a transverse threaded hole is provided on the right side of the fixed platform, a longitudinal threaded hole is provided on the bottom of the fixed platform, a threaded fastener is threaded into the transverse threaded hole, and an adjustment mechanism and an auxiliary mechanism are provided at the bottom of the fixed platform.

[0006] The adjusting mechanism includes a threaded column, which is threadedly connected inside a longitudinal threaded hole. A support plate is fixedly connected to the bottom end of the threaded column, and a locking nut is threadedly connected to the outer wall of the threaded column.

[0007] As a further description of the above technical solution:

[0008] The auxiliary mechanism includes a fixing ring, which is fixedly connected to the bottom inner wall of the fixed platform. The fixing ring is a hollow ring structure.

[0009] As a further description of the above technical solution:

[0010] A rubber ring is fixedly connected to the lower surface of the fixing ring.

[0011] As a further description of the above technical solution:

[0012] The lower surface of the rubber ring is fixedly connected with a first protrusion and a second protrusion.

[0013] As a further description of the above technical solution:

[0014] Multiple sets of the first and second protrusions are provided, and the multiple sets of the first and second protrusions are arranged in a circumferential array on the lower surface of the rubber ring with the threaded column as the central axis.

[0015] As a further description of the above technical solution:

[0016] The transverse centerline of the mounting hole is on the same horizontal plane as the centerline of the threaded fastener.

[0017] As a further description of the above technical solution:

[0018] The threaded fastener is specifically a bolt with external threads.

[0019] As a further description of the above technical solution:

[0020] The mounting hole is a rectangular hole structure opened at an angle.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the height of the fixed platform can be flexibly adjusted through the design of the adjustment mechanism. After the workpiece is fixed inside the mounting hole, the height of the workpiece can be flexibly adjusted by moving the fixed platform up and down, thereby improving the flexibility of the tooling fixture to adapt to different installation needs.

[0023] 2. In this utility model, the design of the auxiliary mechanism can increase the friction between the locking nut and the fixed platform, thereby fully utilizing the locking effect of the locking nut and effectively preventing relative displacement between the locking nut and the fixed platform, thus improving the stability of the fixed platform.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a height-adjustable tooling fixture, including a fixed platform 1. The fixed platform 1 has mounting holes 2 on both its front and back sides. A workpiece is passed through the mounting holes 2, and the fixed platform 1, in conjunction with the mounting holes 2, supports the workpiece. The mounting holes 2 are rectangular holes with an inclined opening. A transverse threaded hole 3 is provided on the right side of the fixed platform 1, and a longitudinal threaded hole 4 is provided on the bottom of the fixed platform 1. A threaded fastener 5 is threaded inside the transverse threaded hole 3. Specifically, the threaded fastener 5 is a bolt with external threads. Rotating the threaded fastener 5 allows it to gradually advance inside the transverse threaded hole 3. At this time, the threaded fastener 5 can press the workpiece tightly inside the mounting hole 2. The transverse central axis of the mounting hole 2 and the central axis of the threaded fastener 5 are on the same horizontal plane. An adjustment mechanism 6 and an auxiliary mechanism 7 are provided at the bottom of the fixed platform 1.

[0032] Reference Figure 2 - Figure 3 The adjusting mechanism 6 includes a threaded post 61, which is threadedly connected to the inside of the longitudinal threaded hole 4. Rotating the threaded post 61, in conjunction with the threaded connection of the longitudinal threaded hole 4, allows the fixed platform 1 to move up and down on the outer wall of the longitudinal threaded hole 4, thereby adjusting the height of the workpiece inside the mounting hole 2. A support plate 62 is fixedly connected to the bottom end of the threaded post 61, and a locking nut 63 is threadedly connected to the outer wall of the threaded post 61. After adjustment, rotating the locking nut 63 causes its top to fit against the bottom of the fixed platform 1, at which point the bottom of the fixed platform 1 can be locked using the locking nut 63.

[0033] Reference Figure 2 - Figure 4The auxiliary mechanism 7 includes a fixing ring 71, which is fixedly connected to the bottom inner wall of the fixing platform 1. Since the fixing ring 71 is fixed to the bottom inner wall of the fixing platform 1, the rubber ring 72 can increase the friction between the locking nut 63 and the bottom of the fixing platform 1. The fixing ring 71 is a hollow ring structure, and the rubber ring 72 is fixedly connected to the lower surface of the fixing ring 71. The rubber ring 72 can increase the friction between the locking nut 63 and the fixing ring 71. The lower surface of the rubber ring 72 is fixedly connected to a first protrusion 73 and a second protrusion 74. Multiple sets of the first protrusion 73 and the second protrusion 74 are arranged in a circumferential array around the threaded column 61 as the central axis on the lower surface of the rubber ring 72. The multiple sets of staggered first protrusion 73 and second protrusion 74 can increase the roughness of the contact surface between the locking nut 63 and the rubber ring 72, thereby further improving the friction between the rubber ring 72 and the locking nut 63.

[0034] Working principle: Pass the workpiece through the mounting hole 2, and then rotate the threaded fastener 5 to gradually push it into the transverse threaded hole 3 until the threaded fastener 5 presses the workpiece into the mounting hole 2. Then rotate the threaded column 61, which, in conjunction with the threaded connection of the longitudinal threaded hole 4, allows the fixed platform 1 to move up and down on the outer wall of the longitudinal threaded hole 4. This allows for adjustment of the height of the workpiece inside the mounting hole 2, so that the height of the workpiece can be flexibly adjusted according to actual installation requirements. After adjustment, rotate the locking nut 63 so that its top fits against the bottom of the fixed platform 1. At this time, the bottom of the fixed platform 1 can be locked by the locking nut 63, thereby maintaining the fixed platform 1 at a fixed height and improving the stability of the fixed platform 1.

[0035] When the locking nut 63 is in contact with the bottom of the fixed platform 1 during rotation, the rubber ring 72 can increase the friction between the locking nut 63 and the fixed ring 71. Since the fixed ring 71 is fixed to the inner wall of the bottom of the fixed platform 1, the friction between the locking nut 63 and the bottom of the fixed platform 1 can be increased. At the same time, the roughness of the contact surface between the locking nut 63 and the rubber ring 72 can be increased by multiple sets of staggered first protrusions 73 and second protrusions 74. Under the same normal pressure, the rougher the contact surface, the greater the friction, which can further increase the friction between the rubber ring 72 and the locking nut 63, effectively avoiding relative displacement between the locking nut 63 and the fixed platform 1, thereby further improving the stability of the fixed platform 1.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
