Description

Technical Field

[0001] This utility model belongs to the field of mechanical design technology, and in particular relates to a multifunctional pressing and fixing device. Background Technology

[0002] Traditional and common methods for securing equipment typically employ a clamping mechanism combining left and right screws and clamping jaws. While widely used in the equipment industry, this method suffers from the following technical drawbacks:

[0003] (1) The installation and operation are complex. The installation of the left and right screws and the clamping claws requires certain professional skills and tools, which places high demands on the operators. During the installation process, the position of the screws and the angle of the clamps need to be precisely adjusted to ensure that the clamps can accurately fix the product, which increases the difficulty and time cost of installation. During the operation, the left and right screws need to be rotated at the same time to open and close the clamping claws, which is relatively cumbersome. Especially when it is necessary to frequently change products or adjust the position of the clamps, it will reduce work efficiency.

[0004] (2) Limited product adaptability. Clamping methods are usually designed for products of specific sizes and shapes. For products of different sizes, shapes or materials, different clamping claws or adjustments to the screw stroke may be required, resulting in poor versatility. For some products with soft or fragile surfaces, the clamping claws may damage the product surface during the fixing process, affecting the product's appearance and quality.

[0005] (3) Uneven distribution of locking force: The way the left and right screws drive the clamping claws may result in uneven distribution of locking force on the product surface. Due to the transmission method of the screws and the structural characteristics of the clamping claws, some parts of the clamping claws may exert greater pressure on the product, while other parts may exert less pressure. This will affect the stability of the product fixation and may cause the product to shift or deform in some applications where high fixation accuracy is required.

[0006] (4) The maintenance cost is relatively high. After long-term use, the left and right screws and the clamping claws are prone to wear and deformation, requiring regular inspection, maintenance and replacement. In particular, the threaded part of the screw is prone to wear due to the constant rotational force and friction, which affects the transmission accuracy and locking force, resulting in high maintenance costs.

[0007] To overcome the aforementioned technical problems, existing technologies have been improved, but they still suffer from limited product adaptability and complex structures that are difficult to disassemble and assemble.

[0008] For example, patent document CN103350355A discloses a small curved surface quick-clamping mechanism, including a base, a locking screw, a spring, a pressure plate, a support screw, a spherical washer assembly, a rubber pad, and an adjusting nut. The locking screw is vertically fixed to the base, passing through a through hole in the spring and an oblong hole in the middle of the pressure plate. The adjusting nut is screwed onto the top of the locking screw, with the lower part of the adjusting nut abutting against the spherical washer assembly. A rubber pad is installed at one end of the pressure plate, and the support screw is threaded through the other end of the pressure plate. The bottom end of the support screw abuts against the base, and the top end of the support screw has a handwheel. This product has limited adaptability, a fixed installation position, and is difficult to disassemble.

[0009] Therefore, it is necessary to design a clamping and fixing device that is simple in structure, easy to assemble and disassemble, adaptable to multiple angle pressure points, and uniformly stressed, in order to solve the problems that still exist in the existing technology.

[0013] Furthermore, the lower end of the spherical pressure seat is provided with a concave annular surface, and the upper end is provided with a stepped surface, with the bottom of the stepped surface recessed into a spherical groove.

[0014] Furthermore, the end cap of the pressure seat has a raised hollow cylinder on its surface. The hollow cylinder is placed on the stepped surface at the upper end of the spherical pressure seat. The diameter of the hollow cylinder is smaller than the inner diameter of the stepped surface and larger than the outer diameter of the floating rod.

[0015] Furthermore, the floating rod and the spherical pressure seat are connected by a ball joint.

[0016] Furthermore, the lower end of the floating rod is set as a ball head, which is embedded in the spherical groove at the upper end of the spherical pressure seat; the upper end of the floating rod is provided with a through hole, through which the handle passes.

[0017] Furthermore, the upper outer surface of the floating rod is threaded, and the floating rod is threadedly connected to the rotary bridge to adjust the distance between the pressing mechanism and the surface of the pressed product.

[0018] Furthermore, a gap 'a' is provided between the floating rod and the end cap of the pressure seat, so that the working range of the floating rod is 2.5° around the center of the ball head.

[0019] Furthermore, a fixed baffle is provided between the slewing bridge and the fastener B, and an movable gap b is provided between the fixed baffle and the slewing bridge.

[0020] Furthermore, the rotary bridge drives the clamping mechanism to rotate around the fixed core seat through the movable gap b.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] (1) This utility model has a simple structure through the structural design of the rotary bridge, the fixed core seat and the pressing mechanism and the setting of the gap b. It can be easily disassembled and assembled, and can press and fix the product from multiple angles and in all directions without detaching from the product's support frame, adapting to multiple angle pressing points.

[0023] (2) This utility model adjusts the distance between the pressing mechanism and the surface of the pressed product by setting a floating rod and a rotary bridge thread connection, so as to meet the needs of different fixed locking heights.

[0024] (3) By setting the lower end of the floating rod as a ball head and setting the gap a, the working range of the floating rod is 2.5° around the center of the ball head, which meets the product pressing and fixing requirements when the angle of the pressing and fitting surface is within 2.5°.

[0025] (4) By setting a concave annular surface at the lower end of the spherical pressure seat, this utility model avoids the risk of unreliable pressing caused by slight unevenness on the surface of the pressed product, thereby improving the reliability of the pressing and fixing of the device.

[0038] 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.

[0039] like Figures 1-9 As shown, this utility model embodiment provides a multi-functional pressing and fixing device, including a rotary bridge 2, a fixed core seat 8, and a pressing mechanism. The rotary bridge 2 is sleeved on the fixed core seat 8 and fixed by fastener B9. The pressing mechanism is installed at the other end of the rotary bridge 2. The fixed core seat 8 includes a base 801 and a mounting post 802. The mounting post 802 is disposed on the base 801, and the rotary bridge 2 is sleeved on the mounting post 802. In use, the base 801 is fixed to the product's support frame 10 by fastener A1. The multi-functional pressing and fixing device connects the fixed core seat 8 and the pressing mechanism through the rotary bridge 2, so that the pressing function and the fixing function are linked to achieve the pressing and fixing effect. The rotary bridge 2 is sleeved on the fixed core seat 8 using a rotary joint connection, which can achieve 360° all-round pressing and fixing of the product without detaching from the product's support frame, adapting to multi-angle pressing points. The multi-functional pressing and fixing device is as follows: Figure 1As shown, the rotating bridge 2 rotates around the fixed core seat 8 as follows: Figure 7 As shown.

[0040] In this embodiment, the clamping mechanism includes a floating rod 6, a pressure seat end cap 5, a spherical pressure seat 4, and a handle 3. The lower end of the floating rod 6 is connected to the pressure seat end cap 5 and the spherical pressure seat 4; the upper end of the floating rod 6 is connected to the handle 3. The lower surface of the spherical pressure seat 4 contacts and presses against the surface 11 of the product being pressed. Rotating the handle 3 can drive the floating rod 6 and the spherical pressure seat 4 to move up and down, achieving the effect of clamping and unlocking. The clamping mechanism is as follows... Figures 2-4 As shown.

[0041] In this embodiment, the lower end of the spherical pressure seat 4 is provided with a concave annular surface, and the upper end is provided with a stepped surface, the bottom of which is recessed into a spherical groove. The structure of the spherical pressure seat 4 is as follows: Figure 4 As shown, the ball joint at the lower end of the floating rod 6 is connected through a spherical groove. The concave annular surface avoids the risk of unreliable clamping caused by slight unevenness on the surface of the pressed product.

[0042] In this embodiment, the surface of the pressure seat end cap 5 is provided with a raised hollow cylinder. The hollow cylinder is placed on the stepped surface at the upper end of the spherical pressure seat 4. The diameter of the hollow cylinder is smaller than the inner diameter of the stepped surface and larger than the outer diameter of the floating rod 6. This ensures a reliable connection of the pressing mechanism, and the components are reliably fixed through dimensional matching, making them less prone to loosening.

[0043] In this embodiment, the floating rod 6 and the spherical pressure seat 4 are connected by a ball joint. This meets the product clamping and fixing requirements when the angle of the clamping contact surface is within 2.5°. The connection state between the floating rod 6 and the spherical pressure seat 4 is as follows: Figure 4 As shown.

[0044] In this embodiment, the lower end of the floating rod 6 is configured as a ball head, which is embedded in the spherical groove at the upper end of the spherical pressure seat 4; the upper end of the floating rod 6 is provided with a through hole, through which the handle 3 passes. The purpose of configuring it as a ball head is to adapt to working conditions where the angle between the surface of the pressed product and the horizontal plane is within the range of 2.5°.

[0045] In this embodiment, the upper outer surface of the floating rod 6 is threaded, and the floating rod 6 is threadedly connected to the rotary bridge 2 to adjust the distance between the pressing mechanism and the surface 11 of the pressed product. The threaded connection meets the requirements for different fixed locking heights.

[0046] In this embodiment, a gap a is provided between the floating rod 6 and the pressure seat end cover 5, so that the working range of the floating rod 6 is 2.5° around the center of the ball head.

[0047] In this embodiment, a fixed baffle 7 is provided between the rotary bridge 2 and the fastener 9, and a movable gap b is provided between the fixed baffle 7 and the rotary bridge 2. By providing the movable gap b, it is beneficial for the rotary bridge 2 to rotate around the fixed core seat 8. The connection structure between the fixed core seat 8, the rotary bridge 2, and the fastener 9 is as follows: Figures 5-6 As shown.

[0048] In this embodiment, the rotary bridge 2 drives the clamping mechanism to rotate around the fixed core seat 8 through the movable gap b, thereby achieving a multi-angle and all-round clamping function.

[0049] During operation, the first step is to assemble and fix the multi-functional clamping and fixing device: First, install one end of the rotary bridge 2 and the fixed baffle 7 on the fixed core seat 8 and fix them with fastener B9; at the same time, install the spherical pressure seat 4 and the pressure seat end cover 5 on the floating rod 6 in sequence, then connect the floating rod 6 to the other end of the rotary bridge 2, and then install the handle 3 on the upper end of the floating rod 6; finally, fix the assembled multi-functional clamping and fixing device on the product support frame 10 with fastener A1.

[0050] The second step is to perform the clamping and fixing operation: First, perform the 360° rotation adjustment, rotating the rotating bridge 2 360° around the fixed core seat 8, as follows: Figure 7 As shown; secondly, perform the action of adjusting the height of different pressing surfaces, quickly pull the handle 3 to make the bottom surface of the spherical pressing seat contact and fix it with the surface 11 of the product being pressed; finally, perform the adaptive 2.5° press and fixation between the surface 11 of the product being pressed and the spherical pressing seat 4, forcefully pull the handle 3 to make the spherical pressing seat 4 and the surface 11 of the product being pressed adaptive 2.5°, so as to achieve complete pressing and fixing of the product, and the workflow ends.

[0051] In use, the number of multi-functional clamping and fixing devices can be selected according to the surface conditions requiring clamping and fixing. When multiple multi-functional clamping and fixing devices are used simultaneously, the spacing between them should be greater than the circumference diameter formed when the rotating bridge 2 rotates 360° around the fixing core seat 8. For example... Figure 8 , Figure 9 The diagram shows the simultaneous use of multiple of the aforementioned multifunctional clamping and fixing devices. Figure 8 To assemble the main view, Figure 9 This is a top view of the assembly and a schematic diagram of its motion. Figure 9 In the figure, r is the rotation radius of the multi-functional clamping and fixing device. The positions of A, B, E and H of the multi-functional clamping and fixing device are when the multi-functional clamping and fixing device is rotated to the fixed and locked state. The positions of C and G of the multi-functional clamping and fixing device are when the multi-functional clamping and fixing device is rotated to the minimum unlocked state. The positions of D and F of the multi-functional clamping and fixing device are when the multi-functional clamping and fixing device is in the state of being fixed or unlocked during rotation.

[0052] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
