Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to an easily adjustable wood clamping and fixing device. Background Technology

[0002] With the increasing diversification of modern home furnishing needs, consumers are placing higher demands on the personalized design of furniture. As an important part of daily life, modern furniture must not only possess excellent practicality but also aesthetic value and good adaptability to the spatial environment. Furniture is assembled from materials such as wood. When designing furniture, it is necessary to first determine its dimensions and overall shape. This process often involves processing steps such as cutting and drilling wood, all of which require the use of fixing devices to limit the movement of the wood.

[0003] However, traditional wood fixing devices mostly use two telescopic devices to clamp the two sides of the wood. Although this can achieve basic fixation of the workpiece to a certain extent, it is prone to vibration or displacement during processing, which leads to a decrease in processing accuracy and affects the quality of the final product. Utility Model Content

[0004] The purpose of this invention is to provide an easily adjustable wood clamping and fixing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An easily adjustable wood clamping and fixing device includes a housing. The bottom inner side of the housing has an arc-shaped groove. Centering clamping devices are symmetrically fixedly installed on both sides of the housing. A top plate is fixedly installed on the top of the housing. A lifting cylinder is installed on the top of the top plate. A lifting plate is provided below the top plate. The top of the lifting plate is fixedly connected to the output shaft of the lifting cylinder. Arc-shaped plates are slidably connected to both sides of the bottom of the lifting plate. A countersunk hole is provided in the center of each of the two arc-shaped plates. A spike is fixedly installed in each of the two countersunk holes by bolts. The tips of the two spikes are both set downward and protrude from the arc surface of the arc-shaped plate.

[0007] Furthermore, two limiting rods are installed on each side of the lifting plate, and one end of each of the limiting rods is fixedly connected to the bottom of the housing, and the other end is fixedly connected to the top of the housing.

[0008] Furthermore, limiting blocks are provided on both sides of the top of the two arc-shaped plates, and limiting holes are provided on both sides of the lifting plate. Several limiting blocks are slidably connected in the corresponding limiting holes.

[0009] Furthermore, several of the limiting blocks extend through the limiting holes to the top of the lifting plate, and a limiting plate is fixedly installed at the end. The width of each of the limiting plates is greater than the width of the limiting holes. A certain gap is left between the lower surface of the limiting plate and the upper surface of the lifting plate. Each of the lower surfaces of the limiting plates is provided with four rollers. The rollers are arranged in pairs and are located on both sides of the lower surface of the limiting plate, abutting against the upper end surface of the lifting plate.

[0010] Furthermore, slots are provided on the outward-facing side of the lifting plate and on one side of the two limiting blocks, and insert rods are inserted into the slots where the limiting blocks communicate with the lifting plate.

[0011] Furthermore, anti-slip pads are provided on the lower arc surfaces of the two arc-shaped plates, and the tip of the spike is located below the anti-slip pads.

[0012] Furthermore, both of the centering clamping devices include telescopic cylinders fixedly installed outside the housing. The telescopic end of the telescopic cylinder penetrates the side wall of the housing and extends into the housing. An abutment is fixedly installed at the end of the telescopic cylinder located inside the housing.

[0013] The beneficial effects of this utility model are:

[0014] In use, the wood is first placed in the arc-shaped groove. Then, the centering clamping devices on both sides are activated, causing them to move towards the center and push the wood to the center position. During this process, the positions of the two arc-shaped plates are adjusted according to the position and size of the wood. After adjustment, the centering clamping devices are reset. Then, the lifting cylinder is activated, and its output shaft drives the lifting plate downward, driving the two arc-shaped plates to press synchronously against the surface of the wood. While the arc-shaped plates are pressing the wood, the spikes will pierce the surface of the wood to increase the fixing effect. After the arc-shaped plates have completed the pressing action, the centering clamping devices are activated again. The centering clamping devices clamp the two ends of the wood, so that they work together with the arc-shaped plates to fix the wood, achieving double fixing of the wood and ensuring that the wood will not shift during processing.

[0015] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

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

[0023] Please refer to Figure 1-5 ;

[0024] An easily adjustable wood clamping and fixing device includes a housing 1. An arc-shaped groove 11 is provided on the inner bottom of the housing 1 for placing and limiting the position of the wood. A centering clamping device 2 is symmetrically fixedly installed on both sides of the housing 1, pushing the wood to the center position. A top plate 3 is fixedly installed on the top of the housing 1, and a lifting cylinder 4 is installed on the top of the top plate 3. A lifting plate 5 is located below the top plate 3. The top of the lifting plate 5 is fixedly connected to the output shaft of the lifting cylinder 4. Arc-shaped plates 6 are slidably connected to both sides of the lifting plate 5. By activating the lifting cylinder 4, its output shaft drives the lifting plate 5 to move up and down, thereby driving the two arc-shaped plates 6 to simultaneously apply pressure to the upper surface of the wood, achieving downward compression and fixing of the wood, and improving the stability of the fixing. Simultaneously, by adjusting the position of the two arc-shaped plates 6, it can accommodate wood of different sizes, improving the applicability of the device. Both curved plates 6 have countersunk holes 61 in their centers. Each countersunk hole 61 is fixed with a spike 62 by bolts. The tips of the spikes 62 are set downwards and protrude from the curved surface of the curved plate 6. During the process of the curved plate 6 pressing the wood, the tips of the spikes 62 will insert into the surface of the wood to further enhance the fixing effect and prevent the wood from shifting during processing.

[0025] In use, the wood is first placed in the arc-shaped groove 11. Then, the centering clamping devices 2 on both sides are activated, causing them to move towards the center and push the wood to the center position. During this process, the positions of the two arc-shaped plates 6 are adjusted according to the position and size of the wood. After the adjustment is completed, the centering clamping devices 2 are reset. Then, the lifting cylinder 4 is activated, and its output shaft drives the lifting plate 5 to move downward, driving the two arc-shaped plates 6 to press against the surface of the wood simultaneously. While the arc-shaped plates 6 are pressing the wood, the spikes 62 will pierce into the surface of the wood to increase the fixing effect. After the arc-shaped plates 6 have completed the pressing action, the centering clamping devices 2 are activated again. The centering clamping devices 2 clamp the two ends of the wood, so that they work together with the arc-shaped plates 6 to fix the wood, achieving double fixing of the wood and ensuring that the wood will not shift during processing.

[0026] In this embodiment, two limiting rods 51 are installed on each side of the lifting plate 5. One end of each limiting rod 51 is fixedly connected to the bottom of the housing 1, and the other end is fixedly connected to the top of the housing 1. The lifting plate 5 moves along the limiting rods 51 during the lifting process. The guiding effect of the limiting rods 51 ensures the stability of the movement of the lifting plate 5 and avoids uneven pressing force due to deviation.

[0027] In this embodiment, limiting blocks 63 are provided on both sides of the top of the two arc-shaped plates 6, and limiting holes 52 are provided on both sides of the lifting plate 5. Several limiting blocks 63 are slidably connected in the corresponding limiting holes 52. The sliding of the limiting blocks 63 in the limiting holes 52 enhances the stability of the arc-shaped plates 6 when moving. Several limiting blocks 63 extend through the limiting holes 52 to the top of the lifting plate 5, and limiting plates 64 are fixedly installed at their ends. The width of several limiting plates 64 is greater than the width of the limiting holes 52, which can prevent the arc-shaped plates 6 from falling off. There is a certain gap between the lower surface of the limiting plates 64 and the upper surface of the lifting plate 5. Four rollers 65 are provided on the lower surface of several limiting plates 64. The rollers 65 are arranged in pairs, located on both sides of the lower surface of the limiting plates 64, and abut against the upper end surface of the lifting plate 5. The design of the rollers 65 reduces the friction between the limiting plates 64 and the lifting plate 5, and improves the smoothness of the position adjustment of the arc-shaped plates 6.

[0028] In this embodiment, slots 53 are provided on the outward side of the lifting plate 5 and on one side of the two limiting blocks. Insert rods 54 are inserted into the slots 53 that connect the limiting blocks and the lifting plate 5 to limit the arc plate 6 and ensure that it remains stable in the non-adjusted state.

[0029] In this embodiment, anti-slip pads 66 are provided on the lower arc surfaces of the two arc plates 6. The tip of the spike 62 is located below the anti-slip pads 66, which will not affect the insertion of the spike 62 into the wooden board. The anti-slip pads 66 increase the friction between the spike and the wood, further improving the fixing effect on the wood.

[0030] In this embodiment, both centering and clamping devices 2 include telescopic cylinders 21 fixedly installed outside the housing 1. The telescopic end of the telescopic cylinder 21 penetrates the side wall of the housing 1 and extends into the housing 1. An abutment 22 is fixedly installed at the end of the telescopic cylinder 21 located inside the housing 1. By activating the telescopic cylinder 21, its telescopic end can drive the abutment 22 to move towards the center, thereby realizing the centering and clamping operation of the wood. Preferably, the telescopic cylinder 21 has a built-in pressure sensor for real-time monitoring of the cylinder's working pressure. After setting a predetermined value for the pressure sensor, when the pressure caused by the telescopic cylinder 21 clamping the wood reaches that value, a signal is transmitted to the control system. The system will then stop the extension action of the telescopic cylinder 21 to prevent damage to the cylinder or wood due to excessive clamping force.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
