Description

Technical Field

[0001] This utility model relates to the field of furniture processing technology, and in particular to a grooving device for solid wood furniture processing. Background Technology

[0002] With the continuous development of solid wood furniture manufacturing technology, grooving of boards, as the core process of furniture component processing, directly affects the precision of furniture assembly and structural stability. In the production of solid wood tables and chairs, cabinets and decorative furniture, the surface of the boards needs to be processed with various types of groove structures, such as rectangular grooves for mortise and tenon joints, T-shaped grooves for installing metal fittings and curved grooves for decorative lines. Different groove structures have different requirements for the cutting edge shape, cutting angle and size specifications of grooving tools. In the traditional processing, each time a different groove type is changed, a grooving tool with a specific structure needs to be replaced.

[0003] However, existing board grooving equipment generally uses bolt fastening or chuck locking for tool fixing. When changing tools, a special wrench is needed for multi-step disassembly. Especially when small furniture companies carry out multi-variety customized production, the frequency of tool replacement per day is too high, resulting in a low proportion of effective processing time for the equipment and a reduction in overall production efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a board grooving device for solid wood furniture processing, so as to solve the problem that the existing board grooving equipment is cumbersome and troublesome when changing the cutting tools, resulting in a low proportion of effective processing time and a reduction in overall production efficiency.

[0005] To achieve the above objectives, this utility model provides a grooving device for solid wood furniture processing, including a mobile grooving machine, and further comprising:

[0006] A drive motor is installed inside the mobile grooving machine. A drive connecting shaft is connected to the outside of the drive motor. A central mounting groove is provided through the center of the drive connecting shaft. An annular locking groove is provided around the middle of the inner side wall of the central mounting groove. An annular magnet is installed on the top of the central mounting groove.

[0007] A grooving tool is positioned below the drive connecting shaft. A central connecting shaft is connected to the center of the grooving tool. The central connecting shaft and the central mounting slot are mutually fitted. The grooving tool is inserted into the central mounting slot and connected to the drive connecting shaft via the central connecting shaft. The drive motor drives the grooving tool to rotate via the drive connecting shaft and the central connecting shaft. A connecting magnet is installed at the top of the central connecting shaft.

[0008] An inclined guide sleeve is disposed inside the central connecting shaft. A centrifugal locking pin is slidably nested inside the inclined guide sleeve, and the centrifugal locking pin is configured to cooperate with the annular locking groove.

[0009] Furthermore, a main gear is connected to the shaft end of the drive motor, and a secondary gear is connected around the outer side of the drive connecting shaft. The secondary gear and the main gear are meshed with each other, and the drive motor drives the connecting shaft to rotate through the main gear and the secondary gear.

[0010] Furthermore, a guide sleeve is provided above the drive connecting shaft, and an unloading push rod is slidably nested inside the guide sleeve. When the unloading push rod moves downward along the guide sleeve, it passes through the annular magnet and presses against the central connecting shaft to slide downward synchronously. An electromagnetic coil is installed in the middle of the guide sleeve.

[0011] Furthermore, it also includes a processing platform located below the mobile grooving machine. A contour guide plate is provided in the middle of the processing platform, and a guide wheel is arranged around the bottom outer side of the drive connecting shaft. The guide wheel and the contour guide plate are configured to cooperate with each other, and the mobile grooving machine is guided to move along the edge of the contour guide plate by the guide wheel.

[0012] Furthermore, a positioning mounting block is installed on the surface of the processing platform, and a positioning mounting groove is provided in the middle of the contour guide plate. The positioning mounting block and the positioning mounting groove are configured to cooperate with each other.

[0013] Furthermore, a vacuum adsorption platform is installed in the middle of the processing platform. Conical adsorption grooves are evenly distributed on the surface of the vacuum adsorption platform. A sealing ball is installed at the bottom of the conical adsorption groove. A sealing spring is connected below the sealing ball. A vacuum adsorption chamber is installed inside the vacuum adsorption platform. A vacuum pump is installed in the middle of the vacuum adsorption chamber. The vacuum pump is interconnected with all the conical adsorption grooves through the vacuum adsorption chamber.

[0014] The beneficial effects of this utility model are as follows: As can be seen from the above description, the grooving device for solid wood furniture processing provided by this utility model allows the grooving tool to be directly inserted into the central mounting groove of the drive connecting shaft for connection and installation. It is also connected and firmly attracted to the annular magnet through the connecting magnet.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a grooving device for solid wood furniture processing includes a mobile grooving machine, and further includes:

[0027] The drive motor is located inside the mobile grooving machine. A drive connecting shaft is connected to the outside of the drive motor. A central mounting groove is provided through the center of the drive connecting shaft. An annular locking groove is provided around the middle of the inner side wall of the central mounting groove. An annular magnet is installed on the top of the central mounting groove.

[0028] A grooving cutter is positioned below the drive connecting shaft. A central connecting shaft is connected to the center of the grooving cutter. The central connecting shaft and the central mounting slot are designed to cooperate with each other. The grooving cutter is inserted into the central mounting slot and connected to the drive connecting shaft through the central connecting shaft. The drive motor drives the grooving cutter to rotate through the drive connecting shaft and the central connecting shaft. A connecting magnet is installed at the top of the central connecting shaft.

[0029] An inclined guide sleeve is located inside the central connecting shaft. A centrifugal locking pin is nested and slidably arranged on the inner side of the inclined guide sleeve. The centrifugal locking pin and the annular locking groove are configured to cooperate with each other.

[0030] In this embodiment, the drive motor 301 of the device drives the grooving cutter 5 to rotate via the drive connecting shaft 4 and the central connecting shaft 501 to perform grooving on the sheet metal. When the cutter needs to be replaced, the selected grooving cutter 5 is directly inserted into the central mounting groove 403 of the drive connecting shaft 4 via its central connecting shaft 501 until the connecting magnet 504 and the ring magnet 405 are in full contact and firmly attracted together. At this time, the grooving cutter 5 is kept basically stable by magnetic force. Then, the mobile grooving machine 3 is started. As the drive motor 301 drives the drive connecting shaft 4 to start rotating, the grooving cutter 5 will also rotate at high speed. During this process, due to the centrifugal force, the tilting guide... The centrifugal locking pin 503 inside the sliding sleeve 502 will automatically slide outward and eventually embed into the annular locking groove 404 to complete the locking process, thereby locking the tool during the processing. After stopping grooving and turning off the drive motor 301, as the speed decreases, because the inclined guide sleeve 502 is inclined towards the center of the central connecting shaft 501, the centrifugal locking pin 503 will reset along the inclined guide sleeve 502 under the action of gravity, releasing the lock. At this time, the grooving tool 5 can be directly pulled out from the central mounting groove 403 to prepare a new tool for the next operation, which facilitates quick replacement of grooving tools 5 of different specifications and shapes, making it safer and more convenient to use.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, preferably, a main gear 302 is connected to the shaft end of the drive motor 301 of the device, and a secondary gear 401 is connected around the outer side of the drive connecting shaft 4. The secondary gear 401 and the main gear 302 are meshed with each other. The drive motor 301 drives the connecting shaft 4 to rotate through the main gear 302 and the secondary gear 401. At the same time, a guide sleeve 303 is provided above the drive connecting shaft 4, and an unloading push rod 304 is slidably nested inside the guide sleeve 303. An electromagnetic coil 305 is installed in the middle of the guide sleeve 303, so that when it is necessary to disassemble the tool, the electromagnetic coil 305 drives the ferromagnetic unloading push rod 304. Moving downwards along the guide sleeve 303, the bottom of the unloading push rod 304 passes through the annular magnet 405 and presses against the central connecting shaft 501, sliding downwards synchronously to achieve automatic tool disassembly. This simplifies the operation steps and improves work efficiency. When installing the tool, the central connecting shaft 501 synchronously presses upwards to reset the unloading push rod 304. At this time, the unloading push rod 304 moves in the electromagnetic coil 305. Due to the principle of electromagnetic induction, a reverse electromotive force, i.e., a reverse current, is generated in the electromagnetic coil 305. The change in the reverse current can be used to detect whether the central connecting shaft 501 is installed in place, thus improving the overall performance and reliability of the equipment.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, preferably, the device also includes a processing platform 1, which is located below the mobile grooving machine 3 to support the plate to be processed and ensure its stability during processing. A contour guide plate 102 is provided in the middle of the processing platform 1, and a guide wheel 402 is arranged around the bottom outer side of the drive connecting shaft 4. The guide wheel 402 and the contour guide plate 102 are arranged in cooperation with each other. The guide plate is designed into a specific shape according to different processing requirements to guide the grooving machine to make precise path movement, realize the height control of the grooving path, and facilitate the processing of grooving with complex geometric shapes.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, preferably, positioning mounting blocks 101 are installed on the surface of the processing platform 1 according to predetermined positions and specifications. These positioning mounting blocks 101 are used to fix the contour guide plate 102 and ensure that it does not shift during processing. The middle part of the contour guide plate 102 is designed with a positioning mounting groove 103 that matches the positioning mounting block 101. When the contour guide plate 102 is placed on the processing platform 1, the positioning mounting groove 103 will accurately fit onto the positioning mounting block 101, ensuring that the position of the contour guide plate 102 is accurate. The matching design between the positioning mounting block 101 and the positioning mounting groove 103 allows the contour guide plate 102 to be quickly and accurately positioned and fixed on the processing platform 1. When it is necessary to replace the contour guide plate 102 with one of different shapes or sizes to adapt to different processing requirements, the existing guide plate can be easily removed by simply lifting it from the positioning mounting block 101 and then replacing it with a new guide plate. The whole process is simple and quick, without complicated adjustment steps.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, preferably, a vacuum adsorption platform 2 is installed in the middle of the processing platform 1 of the device for fixing the plate to be processed. Conical adsorption grooves 202 are evenly distributed on the surface of the platform. Sealing balls 203 are installed at the bottom of the conical adsorption grooves 202. These conical adsorption grooves 202 help improve the adsorption effect and adapt to plates of different thicknesses. A sealing spring 204 is connected below the sealing ball 203. A vacuum adsorption chamber 201 is installed inside the vacuum adsorption platform 201. A vacuum adsorption chamber 201 is installed in the middle of the vacuum adsorption chamber 201. A vacuum pump 205 is provided, which is connected to all the conical adsorption tanks 202 through a vacuum adsorption chamber 201. When the vacuum pump 205 is started, a negative pressure is formed in the vacuum adsorption chamber 201. The sealing ball 203 moves downward under the influence of the internal negative pressure to close the open conical adsorption tanks 202. The conical adsorption tanks 202 covered by the plate are closed by the plate, and the overall internal pressure remains negative. The sealing ball 203 remains in place, so that the plate can be firmly adsorbed on the platform. The vacuum adsorption platform 2 facilitates the quick fixation and release of the plate to be processed, making it more convenient and faster to use.

[0035] The grooving device for solid wood furniture processing provided by this utility model has a grooving cutter 5 that is directly inserted into the central mounting groove 403 of the drive connecting shaft 4 via its central connecting shaft 501. It is also connected and firmly attracted to the annular magnet 405 via the connecting magnet 504. During high-speed rotation, the centrifugal locking pin 503 automatically slides outward and inserts into the annular locking groove 404, ensuring the stability of the grooving cutter 5 in the working state. After processing stops, the locking mechanism can automatically unlock, which facilitates quick replacement of grooving cutters 5 of different specifications and shapes, making it safer and more convenient to use.
