Description

Technical Field

[0001] This utility model relates to the field of woodworking machinery technology, specifically to a mortise and tenon joint insertion machine for picture frames. Background Technology

[0002] As a carrier and decorative component for exhibits such as paintings, calligraphy, and photographs, the structural stability and assembly precision of picture frames directly affect product quality. Mortise and tenon joints are the core technology for achieving stable assembly in picture frame manufacturing, which requires two key processes: mortise and tenon machining and milling.

[0003] In existing mortise and tenon joinery technology for picture frames, mortise and tenon milling require separate processing mechanisms: operators must first fix the picture frame profile onto the tooling table of the grooving mechanism, and then use the grooving tool assembly to create the groove; after the groove is finished, the profile must be manually removed from the grooving mechanism and transferred to the milling mechanism to remove excess profile from the mortise and tenon structure. This separate processing mode has drawbacks: the transfer of profile between the two mechanisms consumes a significant amount of manual time; the two independent mechanisms require separate drive systems and operating stations, increasing equipment purchase costs and workshop floor space, reducing overall processing efficiency, and making it difficult to meet the needs of mass production of picture frames. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a mortise and tenon insert machine for picture frames, which solves the technical problem in the prior art that the process of opening the mortise groove is separated from the process of milling the excess profiles on the mortise and tenon structure, resulting in low efficiency in picture frame production.

[0026] As a component for carrying and decorating exhibits such as paintings, calligraphy, and photographs, the structural stability and assembly precision of the picture frame 1 directly affect the product quality. The mortise and tenon joint is the core technology for achieving stable assembly in the production of the picture frame 1. There are many types of existing mortise and tenon structures, such as the mortise and tenon structure with a 45° bevel at the corner of a single piece of wood. However, the mortise and tenon structure adopted in this application is a mortise and tenon structure in which tenons 101 are made at the four corners of a rectangular frame and inserts inserts. This requires two key processes: processing the tenons 101 and milling the corners of the picture frame 1.

[0027] like Figures 1-6 As shown, it illustrates a mortise and tenon insert machine for a picture frame according to an embodiment of the present invention, used to open mortise grooves 101 at the corners of the picture frame 1. It includes a workbench 2, a grooving tool 211, and a milling part 221. The workbench 2 has a grooving station 21 and a milling station 22 on its surface. The grooving tool 211 is rotatably mounted on the grooving station 21. The milling part 221 is rotatably mounted on the milling station 22. After the insert is inserted into the mortise groove 101, the milling part 221 can mill off the part of the insert that protrudes from the side wall of the picture frame 1.

[0028] Specifically, the picture frame 1 is placed on the workbench 2. First, the corner of the picture frame 1 is aligned with the grooving tool 211 of the grooving station 21. The grooving tool 211 is rotated to create a tenon 101 at the corner of the picture frame 1. After the tenon 101 is processed, an insert is inserted into the tenon 101. Then, the corner of the picture frame 1 is moved to the milling station 22. The part of the insert protruding from the side wall of the picture frame 1 is milled off by the rotation of the milling part 221.

[0029] By integrating the grooving station 21 and the milling station 22 on the workbench 2, the processing of the tenon groove 101 of the picture frame 1 and the milling of the insert piece can be completed on the same equipment, eliminating the need to transfer the picture frame 1 between two independent mechanisms and reducing manual operation time; at the same time, there is no need to configure two independent drive systems and operating stations, reducing the workshop floor space, improving the overall processing efficiency of the picture frame 1, and making it more suitable for mass production needs.

[0030] It should be noted that there can be one, two, or three grooving tools 211, etc. The number of mortises 101 to be cut in the wood of the picture frame 1 to be processed is determined by placing the number of grooving tools 211 on the grooving station 21.

[0031] For example, such as Figure 1 As shown, in some examples, the frame tenon inserter also includes a driver 23 and a connecting rod 24; the driver 23 is disposed inside the worktable 2; one end of the connecting rod 24 is connected to the power output end of the driver 23, and the other end of the connecting rod 24 extends vertically through the table surface of the worktable 2 and is rotatably connected to the worktable 2; the grooving tool 211 is detachably disposed on the connecting rod 24; the driver 23 can drive the connecting rod 24 to rotate, so that the connecting rod 24 can drive the grooving tool 211 to rotate.

[0032] Specifically, power is provided by the driver 23 and transmitted to the grooving tool 211 via the connecting rod 24, enabling the grooving tool 211 to rotate. The rotational connection between the connecting rod 24 and the worktable 2 ensures the stability of power transmission, and the detachable design of the grooving tool 211 facilitates replacement according to processing requirements. The power of the driver 23 is transmitted through the connecting rod 24, driving the grooving tool 211 to rotate and create tenons 101 at the corners of the picture frame 1. When it is necessary to add or remove the grooving tool 211, it can be placed on the connecting rod 24.

[0033] The driver 23 and the connecting rod 24 provide stable power to the grooving tool 211, ensuring the continuity and reliability of the grooving process. The detachable design of the grooving tool 211 allows the equipment to adapt to the processing requirements of different numbers of tenons 101, improving the applicability of the equipment. At the same time, placing the driver 23 inside the worktable 2 makes the equipment structure more compact and reduces space occupation.

[0034] For example, such as Figure 2 As shown, in some examples, a through groove 201 is provided on the surface of the workbench 2, and the connecting rod 24 is disposed through the through groove 201, and the connecting rod 24 can slide horizontally along the through groove 201.

[0035] Specifically, the through groove 201 provides a path for the horizontal movement of the connecting rod 24. By sliding the connecting rod 24 along the through groove 201, the relative position of the grooving tool 211 and the corner of the picture frame 1 is adjusted to meet the processing requirements of picture frames 1 of different sizes. According to the position of the corner of the picture frame 1 and the position of the required tenon 101, the connecting rod 24 is pushed to slide along the through groove 201, so that the grooving tool 211 moves to the position corresponding to the corner of the picture frame 1, and then the grooving operation is performed.

[0036] The sliding engagement between the through groove 201 and the connecting rod 24 allows the position of the grooving tool 211 to be adjusted horizontally, which can adapt to the processing requirements of the tenon 101 of different sized picture frames 1 and improve the versatility of the equipment. The alignment of the grooving tool 211 and the picture frame 1 can be achieved through sliding adjustment, which is simple to operate, reduces the alignment time, and further improves the processing efficiency.

[0037] For example, such as Figure 2 As shown, in some examples, the picture frame tenon inserter also includes a slide rail 3 and a slide table 4; the slide rail 3 is disposed on the top surface of the worktable 2 and is arranged in a direction perpendicular to the through slide groove 201; the slide table 4 is slidably disposed on the slide rail 3 and is used to place the picture frame 1, and the slide table 4 can slide on the slide rail 3.

[0038] Specifically, the picture frame 1 is placed on the slide table 4. According to the grooving requirements, the slide table 4 is pushed to slide along the slide rail 3. At the same time, the connecting rod 24 is adjusted to slide along the through slide groove 201. When the corner of the picture frame 1 is aligned with the grooving tool 211, the driver 23 is turned on. The driver 23 drives the connecting rod 24 to rotate, so that the connecting rod 24 drives the grooving tool 211 to rotate and perform the grooving operation.

[0039] The slide rail 3 and slide table 4 provide a path for the movement and adjustment of the picture frame 1. Together with the sliding adjustment of the through groove 201 and the connecting rod 24, the relative position adjustment of the picture frame 1 and the grooving tool 211 in two vertical directions is realized, which improves the positioning accuracy of the mortise 101 machining. The slide table 4 is used to place the picture frame 1, so that the picture frame 1 can move with the slide table 4. The slide table 4 moves the picture frame 1 and moves in conjunction with the connecting rod 24 in the through groove 201, ensuring that the corners of the picture frame 1 are accurately aligned with the grooving tool 211.

[0040] For example, such as Figure 2 and Figure 4 As shown, in some examples, the frame tenon inserter also includes two positioning plates 41; both positioning plates 41 are set on the slide table 4, the two positioning plates 41 are arranged in a figure-eight shape and the two positioning plates 41 are perpendicular to each other, and an opening 4101 for accommodating the corner of the frame 1 is formed between the ends of the two positioning plates 41 near the grooving tool 211.

[0041] Specifically, the corners of the picture frame 1 are slid into the opening 4101 along the positioning plate 41. The two adjacent sides of the picture frame 1 are respectively attached to the two positioning plates 41 to achieve the positioning of the picture frame 1. Then, the slide table 4 is moved to align the picture frame 1 with the grooving tool 211. The mutually perpendicular positioning plates 41 limit the two adjacent sides of the picture frame 1. The figure-eight arrangement allows the corners of the picture frame 1 to slide into the opening 4101 along the positioning plate 41. The opening 4101 positions the corners of the picture frame 1, ensuring that the relative position of the corners of the picture frame 1 and the grooving tool 211 is fixed.

[0042] Two mutually perpendicular positioning plates 41 arranged in a V-shape accurately position the corners of the picture frame 1 through openings 4101. With manual clamping by the operator, this prevents the picture frame 1 from shifting during processing and ensures the accuracy of the tenon groove 101 opening position. The V-shape arrangement of the two positioning plates 41 facilitates the sliding of the corners of the picture frame 1 into the positioning position and allows the corners of the picture frame 1 to extend beyond the openings 4101, reducing positioning operation time and improving processing efficiency. The cooperation between the positioning plates 41 and the slide table 4 ensures that the picture frame 1 remains stable during movement and processing, further guaranteeing processing quality.

[0043] It should be noted that the positioning plate 41 is detachably mounted on the slide table 4 by bolts and nuts. The detachable mounting plate 41 facilitates subsequent maintenance or replacement.

[0044] For example, such as Figure 3 As shown, in some examples, the milling part 221 includes a mounting rod 2211 and a milling cutter 2212. The mounting rod 2211 is mounted on the worktable 2; the milling cutter 2212 is rotatably mounted on the mounting rod 2211. The milling cutter 2212 and the grooving cutter 211 are located on the same side of the slide table 4. The milling cutter 2212 is used to mill away the portion of the protruding side wall of the frame 1 of the insert inserted into the tenon 101. Specifically, after the frame 1 completes the tenon 101 machining and inserts the insert on the slide table 4, the operator places the frame 1 with the insert inserted on the milling station 22, and mills away the portion of the insert protruding from the side wall of the frame 1 by rotating the milling cutter 2212.

[0045] It should be noted that both the mounting rod 2211 and the connecting rod 24 are equipped with rotating rollers at one end inside the worktable 2 housing. The movable end of the driver 23 is fitted onto the rotating rollers via a belt, allowing the mounting rod 2211 and the connecting rod 24 to rotate synchronously, ensuring the compactness of the overall structure and the high efficiency of power transmission. This also avoids the problem of multiple drivers 23 occupying space inside the worktable 2 housing.

[0046] For example, such as Figure 3 As shown, in some examples, the milling part 221 also includes a lifting rod 2213. The lifting method of the lifting rod 2213 can be a manual adjustment of the lead screw, a motor-driven lead screw, or other methods that can achieve the lifting of the mounting rod 2211. Taking the manual adjustment of the lead screw as an example, the lead screw is set inside the worktable 2 and connected to the roller on the mounting rod 2211, which can drive the mounting rod 2211 to rise and fall.

[0047] Specifically, the bottom of the workbench 2 housing has a mounting hole, in which a nut compatible with the lead screw is fixed. The lead screw and nut are threaded together, and a wheel is installed at the end extending out from the bottom of the workbench 2 housing. The wheel has a handle, which the operator grasps and rotates to rotate the wheel, causing the lead screw to raise or lower the mounting rod 2211, ultimately adjusting the height of the milling cutter 2212. This allows the machine to adapt to the milling needs of picture frames 1 of different thicknesses or inserts of different protrusion heights. This improves the machine's adaptability to processing picture frames 1 of different specifications; the height adjustment function ensures that the milling cutter 2212 can accurately mill the excess part of the insert, avoiding over-milling or under-milling, and ensuring the processing quality of the picture frame 1.

[0048] It should be noted that a fixing plate is detachably installed on the worktable 2 near the milling cutter 2212. The fixing plate can position the picture frame 1 and the milling cutter 2212 so that the milling cutter 2212 is directly facing the side of the picture frame 1. Then, the operator pushes the picture frame 1 so that the side of the picture frame 1 contacts the milling cutter 2212 to mill off the excess insert portion protruding from the side of the picture frame 1. The relative fixation of the picture frame 1 by the fixing plate and the operator improves the milling accuracy of the side of the picture frame 1.

[0049] For example, such as Figure 1 and Figure 3 As shown, in some examples, the frame tenon and mortise inserter also includes a mounting frame 25, a lead screw 26, and a handwheel 27. The mounting frame 25 is slidably mounted on the inner wall of the worktable 2, and the driver 23 is mounted on the mounting frame 25. The lead screw 26 is mounted on the mounting frame 25. The handwheel 27 is mounted on the outer wall of the worktable 2, and a threaded hole is provided on the outer wall of the worktable 2. The lead screw 26 is threadedly connected to the threaded hole on the outer wall of the worktable 2, and the connecting rod 24 can move by rotating the handwheel 27. Specifically, rotating the handwheel 27 causes the lead screw 26 to push and pull the mounting frame 25 to slide under the action of the thread. The mounting frame 25 drives the driver 23, the connecting rod 24, and the grooving tool 211 to move synchronously until the grooving tool 211 reaches a position close to the corner of the frame 1. Then, rotating the handwheel 27 stops, and the grooving operation begins.

[0050] The mounting frame 25 provides a mounting carrier for the driver 23 and enables its sliding function; the lead screw 26 engages with the threaded hole on the outer wall of the worktable 2 to enable the grooving tool 211 to achieve position adjustment; the adjustment is carried out by the handwheel 27, which is simple and easy to operate, reducing the difficulty of operation; the overall structure realizes the control of the position of the grooving tool 211, improving the processing accuracy and operation convenience of the equipment.

[0051] For example, such as Figure 5 and Figure 6As shown, in some examples, the connecting rod 24 is also provided with several partition sleeves 28 and several clamping sleeves 29; two adjacent grooving tools 211 are separated by partition sleeves 28; the clamping sleeves 29 and partition sleeves 28 are detachably sleeved on the connecting rod 24, and the clamping sleeves 29 are located above the first grooving tool 211 and below the last grooving tool 211 on the connecting rod 24.

[0052] Specifically, the spacer sleeve 28 is used to maintain the distance between adjacent grooving tools 211, ensuring the positional accuracy when machining multiple tenons 101 simultaneously; the clamping sleeve 29 is detachably configured to axially clamp the grooving tool 211, preventing axial movement or loosening of the grooving tool 211 during rotation. When installing the grooving tool 211, the clamping sleeve 29, grooving tool 211, spacer sleeve 28, and grooving tool 211 are sequentially fitted onto the connecting rod 24, and finally the clamping sleeve 29 is fitted. The clamping sleeve 29 fixes all the grooving tools 211 and spacer sleeves 28 onto the connecting rod 24, ensuring stable rotation of the grooving tool 211.

[0053] The separator sleeve 28 ensures that the spacing between adjacent grooving tools 211 is consistent, ensuring that the positions of multiple mortises 101 processed simultaneously are accurate; the clamping sleeve 29 fixes the grooving tool 211 axially, preventing the grooving tool 211 from loosening or shifting during high-speed rotation, ensuring the stability and safety of the processing process; the detachable configuration of the separator sleeve 28 and the clamping sleeve 29 makes it easy to adjust the number and spacing of the grooving tools 211 according to processing requirements, improving the flexibility and applicability of the equipment.

[0054] It should be noted that the grooving tool 211 and the partition sleeve 28 can be increased or decreased according to the number of tenons 101 to be grooved, and the thickness of the partition sleeve 28 can be changed according to the width of the tenons 101 to be opened, so that the grooving station 21 can adapt to different picture frames 1.

[0055] For example, such as Figure 1 and Figure 5 As shown, in some examples, the bottom of the workbench 2 is provided with several rollers 5.

[0056] Rollers 5 provide support for the worktable 2 and convert the sliding friction between the worktable 2 and the ground into rolling friction, facilitating the movement of the worktable 2. When the position of the equipment needs to be adjusted, the worktable 2 is pushed, and the rollers 5 roll, driving the worktable 2 to move.

[0057] The rollers 5 enable the workbench 2 to move easily, allowing for adjustments to the equipment position based on workshop layout or production needs, thus improving equipment mobility; rolling friction reduces resistance during movement, lowers the operational difficulty of moving the equipment, and saves labor costs.

[0058] It should be noted that the bottom of the connecting rod 24 is equipped with a lifting rod 2213, which has the same structure as the mounting rod 2211, allowing the grooving tool 211 to be adjusted in height to accommodate different thicknesses of the picture frame 1 on the slide table 4. The grooving tool 211 moves horizontally and vertically along with the connecting rod 24, coordinating with the sliding of the slide table 4, thus achieving precise adjustment of the position of the grooving tool 211 relative to the picture frame 1.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
