Technical Field

[0001] This utility model relates to the field of furniture production technology, specifically a calibration tool for furniture production and processing. Background Technology

[0002] Furniture production encompasses six major steps: pattern making, material selection and cutting, woodworking, painting, upholstery, and assembly and packaging. Taking panel furniture as an example, its process includes raw material preparation, woodworking, painting, and packaging. After woodworking, a calibration tool is needed to calibrate its shape.

[0003] Some types of furniture boards require bending and shaping steps during processing, and the curvature of the boards needs to be standardized. During this process, calibration tools are needed to verify the curvature of the products.

[0004] In the existing technology, conventional tools for checking the curvature of boards are mostly fixed structures. Fixed tools cannot be adjusted according to the curvature of the board, and different sizes of calibration tools are required for calibration, which increases the cost of the device for checking the curvature of the board. Therefore, in order to solve the above problems, a calibration tool for furniture production and processing is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, conventional tools for verifying the curvature of boards are mostly fixed structures. Fixed verification tools cannot be adjusted according to the curvature of the board, requiring the preparation of calibration tools of different specifications for verification, which increases the cost of the device for verifying the curvature of the board. Therefore, a calibration tool for furniture production and processing is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The furniture production and processing calibration tool of this utility model includes a calibration tool base, with triangular brackets vertically fixed to both ends of the top surface of the calibration tool base, a U-shaped fixing frame provided above the calibration tool base, and mounting shafts symmetrically fixed to both sides of the U-shaped fixing frame. The mounting shafts are fitted into the circular openings of the triangular brackets. The adjacent side walls of the U-shaped fixing frame are symmetrically provided with board slots, and curved boards are fitted between two adjacent board slots. The bottom surface of the U-shaped fixing frame is fixed with multiple top rod guide sleeves, and calibration tool components are provided inside the multiple top rod guide sleeves.

[0007] Preferably, the calibration tool assembly includes a calibration tool top rod, one end of which is vertically fixed to a contact cylinder, which can contact the outer wall of the curved plate.

[0008] Preferably, the other end of the calibration tool top rod is fixedly connected to an inclined slider, and the adjacent sidewalls of two adjacent inclined sliders slide in contact.

[0009] Preferably, a limiting plate is vertically fixed to the lower side of one side of the U-shaped fixing frame, and multiple control slide plates are slidably installed on the inner wall of the opening of the limiting plate. One end of the control slide plate is fixed with an inclined contact block, and the inclined contact block contacts and slides with the inclined surface of the inclined slider one by one.

[0010] Preferably, a limiting pressure plate is vertically provided on the side wall of the limiting plate, and vertical guide rods are fixedly connected to the through holes at both ends of the limiting pressure plate. The vertical guide rods are fixedly connected to the side wall of the limiting plate through a bracket.

[0011] Preferably, the outer wall of the vertical guide rod is fitted with a spring, one end of which contacts the top surface of the limiting pressure plate, and the bottom surface of the limiting pressure plate is fixed with multiple limiting protrusions, which can respectively pass through the top circular holes of multiple control slide plates.

[0012] Preferably, a limiting sleeve is fixed at the center of the side wall of the triangular bracket, and the axis of the limiting sleeve is perpendicular to the horizontal plane.

[0013] Preferably, a limiting pin is fitted inside the through hole in the side wall of the mounting shaft, and one end of the limiting pin can be fitted inside the limiting sleeve.

[0014] The beneficial effects of this utility model are:

[0015] I. In this utility model, the calibration fixture assembly is installed by cooperating with the guide sleeve of the top rod of the U-shaped fixing frame and the limiting plate. The curvature of the curved plate is tested by the synchronous contact of the contact cylinders of multiple calibration fixture assemblies with the outer wall of the curved plate. The contact cylinders slide back and forth with the top rod of the calibration fixture under the restriction of the guide sleeve, which allows them to adjust their relative height within a certain range according to the curvature of the plate to be checked. This allows the device to check the curvature of the plate within a certain range, increasing the practicality of the device.

[0016] II. In this utility model, the installation of the calibration fixture base onto the U-shaped fixing frame is achieved through the mutual cooperation between the installation shaft and the triangular bracket. Before the extension height of the contact cylinder is fixed, the standard part of the curved plate is clamped between the appropriate plate slots. Then, the U-shaped fixing frame is rotated to the corresponding angle so that each contact cylinder is in contact with the curved plate. Then, the relative position of the control slide is fixed by the limiting pressure plate. At this time, the relative height of the contact cylinder is fixed. After the U-shaped fixing frame is rotated back, the contact cylinder can perform a standard curvature check on the curved plate. The process of rotating and displacing the contact cylinder is simple to operate and has high operating efficiency. Attached Figure Description

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figure 1 - Figure 5This utility model provides a calibration tool for furniture production and processing, including a calibration tool base 1. Triangular brackets 11 are vertically fixed to both ends of the top surface of the calibration tool base 1. A U-shaped fixing frame 2 is provided above the calibration tool base 1. Mounting shafts 21 are symmetrically fixed to both sides of the U-shaped fixing frame 2, and the mounting shafts 21 are fitted into the circular openings of the triangular brackets 11. Plate slots 22 are symmetrically opened between adjacent side walls of the U-shaped fixing frame 2, and curved plate 3 is fitted between two adjacent plate slots. Multiple top rod guide sleeves 23 are fixed to the bottom surface of the U-shaped fixing frame 2. Each of the multiple top rod guide sleeves 23 contains a calibration tool assembly 4. The calibration tool assembly 4 includes a calibration tool top rod 41. One end of the calibration tool top rod 41 is vertically fixed to a contact cylinder 411, which can contact the curved plate 3. The outer wall of the panel 3 contacts the U-shaped fixing frame 2 through the interlocking between the triangular bracket 11 and the mounting shaft 21. After the calibration rod 41 is fixed in a suitable position in the top rod guide sleeve 23, the curved panel 3, which is clamped between the panel slots 22, can contact the contact cylinders 411 at various positions. At this time, the curvature of the curved panel 3 meets the standard. When there are contact cylinders 411 that do not contact the curved panel 3, the curvature of the curved panel 3 does not meet the standard. Since the calibration rod 41 is slidably fitted inside the top rod guide sleeve 23, the device can calibrate the curved panel 3 with different curvatures by adjusting the relative height of the contact cylinders 411 before the calibration assembly 4 calibrates the curved panel 3.

[0028] like Figure 4 and Figure 5 As shown, the other end of the top rod 41 of the calibration fixture is fixedly connected to an inclined slider 412. The adjacent side walls of two adjacent inclined sliders 412 slide in contact. A limit plate 5 is vertically fixed to the lower side of one side of the U-shaped fixing frame 2. Multiple control slide plates 51 are slidably installed on the inner wall of the opening of the limit plate 5. An inclined contact block 511 is fixedly connected to one end of the control slide plate 51. The inclined contact block 511 slides in contact with the inclined surface of the inclined slider 412 one by one. The control slide plate 51 is slidably installed on the side wall of the U-shaped fixing frame 2 through the slot opened on the side of the limit plate 5, so that the control slide plate 51 can perform radial reciprocating motion under restriction. In the motion, the clamp at the bottom of the U-shaped fixing frame 2 limits the position of the inclined surface contact block 511 and the inclined surface slider 412 on both sides, so that the inclined surface slider 412 and the inclined surface contact block 511 can only perform relative radial movement. The control slide plate 51 contacts the inclined surface slider 412 at one end of the calibration tool top rod 41 through the inclined surface contact block 511. This allows the relative height of the contact cylinder 411 of the control slide plate 51 to change within a certain range during the sliding process. When the control slide plate 51 is fixed, the overall relative position of the calibration tool top rod 41 in the vertical state is fixed.

[0029] like Figure 1 and Figure 4As shown, a limiting plate 52 is vertically installed on the side wall of the limiting plate 5. Vertical guide rods 53 are fixedly connected to the through holes at both ends of the limiting plate 52. The vertical guide rods 53 are fixedly connected to the side wall of the limiting plate 5 through the bracket. A spring 54 is fitted on the outer wall of the vertical guide rod 53. One end of the spring 54 contacts the top surface of the limiting plate 52. Multiple limiting protrusions 521 are fixedly connected to the bottom surface of the limiting plate 52. The multiple limiting protrusions 521 can pass through the top circular holes of multiple control slide plates 51. The limiting plate 52 is installed with the cooperation of the vertical guide rods 53 and the spring 54. Under the elastic force of the spring 54, the limiting plate 52 and the limiting protrusions 521 as a whole have a downward elastic force. When the limiting protrusions 521 and the through holes of the control slide plates 51 are engaged with each other, the relative position of the control slide plates 51 is fixed, that is, the relative height of the contact cylinder 411 is fixed at this time.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, a limiting sleeve 12 is fixed at the center of the side wall of the triangular bracket 11. The axis of the limiting sleeve 12 is perpendicular to the horizontal plane. A limiting pin 6 is installed in the through hole of the side wall of the mounting shaft 21. One end of the limiting pin 6 can be locked inside the limiting sleeve 12. After the limiting pin 6 passes through the mounting shaft 21 and the limiting sleeve 12, the U-shaped fixing frame 2 cannot rotate as a whole. Before positioning the calibration fixture assembly 4, the limiting pin 6 needs to be removed, and the standard part of the curved plate 3 is locked between the appropriate plate slots 22. Then, the U-shaped fixing frame 2 is rotated to the corresponding angle so that each contact cylinder 411 is in contact with the curved plate 3. Then, the relative position of the control slide plate 51 is fixed by the limiting pressure plate 52. At this time, the relative height of the contact cylinder 411 is fixed. After the U-shaped fixing frame 2 is rotated back, the limiting pin 6 restores the rotation fixing effect on the mounting shaft 21. The contact cylinder 411 can be used to perform standard bending degree verification on the curved plate 3 with a different bending degree.

[0031] Working principle: The calibration fixture base 1 is installed on the U-shaped fixing frame 2 through the interlocking between the triangular bracket 11 and the mounting shaft 21. After the calibration fixture top rod 41 is fixed in a suitable position within the top rod guide sleeve 23, the curved plate 3, which is clamped between the plate slots 22, can contact the contact cylinders 411 at various positions. At this time, the curvature of the curved plate 3 meets the standard. When there are contact cylinders 411 that do not contact the curved plate 3, the curvature of the curved plate 3 does not meet the standard. Since the calibration fixture top rod 41 is slidably fitted inside the top rod guide sleeve 23, this allows the calibration fixture assembly 4 to check the curved plate 3 before the contact cylinders are checked. 411 The relative height adjustment allows the device to calibrate curved plate 3 with different curvatures. The control slide plate 51 is slidably installed on the side wall of the U-shaped fixing frame 2 through the slot on the side of the limiting plate 5, allowing the control slide plate 51 to perform radial reciprocating motion under restriction. The clamping plate at the bottom of the U-shaped fixing frame 2 limits the position by contacting the inclined contact blocks 511 and the inclined slider 412 on both sides, so that the inclined slider 412 and the inclined contact block 511 can only perform relative radial motion. The control slide plate 51 contacts the inclined slider 412 at one end of the calibration tool top rod 41 through the inclined contact block 511, which allows the control slide plate 51 to perform radial reciprocating motion under restriction. 1. During the sliding process, the relative height of the contact cylinder 411 can be changed within a certain range. When the control slide plate 51 is fixed, the relative position of the vertical calibration rod 41 is fixed. The limiting pressure plate 52 is installed with the cooperation of the vertical guide rod 53 and the spring 54. Under the elastic force of the spring 54, the limiting pressure plate 52 and the limiting protrusion 521 have a downward elastic force. When the limiting protrusion 521 and the through hole of the control slide plate 51 are engaged, the relative position of the control slide plate 51 is fixed, that is, the relative height of the contact cylinder 411 is fixed. The rotating shaft 21 and the limiting sleeve 12 are installed through the limiting pin 6. The U-shaped fixing frame 2 cannot rotate as a whole. Before positioning the calibration tool assembly 4, the limiting pin 6 needs to be removed, and the standard part of the curved plate 3 needs to be clamped between the appropriate plate slots 22. Then, rotate the U-shaped fixing frame 2 to the corresponding angle so that each contact cylinder 411 is in contact with the curved plate 3. Then, the relative position of the control slide plate 51 is fixed by the limiting pressure plate 52. At this time, the relative height of the contact cylinder 411 is fixed. After the U-shaped fixing frame 2 rotates back to its original position, the limiting pin 6 restores the rotation fixing effect on the mounting shaft 21. The contact cylinder 411 can then be used to perform standard bending degree verification on the curved plate 3 with a different bending degree.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
