Description

Technical Field

[0001] This application relates to the technical field of tooling fixtures, and particularly to a tooling with adjustable inclination angle. Background Art

[0002] Products often need to go through multiple processing procedures on the production line. In order to improve the positional accuracy of products during production and assembly, tooling fixtures are generally set on the production line to support and position workpieces. For electronic products such as mobile phones, earphones, and computers, they are usually assembled from multiple components, and multiple procedures are required when assembling multiple components together. Different procedures have different requirements for the inclination angle of product placement. Existing tooling fixtures generally do not have the function of inclination angle adjustment, and their versatility is poor. The same workpiece needs to be replaced with tooling fixtures multiple times during the assembly process, resulting in low assembly efficiency and high tooling fixture costs; while some tooling fixtures with the function of inclination angle adjustment have relatively complex adjustment and limit structures, which are inconvenient to use, and the inclination angle adjustment steps are large, making it difficult to accurately adjust to the required inclination angle. Utility Model Content

[0003] In order to solve the above problems, this application provides a tooling with adjustable inclination angle, which is ingeniously designed and has a simple structure. The inclination angle of the fixed plate of this application is adjustable, making this tooling have good versatility. The technical solutions adopted in this application are as follows:

[0004] A tooling with adjustable inclination angle, comprising:

[0005] A base, on which a driving component is installed; a fixed plate, which is rotatably connected to the base; a rotating pair, the rotating pair includes a first rotating member and a second rotating member, the first rotating member is hinged to the second rotating member, the axis of rotation of the fixed plate and the base is parallel to the axis of the rotating pair, the first rotating member is slidably connected to the fixed plate and the sliding direction is perpendicular to the axis of the rotating pair, the second rotating member is connected to the driving component, and the driving component can drive the second rotating member to reciprocate in a direction perpendicular to the axis of the rotating pair; when the second rotating member gradually approaches the rotation connection of the fixed plate and the base, the inclination angle of the fixed plate relative to the base gradually increases; and when the second rotating member gradually moves away from the rotation connection of the fixed plate and the base, the inclination angle of the fixed plate relative to the base gradually decreases.

[0006] In this application, the inclination angle of the fixed plate relative to the base can be adjusted, so that this tooling can be applied to a variety of processes with different requirements for the inclination angle, avoiding the situation of making a variety of toolings with fixed inclination angles to meet the different requirements for the inclination angle in different processes. The tooling of this application has good versatility, can save the costs generated by making a variety of toolings with fixed inclination angles, and at the same time, when the inclination angle requirement changes, only the inclination angle of the fixed plate in the tooling needs to be adjusted adaptively, without disassembling and replacing the tooling, saving the process of tooling disassembly and replacement, and greatly improving the production and assembly efficiency of products.

[0007] In some embodiments, the driving assembly includes a motor and a lead screw pair. The motor is used to drive the rotation of the lead screw in the lead screw pair. The axis of the lead screw is perpendicular to the axis of the rotating pair. The second rotating member is fixed on the nut of the lead screw pair.

[0008] In some embodiments, a slide rail is fixed to the bottom side of the fixed plate. The first rotating member is provided with a chute. The slide rail is clamped in the chute and is in sliding cooperation with the chute. The sliding connection between the first rotating member and the fixed plate is realized through the sliding cooperation between the slide rail and the chute.

[0009] Through the clamping of the slide rail and the chute, the slide rail can be prevented from disengaging from the chute, ensuring the smooth sliding of the slide rail relative to the chute.

[0010] In some embodiments, clamping grooves are provided on both side surfaces of the slide rail, and protrusions are provided on the side wall of the chute. The protrusions are clamped in the clamping grooves to realize the clamping of the slide rail and the chute.

[0011] In some embodiments, the first rotating member and the second rotating member are hinged through a pin shaft passing through both of them, and both ends of the pin shaft are exposed outside the first rotating member and the second rotating member. Support wheels are provided at the exposed ends of the pin shaft, and the wheel surfaces of the support wheels abut against the bottom surface of the fixed plate.

[0012] By providing support wheels at both ends of the pin shaft, on the one hand, the support wheels can share the pressure of the slide rail on the chute, reduce the frictional resistance when the slide rail slides relative to the chute, and improve the smoothness when the slide rail slides relative to the chute. On the other hand, the existence of the support wheels can provide stable support for the fixed plate, improve the stability of the fixed plate, and prevent the fixed plate from tilting accidentally.

[0013] In some embodiments, a mounting seat is fixed on the base. The mounting seat is provided with a plane; the fixed plate is hinged to the mounting seat to realize the rotational connection between the fixed plate and the base; the plane is perpendicular to the axis of the rotational connection between the fixed plate and the base, and inclination scales are provided on the plane.

[0014] By setting an inclination scale on the plane of the mounting base, a comparison reference or a verification reference can be provided for the inclination angle of the fixing plate, so that relevant personnel can determine whether the fixing plate rotates in place.

[0015] In some embodiments, the fixing plate is provided with fixing holes for mounting a jig.

[0016] By setting the fixing holes, the jig can be firmly mounted on the fixing plate, ensuring the connection stability between the jig and the fixing plate.

[0017] In some embodiments, a position sensing device is further included, and the position sensing device is used to sense the position of the second rotating member.

[0018] By setting the position sensing device, the position information of the second rotating member can be obtained, and then the driving assembly can be controlled according to the position information of the second rotating member to drive the second rotating member to continue to move or stop moving, so that the second rotating member can be restricted to slide within a certain range and prevent the second rotating member from exceeding the stroke range.

[0019] In some embodiments, the position sensing device is an infrared sensor, and the infrared direction of the infrared sensor is parallel to the moving direction of the second rotating member.

[0020] By setting the infrared sensor and the infrared direction of the infrared sensor being parallel to the moving direction of the second rotating member, the position information of the second rotating member can be obtained in real time. On the one hand, it can prevent the second rotating member from exceeding the stroke range. On the other hand, since the position information of the second rotating member corresponds one-to-one with the inclination data of the fixing plate, the inclination data of the fixing plate can be obtained in real time according to the corresponding relationship between the position of the second rotating member and the inclination of the fixing plate.

[0021] In some embodiments, the motor is a stepper motor.

[0022] By selecting a stepper motor, the control accuracy of the inclination angle of the fixing plate can be ensured. The control system of the stepper motor is relatively simple, while the control system of the servo motor is more complex, and the purchase cost of the stepper motor is also lower than that of the servo motor.

Obviously, the drawings in the following description are only some embodiments of the present application. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings, and other embodiments can also be obtained.

[0043] It should also be further understood that the term "and / or" used in the description of the present application and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0044] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "install", "connect", and "couple" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0045] In addition, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0046] Referring to Figures 1-4 , the present application provides a tooling with adjustable inclination angle, including: a base 1, a fixing plate 2 and a rotating pair; a driving component is installed on the base 1; the fixing plate 2 is rotatably connected to the base 1; the rotating pair includes a first rotating member 3 and a second rotating member 4, the first rotating member 3 is hinged to the second rotating member 4, the axis of rotation of the fixing plate 2 and the base 1 is parallel to the axis of the rotating pair, the first rotating member 3 is slidably connected to the fixing plate 2 and the sliding direction is perpendicular to the axis of the rotating pair, the second rotating member 4 is connected to the driving component, and the driving component can drive the second rotating member 4 to reciprocate in a direction perpendicular to the axis of the rotating pair; when the second rotating member 4 gradually approaches the rotation connection of the fixing plate 2 and the base 1, the inclination angle of the fixing plate 2 relative to the base 1 gradually increases; and when the second rotating member 4 gradually moves away from the rotation connection of the fixing plate 2 and the base 1, the inclination angle of the fixing plate 2 relative to the base 1 gradually decreases.

[0047] It can be understood that the main function of the driving component is to drive the reciprocating motion of the second rotating member 4. The driving component can be a telescopic cylinder or a telescopic hydraulic cylinder, or an electric cylinder. Taking the electric cylinder as an example, the second rotating member 4 is connected to the telescopic rod of the electric rod. Through the telescopic motion of the telescopic rod in the main body of the electric cylinder, the reciprocating movement of the second rotating member 4 is realized. It should be noted that after the second rotating member 4 is connected to the telescopic rod, the telescopic rod will be subjected to a force perpendicular to its own length direction. In order to prevent the telescopic rod from bending and to ensure the free telescopic motion of the telescopic rod, the telescopic rod needs to be supported, and the support of the telescopic rod cannot affect its free telescopic motion. Refer to Figures 1-4 , in one embodiment, the driving component includes a motor 5 and a lead screw pair. The motor 5 is used to drive the rotation of the lead screw shaft 6 in the lead screw pair. The lead screw shaft 6 is perpendicular to the axis of the rotating pair. The second rotating member 4 is fixed on the nut 7 in the lead screw pair. The motor 5 can specifically be a stepper motor or a servo motor, preferably a stepper motor, which can not only ensure the control accuracy of the inclination angle of the fixed plate 2, but also save the purchase cost of the motor 5.

[0048] It can be understood that there are various connection methods between the output end of the motor 5 and the lead screw shaft 6, such as welding, screwing or clamping. Preferably, it is connected through a coupling. The coupling can adapt to the situation where the output end of the motor 5 and the lead screw shaft 6 are not coaxial. It should be noted that in one embodiment, in order to improve the bearing capacity of the lead screw shaft 6 (the force perpendicular to the length direction of the lead screw shaft 6), a support seat is provided at one end of the lead screw shaft 6 away from the motor 5.

[0049] It is easily understood that the inclination angle of the fixed plate 2 relative to the base 1 in the present application can be adjusted, so that the present tooling can be applicable to various processes with different requirements for the inclination angle, avoiding the situation that in order to meet the different requirements for the inclination angle in different processes, it is necessary to manufacture multiple toolings with fixed inclination angles. The tooling of the present application has good versatility, can save the costs generated by manufacturing multiple toolings with fixed inclination angles, and at the same time, when the inclination angle requirement changes, only the inclination angle of the fixed plate 2 in the tooling needs to be adjusted adaptively, without disassembling and replacing the tooling, saving the procedure of tooling disassembly and replacement, and greatly improving the production and assembly efficiency of the product.

The slide rail 8 is clamped in the chute 9 and slidably cooperates with the chute 9. Through the sliding cooperation between the slide rail 8 and the chute 9, the sliding connection between the first rotating member 3 and the fixed plate 2 is realized. Through the clamping of the slide rail 8 and the chute 9, it can be prevented that the slide rail 8 disengages from the chute 9, ensuring the smooth sliding of the slide rail 8 relative to the chute 9.

[0051] In this embodiment, clamping grooves 10 are provided on both side surfaces of the sliding rail 8, and protrusions 11 are provided on the side wall of the sliding groove 9. The protrusions 11 are clamped in the clamping grooves 10 to achieve the clamping connection between the sliding rail 8 and the sliding groove 9. In other embodiments, it is also possible that protrusions 11 are provided on both side surfaces of the sliding rail 8, and clamping grooves 10 are provided on the side wall of the sliding groove 9.

[0052] Refer to Figure 1 , Figure 2 , Figure 4 , in one embodiment, the first rotating member 3 and the second rotating member 4 are hinged by a pin shaft 12 passing through both of them, and both ends of the pin shaft 12 are exposed outside the first rotating member 3 and the second rotating member 4. Support wheels 13 are provided at the exposed ends of the pin shaft 12, and the wheel surfaces of the support wheels 13 abut against the bottom surface of the fixing plate 2. It is easy to understand that by providing the support wheels 13 at both ends of the pin shaft 12, on the one hand, the support wheels 13 can share the pressure of the sliding rail 8 on the sliding groove 9, reduce the frictional resistance when the sliding rail 8 slides relative to the sliding groove 9, and improve the smoothness when the sliding rail 8 slides relative to the sliding groove 9. On the other hand, the presence of the support wheels 13 can provide stable support for the fixing plate 2, improve the stability of the fixing plate 2, and prevent the fixing plate 2 from tilting accidentally.

[0053] It should be noted that refer to Figures 1-4 , in one embodiment, a mounting seat 14 is fixed on the base 1, and the mounting seat 14 is provided with a plane 15; the fixing plate 2 is hinged to the mounting seat 14 to achieve the rotational connection between the fixing plate 2 and the base 1; the plane 15 is perpendicular to the axis of the rotational connection between the fixing plate 2 and the base 1, and an inclination scale (not shown in the figure) is provided on the plane 15.

By providing the fixing holes 16, the clamping fixture can be firmly installed on the fixing plate 2, ensuring the connection stability between the clamping fixture and the fixing plate 2.

[0055] In one embodiment, the tooling further includes a position sensing device for sensing the position of the second rotating member 4. Specifically, the position sensing device can be a ranging sensor or a proximity switch, etc. By providing the position sensing device, the position information of the second rotating member 4 can be obtained, and then according to the position information of the second rotating member 4, the driving assembly can be controlled to drive the second rotating member 4 to continue to move or stop moving, so that the second rotating member 4 can be restricted to slide within a certain range and prevent the second rotating member 4 from exceeding the stroke range.

[0056] In one embodiment, the position sensing device is selected as an infrared sensor in the type of range sensor, and the infrared ray direction of the infrared sensor is parallel to the moving direction of the second rotating member 4. By providing the infrared sensor and making the infrared ray direction of the infrared sensor parallel to the moving direction of the second rotating member 4, the position information of the second rotating member 4 can be obtained in real time. On the one hand, it can prevent the second rotating member 4 from exceeding the stroke range. On the other hand, since the position information of the second rotating member 4 corresponds one-to-one with the inclination data of the fixed plate 2, the inclination data of the fixed plate 2 can be obtained in real time according to the corresponding relationship between the position of the second rotating member 4 and the inclination of the fixed plate 2.

[0057] It should be noted that the above embodiments can be freely combined as needed. The above is only the preferred embodiment of the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present application.
