Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of workpiece processing equipment, and more specifically, to an assembly fixture and workpiece processing equipment. Background Technology
[0002] Assembly fixtures, as key tools for ensuring the accuracy and efficiency of workpiece assembly, are widely used in various manufacturing fields. Traditional assembly fixtures typically use fixed guide pillars to position and guide the workpiece, which reveals many limitations in practical applications. On the one hand, fixed guide pillars cannot be flexibly adjusted according to different assembly processes or workpiece types. When loading, unloading, handling, or assembling workpieces in different positions, the fixed guide pillars obstruct the movement of the workpiece, affecting the convenience and smoothness of operation, and may even cause scratches or collision damage to the workpiece surface. On the other hand, due to the fixed nature of its structure, it is difficult to adapt to diverse assembly needs. When assembling workpieces of different sizes and shapes, frequent fixture changes are often required, increasing production costs and production cycles, and reducing production efficiency. Therefore, how to design an assembly fixture that can flexibly adjust the state of the guide pillars, improve the accuracy of workpiece positioning, and enhance the convenience of assembly operations has become an urgent technical problem to be solved in this field. Utility Model Content
[0003] The purpose of this utility model is to provide an assembly fixture and workpiece processing equipment to solve the technical problem of low workpiece assembly efficiency caused by the poor flexibility of the guide column of the assembly fixture in the prior art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] Firstly, an assembly fixture is provided, comprising:
[0006] The assembly plate, the guide seat disposed on the assembly plate, the first guide post axially connected to the guide seat, and the second guide post disposed on the assembly plate and opposite to the first guide post;
[0007] The guide seat is provided with a rotating shaft, and the first guide post is connected to the rotating shaft. The first guide post can rotate around the rotating shaft to switch between an upright state and a folded state. When the first guide post is in the upright state, it can be inserted into the guide hole corresponding to the workpiece. When the first guide post is in the folded state, it avoids the workpiece. The second guide post is in the upright state. The second guide post and the first guide post in the upright state are respectively inserted into the guide hole corresponding to the workpiece to guide the workpiece to be positioned at a preset position on the assembly plate.
[0008] By adopting the above technical solution, in terms of positioning accuracy, the dual-guide-post structure design, compared to the single-guide-post design, better constrains the workpiece's degrees of freedom, reduces positioning errors, and makes workpiece positioning more precise. This effectively improves the accuracy of assembled products and ensures product quality. Regarding ease of operation, the first guide post can be rotated to switch states, eliminating the need for cumbersome disassembly and installation of the guide post, greatly improving workpiece loading and unloading efficiency, saving operation time, and increasing production efficiency. In terms of space utilization, when the first guide post is in the collapsed state, it reduces the vertical space occupied by the fixture, making it particularly suitable for space-constrained working environments or automated production lines, thus improving space utilization. Furthermore, this fixture is suitable for various workpieces of different sizes but with similar guide hole structures, exhibiting strong versatility. This reduces the cost and time of designing and manufacturing dedicated fixtures for different workpieces, enhancing the fixture's applicability and flexibility.
[0009] In one embodiment, the guide seat is provided with a rotating shaft, the axis of which is perpendicular to the axis of the second guide post. The first guide post is connected to the rotating shaft and can rotate around the rotating shaft to switch between an upright state and a folded state.
[0010] In one embodiment, the guide seat includes a base and two oppositely arranged connecting ears. The base is disposed on the assembly plate and has a through hole. The two connecting ears are disposed on the base and a limiting groove communicating with the through hole is formed between them. The rotating shaft connects the two connecting ears and is perpendicular to the axis of the through hole. The first guide post includes a column and a connecting part connected to the column. The column is exposed outside the limiting groove. The connecting part has a waist-shaped groove. The rotating shaft passes through the waist-shaped groove and can move along the length of the groove. The connecting part is clearance-fitted with the through hole. The column can drive the connecting part to move upward to disengage from the through hole. The through hole no longer limits the connecting part, allowing the column to rotate around the rotating shaft to switch to a folded state. The column can drive the connecting part to insert into the through hole to switch to an upright state.
[0011] In one embodiment, the end of the column opposite to the connecting part is provided with a guide end, and the guide end has a chamfered structure.
[0012] In one embodiment, a damping element is provided between the guide seat and the first guide post, the damping element being used to provide resistance to maintain the guide post in an upright and collapsed state.
[0013] In one embodiment, the second guide post is fixedly disposed on the assembly plate.
[0014] In one embodiment, the first guide post and the second guide post are perpendicular to the assembly panel when they are in the upright state; the first guide post is parallel to the assembly panel when it is in the folded-down state.
[0015] In one embodiment, the assembly fixture further includes a plurality of limiting protrusions disposed on the assembly plate, the plurality of limiting protrusions surrounding to form a limiting structure for limiting the workpiece.
[0016] In one embodiment, the assembly fixture further includes a protective sleeve for fixing to the workpiece, the protective sleeve having a protective hole that communicates with the guide hole.

The specific implementation of this utility model is described in more detail below with reference to specific embodiments:
[0033] like Figure 1 and Figure 2 As shown, an assembly fixture provided in this embodiment of the present invention includes:
[0034] Assembly plate 1, guide seat 2 provided on assembly plate 1, first guide post 3 axially connected to guide seat 2, and second guide post 4 provided on assembly plate 1 and opposite to first guide post 3;
[0035] The guide seat 2 is provided with a rotating shaft 5. The first guide post 3 is connected to the rotating shaft 5. The first guide post 3 can rotate around the rotating shaft 5 to switch between an upright state and a folded state. When the first guide post 3 is in the upright state, it can be inserted into the guide hole 61 corresponding to the workpiece 6. When the first guide post 3 is in the folded state, it avoids the workpiece 6. The second guide post 4 is in the upright state. The second guide post 4 and the first guide post 3 in the upright state are respectively inserted into the guide hole 61 corresponding to the workpiece 6 to guide the workpiece 6 to be positioned at a preset position on the assembly plate 1.
[0036] Please refer to the following: Figure 3 and Figure 4 Specifically, the assembly fixture includes an assembly plate 1, a guide seat 2, a first guide post 3, and a second guide post 4.
[0037] The assembly plate 1 serves as the basic carrier of the entire fixture, providing an installation and support platform for other components, ensuring the relative positional accuracy of each component during operation and the stability of the overall structure.
[0038] The guide seat 2 is mounted on the assembly plate 1 and has a rotating shaft 5 inside. Its function is to provide a rotational connection point for the first guide post 3, ensuring that the first guide post 3 can rotate flexibly around the rotating shaft 5 and switch between different states. The first guide post 3 and the guide seat 2 are connected by the rotating shaft 5, and can switch between an upright state and a folded state. When upright, it can be accurately inserted into the guide hole 61 corresponding to the workpiece 6, and cooperate with the second guide post 4 to position the workpiece 6. When folded, it can avoid the workpiece 6, making it convenient to perform other operations on the workpiece 6.
[0039] The second guide post 4 is fixed on the assembly plate 1 and always remains upright. It works in conjunction with the first guide post 3, which is also upright, to insert into the guide holes 61 at both ends of the workpiece 6, thereby guiding the workpiece 6 to be accurately placed in the preset position of the assembly plate 1.
[0040] Please refer to the following: Figure 5 and Figure 6 During operation, when it is necessary to position and assemble workpiece 6, the first guide post 3 is first rotated to an upright position. At this time, the first guide post 3 and the always upright second guide post 4 are aligned with the corresponding guide holes 61 on workpiece 6 and inserted into them. Since the two guide posts are located at different positions on workpiece 6, their cooperation with the guide holes 61 can restrict the movement of workpiece 6 in the horizontal and vertical directions as well as its rotation around the axis, thereby achieving precise positioning of workpiece 6 and ensuring that workpiece 6 is in the preset position on the assembly plate 1, providing an accurate reference for subsequent assembly work.
[0041] When the assembly of workpiece 6 is completed or other operations such as replacement or adjustment of workpiece 6 are required, the first guide post 3 is disengaged from the guide hole 61 of workpiece 6, and then the first guide post 3 is rotated around the rotating shaft 5 to a lying position so that the operator can perform the corresponding operations on workpiece 6.
[0042] By adopting the above technical solutions, in terms of positioning accuracy, the dual-guide-post structure design, compared to the single-guide-post design, can better constrain the degrees of freedom of workpiece 6, reduce positioning errors, and make the positioning of workpiece 6 more precise. This effectively improves the accuracy of assembled products and ensures product quality. Regarding ease of operation, the first guide post 3 can rotate and switch states, eliminating the need for cumbersome disassembly and installation of guide posts, greatly improving the loading and unloading efficiency of workpiece 6, saving operation time, and increasing production efficiency. In terms of space utilization, when the first guide post 3 is in the collapsed state, it can reduce the space occupied by the fixture in the vertical direction, making it particularly suitable for space-constrained working environments or automated production lines, thus improving space utilization.
[0043] In one embodiment, the guide seat 2 is provided with a rotating shaft 5, the axis of the rotating shaft 5 is perpendicular to the axis of the second guide post 4, and the first guide post 3 is connected to the rotating shaft 5 and can rotate around the rotating shaft 5 to switch to an upright state or a folded state.
[0044] Specifically, the axis of the rotating shaft 5 of the guide seat 2 is perpendicular to the axis of the second guide post 4. The rotating shaft 5 and the second guide post 4 are perpendicular to each other. When the first guide post 3 is in the rotating switching state, it can accurately avoid the operating area of the workpiece 6. At the same time, in the upright positioning state, it cooperates with the second guide post 4 to form a stable and efficient positioning structure. This perpendicular relationship creates a spatial coordination, providing a solid foundation for the functional realization of the entire assembly fixture.
[0045] The first guide post 3 is connected to the rotating shaft 5 and can rotate around it. When assembling and positioning the workpiece 6, the operator rotates the first guide post 3 around the rotating shaft 5 to an upright position. Since the axis of the rotating shaft 5 is perpendicular to the axis of the second guide post 4, the first guide post 3, after being upright, can precisely cooperate with the second guide post 4 and be inserted into the corresponding guide holes 61 of the workpiece 6. The vertical axis relationship ensures that when the first guide post 3 is in upright positioning, it and the second guide post 4 form effective constraints on the workpiece 6 in different directions, restricting the movement of the workpiece 6 in multiple degrees of freedom, achieving precise two-dimensional positioning, and guiding the workpiece 6 to accurately fall into the preset position of the assembly plate 1. When other operations need to be performed on the workpiece 6, such as replacement or adjustment, the operator rotates the first guide post 3 around the rotating shaft 5 to a folded position. The vertical axis setting ensures that when the first guide post 3 is folded, it can avoid the workpiece 6 in the most reasonable path, without interfering with the workpiece 6 and the second guide post 4, freeing up sufficient space for subsequent operations.
[0046] Please refer to it again.Figure 3 and Figure 4 In one embodiment, the guide seat 2 includes a seat body 21 and two oppositely arranged connecting ears 22. The seat body 21 is disposed on the assembly plate 1 and has a through hole 23. The two connecting ears 22 are disposed on the seat body 21 and a limiting groove 24 communicating with the through hole 23 is formed between them. The rotating shaft 5 connects the two connecting ears 22 and is perpendicular to the axis of the through hole 23. The first guide post 3 includes a post body 31 and a connecting part 32 connected to the post body 31. The post body 31 is exposed outside the limiting groove 24. Outside of the groove 24, the connecting part 32 is provided with a waist-shaped groove 33. The rotating shaft 5 passes through the waist-shaped groove 33 and can move in the length direction of the groove 33. The connecting part 32 is clearance-fitted with the through hole 23. The column 31 can drive the connecting part 32 to move upward to disengage from the through hole 23. The through hole 23 no longer restricts the connecting part 32, so that the column 31 can rotate around the rotating shaft 5 to switch to the folded state. The column 31 can drive the connecting part 32 to be inserted into the through hole 23 to switch to the upright state.
[0047] Specifically, the guide seat 2 adopts a split structure, consisting of a seat body 21 and two oppositely arranged connecting ears 22. The seat body 21, as the basic load-bearing component, is fixedly installed on the assembly plate 1. The through hole 23 on it provides movement space and positioning reference for the connecting part 32 of the first guide post 3. The two connecting ears 22 are symmetrically arranged on the seat body 21, and the limiting groove 24 formed between them communicates with the through hole 23, providing an installation position for the rotating shaft 5 and limiting the range of motion of the first guide post 3. The rotating shaft 5 passes laterally through the two connecting ears 22 and is perpendicular to the axis of the through hole 23, forming the central axis of rotation of the first guide post 3.
[0048] The first guide post 3 consists of a post body 31 and a connecting part 32. The post body 31, which directly mates with the guide hole 61 of the workpiece 6, is exposed outside the limiting groove 24 and is used to position the workpiece 6. The connecting part 32 is provided with a waist-shaped groove 33, and the rotating shaft 5 passes through the waist-shaped groove 33, so that the connecting part 32 can move along the length of the waist-shaped groove 33. At the same time, the connecting part 32 and the through hole 23 adopt a clearance fit. This fit method not only ensures the degree of freedom of movement of the connecting part 32 in the through hole 23, but also achieves a certain degree of positioning when inserted into the through hole 23.
[0049] When positioning workpiece 6, the first guide post 3 is in an upright state. At this time, the connecting part 32 is inserted into the through hole 23. The limiting effect of the through hole 23 keeps the column 31 vertical. In cooperation with the second guide post 4, the workpiece 6 is accurately guided to the preset position of the assembly plate 1. When it is necessary to avoid workpiece 6 for other operations, the operator pulls the column 31 upward. The column 31 drives the connecting part 32 to disengage from the through hole 23. At this time, the connecting part 32 is no longer constrained by the through hole 23. Since the rotating shaft 5 passes through the waist-shaped groove 33 of the connecting part 32, and the connecting part 32 can move along the length of the waist-shaped groove 33, after the connecting part 32 disengages from the through hole 23, the operator can push the column 31 to make the connecting part 32 rotate around the rotating shaft 5, rotating the column 31 to a folded state, thus avoiding workpiece 6. When it is necessary to position the workpiece 6 again, rotate the fallen column 31 around the rotating shaft 5, and then move the column 31 downward so that the connecting part 32 is reinserted into the through hole 23. The column 31 returns to an upright state, and the positioning preparation is completed.
[0050] By adopting the above technical solution, in terms of positioning accuracy, the cooperation between the connecting part 32 and the through hole 23, as well as the coordinated work of the two guide posts, can accurately constrain the workpiece 6 and reduce positioning deviation. In terms of operational flexibility, the first guide post 3 can be switched between upright and inverted states through simple lifting, rotating, and inserting actions, thus improving operational efficiency.
[0051] In one embodiment, the end of the column 31 facing away from the connecting part 32 is provided with a guide end 34, and the guide end 34 has a chamfered structure.
[0052] Specifically, based on the column body 31 structure of the first guide post 3, a guide end 34 is added at the end opposite to the connecting part 32. This guide end 34 adopts a chamfered structure design. The chamfered structure refers to forming an inclined surface at a certain angle at the end of the column body 31, or a hemispherical shape. This structure is smoothly connected to the main body of the column body 31, and the end is specially treated without changing the main positioning function of the column body 31.
[0053] When positioning workpiece 6 using the assembly fixture, the guide end 34 of the first guide post 3 first contacts the guide hole 61 of workpiece 6. Because the guide end 34 has a chamfered structure, its inclined surface provides automatic centering guidance for the guide hole 61 of workpiece 6. When workpiece 6 approaches the first guide post 3, the chamfered slope "guides" the guide hole 61 into the post 31, allowing the post 31 to be inserted more smoothly into the guide hole 61, reducing positioning difficulties caused by collisions or jamming between the hole and the edge of the post 31 during insertion. Even if workpiece 6 has a certain angular deviation or positional offset during placement, the chamfered structure can still guide the post 31 smoothly into the guide hole 61 through its guiding characteristics, reducing the difficulty and operation time of manual precise alignment.
[0054] In one embodiment, a damping element is provided between the guide seat 2 and the first guide post 3, the damping element being used to provide resistance to maintain the guide post in an upright and collapsed state.
[0055] Specifically, in the assembly fixture, a damping element is added to the connection structure between the guide seat 2 and the first guide post 3. The damping element can be of various types, commonly including rubber damping pads, spring dampers, or hydraulic dampers. Its installation position is usually located at the contact or connection point between the guide seat 2 and the first guide post 3, such as between the rotating shaft 5 of the guide seat 2 and the connection part 32 of the first guide post 3, or in the area where relative movement may occur between the limiting groove 24 of the guide seat 2 and the column body 31 of the first guide post 3. One end of the damping element is firmly connected to the guide seat 2, while the other end forms a connection with the first guide post 3 that allows for relative movement but also provides resistance. For example, if a rubber damping pad is used, it can be glued to the guide seat 2 with strong adhesive. The first guide post 3 contacts the surface of the rubber damping pad, and the damping force is generated by the elastic deformation of the rubber. If a spring damper is used, one end of the spring can be fixed in a specific mounting hole in the guide seat 2, and the other end can be connected to the connecting part 32 of the first guide post 3 by means of a pin or the like, so that the spring will stretch and deform when the first guide post 3 rotates, thereby providing damping.
[0056] When the first guide post 3 is in an upright position for positioning the workpiece 6, the damping element maintains its upright position. At this time, the damping element generates a resistance in the opposite direction to that which might cause the first guide post 3 to deviate from its upright position due to external forces (such as slight collisions or vibrations during workpiece 6 placement). For example, if external vibrations cause the first guide post 3 to tend to tilt to one side, the damping element will generate a counterforce through its own deformation, preventing the first guide post 3 from tilting and ensuring it remains stably in an upright positioning state, allowing the workpiece 6 to be accurately positioned by the guide post. When it is necessary to switch the first guide post 3 to a collapsed position, the operator needs to apply an external force to overcome the resistance of the damping element to rotate the first guide post 3. As the first guide post 3 rotates, the damping element will deform accordingly, such as the rubber damping pad being squeezed, or the spring damper being compressed or stretched, continuously generating resistance to the rotation during this process. Until the first guide post 3 rotates to the folded state, the damping element will generate resistance to maintain its folded state, preventing the first guide post 3 from automatically returning to the upright state due to accidental vibration or slight external force, and ensuring that the first guide post 3 will not interfere with the operating space when performing other operations (such as loading, unloading, or adjusting workpiece 6).
[0057] In one embodiment, the second guide post 4 is fixedly mounted on the assembly plate 1.
[0058] Specifically, during the assembly fixture operation, the second guide post 4 remains fixed, serving as a reference point for positioning the workpiece 6. When the workpiece 6 is placed on the assembly plate 1, its guide hole 61 must be precisely aligned with and fitted into the second guide post 4. Since the second guide post 4 is fixed to the assembly plate 1, and the assembly plate 1 itself serves as the base platform of the fixture, providing stable support, the second guide post 4 remains stable during the positioning of the workpiece 6 and will not shift due to external forces. When engaged with the rotatable first guide post 3, the second guide post 4, as a fixed end, together with the upright first guide post 3, restricts the movement and rotation of the workpiece 6 in multiple degrees of freedom. For example, the horizontal left-right and forward-backward displacement of the workpiece 6, as well as its rotation around the vertical and horizontal axes, can all be constrained by the engagement of the two guide posts with the guide hole 61, thereby accurately fixing the workpiece 6 in the preset position of the assembly plate 1, providing a precise positioning basis for subsequent assembly processes.
[0059] In one embodiment, the first guide post 3 and the second guide post 4 are perpendicular to the assembly plate 1 when they are in an upright state; the first guide post 3 is parallel to the assembly plate 1 when it is in a collapsed state.
[0060] Specifically, the second guide post 4 is a fixed structure, always perpendicular to the assembly plate 1, and rigidly connected to the assembly plate 1 by means of threads, welding, or pins, forming a stable positioning reference. The first guide post 3 adopts a rotatable design, and is connected to the guide seat 2 via a rotating shaft 5. The guide seat 2 is fixed to the assembly plate 1. This connection method allows the first guide post 3 to switch between being vertical (upright state) and parallel (fallen state) to the assembly plate 1. To achieve stable rotation and precise positioning, the rotating shaft 5 of the first guide post 3 needs to be precisely installed to ensure that its rotation axis is parallel to the assembly plate 1, and that the post 31 itself is assembled perpendicular to the rotating shaft 5. Damping components, limiting structures, and other auxiliary components may also be provided between the post 31 and the guide seat 2 to ensure the stability and accuracy of state switching.
[0061] During the workpiece 6 positioning and assembly stage, both the first guide post 3 and the second guide post 4 are in an upright position and perpendicular to the assembly plate 1. At this time, the two fixed posts are like two vertical coordinate axes of a coordinate system, respectively inserted into the guide holes 61 corresponding to the workpiece 6, and precisely fix the workpiece 6 in the preset position of the assembly plate 1.
[0062] Please refer to it again. Figure 2 In one embodiment, the assembly fixture further includes a plurality of limiting protrusions 7 disposed on the assembly plate 1, the plurality of limiting protrusions 7 forming a limiting structure for limiting the workpiece 6.
[0063] Specifically, during the assembly of workpiece 6, the operator places workpiece 6 on the assembly plate 1. At this time, the limiting structure constructed by the limiting protrusions 7 begins to function, and the edge or specific part of workpiece 6 contacts and is blocked by the limiting protrusions 7. Since the limiting protrusions 7 enclose a closed or semi-closed limiting area, the horizontal movement of workpiece 6 is strictly limited within this area. For example, if the placement of workpiece 6 deviates and attempts to move beyond the enclosure of the limiting protrusions 7, the limiting protrusions 7 will physically block the workpiece 6 from moving further, prompting the operator to adjust the position of workpiece 6 in time until workpiece 6 accurately falls into the preset position defined by the limiting structure. When working in conjunction with the first guide post 3 and the second guide post 4, the limiting protrusions 7 first initially limit workpiece 6 to a general position range, reducing the randomness of workpiece 6 placement. Subsequently, the first and second guide posts 4 further precisely constrain the position of workpiece 6 by inserting into the guide holes 61 of workpiece 6, achieving omnidirectional precise positioning of workpiece 6 in three-dimensional space.
[0064] In one embodiment, the assembly fixture further includes a protective sleeve 62 for fixing on the workpiece 6, the protective sleeve 62 having a protective hole 63 that communicates with a guide hole 61.
[0065] Specifically, in the actual production process, when workpiece 6 is about to enter the assembly stage, the protective sleeve 62 must first be securely installed on workpiece 6. This installation process requires the protective sleeve 62 to fit tightly with workpiece 6, without any loosening or displacement, to ensure that the protective sleeve 62 can effectively fulfill its protective function. As workpiece 6, carrying the protective sleeve 62, is placed on the assembly plate 1, the protective hole 63 on the protective sleeve 62 immediately connects with the guide hole 61 of workpiece 6. At this time, the first guide post 3 and the second guide post 4 can be smoothly inserted into the protective hole 63 and the connected guide hole 61 in sequence.
[0066] Secondly, a workpiece processing device is provided, including a movable fixture and the aforementioned assembly fixture, wherein the movable fixture is used to transfer the workpiece 6 onto the assembly fixture.
[0067] By adopting the above technical solution, the workpiece processing equipment of this embodiment has the advantage of high processing efficiency, in addition to the advantages of the assembly fixture in the above embodiments.
[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
