Description

Technical Field

[0001] This utility model relates to the field of assembly tooling technology, and in particular to a fastener assembly tooling for plastic boxes. Background Technology

[0002] Plastic crates are widely used in warehousing, logistics and daily necessities due to their lightweight and durable properties. Many plastic crates are equipped with buckles for locking and securing the lid.

[0003] In the production process of plastic boxes, the assembly of buckles is an important step. At present, the installation of buckles mostly relies on manual operation or simple auxiliary tools, such as placing the buckle in the reserved slot position of the plastic box, and then pressing it in and fixing it by tapping or using a simple presser.

[0004] This assembly method has obvious shortcomings. Manual operation is inefficient and labor-intensive, and the assembly quality is difficult to guarantee. When pressing the buckles, the plastic box needs to be effectively fixed to resist the impact or pressure generated during pressing. Existing assembly methods or simple tooling often lack precise positioning and stable clamping structures for the plastic box. The plastic box is prone to shaking, slipping or shifting during the pressing process. This causes the buckles to fail to be pressed accurately into the preset slots, which can easily lead to installation tilt, incomplete assembly or damage to the box slots, affecting the product qualification rate and assembly consistency.

[0005] Therefore, this utility model proposes a snap-on assembly fixture for plastic boxes to address the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing technology of plastic box fastener assembly tooling, such as the lack of precise positioning and stable clamping of plastic boxes, which leads to easy displacement of the box body during the pressing process, low assembly accuracy and poor consistency, this utility model aims to provide a plastic box fastener assembly tooling with improved structure that can effectively solve the above problems.

[0007] This utility model provides a fastener assembly fixture for plastic boxes, including a workbench and a positioning seat fixed on the workbench. The positioning seat is used to initially limit the plastic box. The fixture also includes an assembly component and a fixing component.

[0008] The assembly component includes an L-shaped upright plate fixed to the worktable, which provides support for the pressing cylinder. The pressing cylinder is fixed to the L-shaped upright plate, and the piston rod of the pressing cylinder serves as a pressure rod. The axis of motion of the pressure rod is perpendicular to the worktable, and the pressure rod is positioned vertically above the positioning seat to ensure accurate pressing position.

[0009] Furthermore, the fixing component includes a connecting block fixed to the worktable, which serves as the base of the fixing component. The fixing component also includes a handle, a connecting rod, and an extrusion column. The handle is rotatably connected to the extrusion column, one end of the connecting rod is rotatably connected to the handle, the extrusion column is slidably mounted on the limiting block, and the tail end of the extrusion column is rotatably connected to the other end of the connecting rod, forming a connecting rod drive mechanism.

[0010] Preferably, the assembly assembly further includes a controller electrically connected to the pressing cylinder for driving the pressing cylinder to work and realize automated control of the pressing action.

[0011] Preferably, the tooling also includes a support frame, on which the workbench is fixedly mounted to provide a stable load-bearing foundation for the entire tooling.

[0012] Preferably, the fixing component further includes a limiting block, which is fixed to the connecting block and provides one-sided guidance for the sliding of the extrusion column.

[0013] Preferably, as a further provision, the fixing component also includes a fixing block fixed to the connecting block, which provides guidance on the other side for the sliding of the extrusion column.

[0014] Preferably, the extrusion column is located between the limiting block and the fixing block, and its linear movement is ensured by the constraints on both sides to prevent deflection when subjected to force.

[0015] Preferably, as a more specific sliding fit method, the two sides of the extrusion column are slidably connected to the inner wall of the limiting block and the inner wall of the fixing block, respectively, which increases the contact area and makes the extrusion column more stable when pushed by force.

[0016] Preferably, the handle is rotatably connected to the connecting block via a pivot, which provides a stable and reliable pivot point, making the handle pressing operation smoother.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting up an assembly component, a positioning seat, and a fixing component, wherein the assembly component drives a pressure rod to press the plastic box through a pressing cylinder, the positioning seat is used to initially position the plastic box, and the fixing component clamps and fixes the plastic box before pressing through a linkage structure of a handle, a connecting rod, and a pressing column, solves the problems of inaccurate positioning, unstable clamping, and easy displacement during pressing that lead to low assembly accuracy in the prior art, and achieves the technical effects of accurate positioning, reliable fixing, and stable pressing.

[0018] 2. This utility model, by setting a fixing assembly consisting of a handle, a connecting rod and a pressing column, uses a connecting rod mechanism to convert the force of pressing the handle into the horizontal thrust of the pressing column, thereby realizing the quick manual clamping of the plastic box. This solves the problems of high labor intensity and poor fixing effect of manually supporting the box, and achieves the technical effects of convenient operation, stable and reliable clamping, and prevention of damage to the box during pressing.

[0019] 3. This utility model uses a pressing cylinder to drive a pressure rod to automatically press the buckle, replacing manual hammering or pressing with uniform and controllable pneumatic pressure. This solves the problems of uneven force, easy damage to the box or buckle, and poor assembly consistency in the prior art, and achieves the technical effects of improving assembly efficiency, ensuring consistent assembly quality, and reducing manual labor intensity.

[0022] Please refer to Figures 1 to 4 This utility model provides a buckle assembly fixture for plastic boxes, which aims to solve the problems in the prior art where inaccurate positioning and unstable clamping of plastic boxes lead to easy displacement of the box body during the pressing process, affecting assembly efficiency and consistency.

[0023] like Figure 1 As shown, the plastic box assembly fixture includes a bracket 101 and a worktable 102 fixedly mounted on the bracket 101. A positioning seat 104 is fixed on the worktable 102. Figure 1 and Figure 3As shown, the tooling also includes an assembly assembly 1, which includes an L-shaped vertical plate 107 fixed to the worktable 102. A pressing cylinder 103 is fixed on the L-shaped vertical plate 107, and the piston rod of the pressing cylinder 103 serves as a pressure rod 106. The pressure rod 106 is located vertically above the positioning seat 104, as shown. Figure 1 and Figure 4 As shown, the tooling also includes a fixing component 2, which includes a connecting block 201 fixed to the worktable 102, a handle 205 rotatably connected to the extrusion column 203, one end of a connecting rod 206 rotatably connected to the handle 205, the extrusion column 203 slidably installed in the limiting block 202, and the tail of the extrusion column 203 rotatably connected to the other end of the connecting rod 206.

[0024] Please refer to Figure 1 and Figure 3 Assembly component 1 is used to perform the pressing action of the fastener. Assembly component 1 includes an L-shaped upright plate 107, which is fixed to the worktable 102 and provides a mounting base for the pressing cylinder 103. The pressing cylinder 103 is fixed to the horizontal cantilever part of the L-shaped upright plate 107. The piston rod of the pressing cylinder 103 is the pressing rod 106. The axis of the pressing rod 106 is set perpendicular to the worktable 102. The lower end of the pressing rod 106 is directly opposite the positioning seat 104, thereby ensuring the accuracy of the pressing position. Assembly component 1 also includes a controller 105, which is electrically connected to the pressing cylinder 103 to control the starting and resetting of the pressing cylinder 103.

[0025] Please refer to the following carefully. Figure 1 and Figure 4 The structure of the fixing component 2 is described in detail below. The fixing component 2 is used to clamp and fix the plastic box before pressing. The fixing component 2 includes a connecting block 201, which is fixed to the worktable 102 as the mounting base of the fixing component 2. The fixing component 2 also includes a limiting block 202 and a fixing block 204. The limiting block 202 is fixed to the connecting block 201, and the fixing block 204 is also fixed to the connecting block 201. The extrusion column 203 is located between the limiting block 202 and the fixing block 204, and the two sides of the extrusion column 203 are slidably connected to the inner wall of the limiting block 202 and the inner wall of the fixing block 204, respectively. This sliding fit structure ensures that the extrusion column 203 reciprocates stably in the horizontal direction.

[0026] The driving mechanism of the fixed component 2 includes a handle 205 and a connecting rod 206. The handle 205 is rotatably connected to the extrusion column 203 via a rotating shaft. One end of the connecting rod 206 is rotatably connected to the handle 205, and the other end of the connecting rod 206 is rotatably connected to the inner wall of the extrusion fixing block 204. When the handle 205 is pressed down, the handle 205 rotates around its rotating shaft, driving the connecting rod 206 to move. The connecting rod 206 converts the pressing force into a horizontal thrust and transmits it to the extrusion column 203, causing the extrusion column 203 to slide forward along the inner wall of the limiting block 202 and the fixing block 204.

[0027] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, please refer to Figure 1 To facilitate control of the pressing action, the assembly assembly 1 also includes a controller 105, which is electrically connected to the pressing cylinder 103.

[0028] As a preferred embodiment, please refer to Figure 1 In order to improve the structural stability of the entire device, the tooling also includes a support 101, and the worktable 102 is fixedly installed on the top of the support 101.

[0029] As a preferred embodiment of the fixing component 2, please refer to Figure 4 To guide and limit the movement of the extrusion column 203, the fixing assembly 2 also includes a limiting block 202, which is fixed to the connecting block 201. Please refer to... Figure 4 The fixing component 2 also includes a fixing block 204, which is also fixed on the connecting block 201. The fixing block 204 and the limiting block 202 are arranged at intervals relative to each other, and the main body of the extrusion column 203 is arranged between the limiting block 202 and the fixing block 204.

[0030] Specifically, to ensure the smooth movement of the extrusion column 203, both sides of the extrusion column 203 are slidably connected to the inner walls of the limiting block 202 and the fixing block 204, respectively. For a specific explanation of the connection method of handle 205, please refer to Figure 4 The handle 205 is rotatably connected to the connecting block 201 via a rotating shaft.

[0031] The working principle of this new type of plastic box fastener assembly fixture is as follows: When the snap-on installation is required, first place the plastic box on the workbench 102 and push the plastic box toward the positioning seat 104. The positioning seat 104 limits the end of the plastic box so that the snap-on installation area of ​​the box body is accurately aligned with the vertical lower part of the pressure rod 106. Before pressing, the operator presses the handle 205 of the fixing component 2. The handle 205 rotates around its pivot and converts the action into a horizontal thrust through the connecting rod 206, driving the extrusion column 203. The extrusion column 203 slides stably between the inner wall of the limiting block 202 and the fixing block 204. The extrusion column 203 moves forward and closely abuts against the side wall of the plastic box, thereby firmly fixing the plastic box on the workbench 102 and the positioning seat 104.

[0032] After the plastic box is clamped, the operator starts the controller 105. The controller 105 is electrically connected to and drives the pressing cylinder 103 to work. The pressing cylinder 103 drives its piston rod, i.e. the pressure rod 106, to move downwards in sync. The pressure rod 106 applies stable pressure to the buckle position on the plastic box, pressing the buckle into the reserved slot of the plastic box. After the pressing is completed, the pressing cylinder 103 resets, the pressure rod 106 rises back to the initial position, the operator releases the handle 205, the connecting rod 206 drives the extrusion column 203 to retract, releasing the fixation of the plastic box and completing one assembly cycle.

[0033] Through the coordinated operation of assembly component 1, positioning seat 104 and fixing component 2, the initial positional accuracy of the plastic box is first ensured by positioning seat 104. Then, the manual linkage 206 structure and extrusion column 203 of fixing component 2 provide a stable and reliable clamping force, effectively preventing the plastic box from shaking and shifting during the subsequent pressing process. Finally, the pressing cylinder 103 and pressure rod 106 provide a uniform pressing force. This utility model solves the problems of low assembly accuracy and poor efficiency caused by inaccurate positioning and unstable clamping in the prior art by using this combination of positioning, clamping and pressing structure.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
