Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, specifically a mechanical parts fixing device. Background Technology

[0002] With the rapid development of industry, manufacturing has entered a stage of large-scale production. Whether it's automobiles, electronic equipment, or other mechanical products, there's a need to produce large quantities of goods in a short period. This requires efficient and stable component fixing devices that can quickly and accurately secure components to adapt to the rhythm of assembly line production.

[0003] Currently, in existing technologies, if the fixing device cannot be flexibly adjusted for mechanical parts of different sizes, it is necessary to prepare a dedicated fixing device for each size of part, which increases equipment and storage costs. In view of this, we propose a fixing device for mechanical parts. Utility Model Content

[0004] The main objective of this invention is to provide a mechanical parts fixing device that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a mechanical component fixing device, comprising a base, a fixing frame fixedly connected to the outer wall of the base, a pressing component provided on the fixing frame, a fixing shell fixedly connected to the outer wall of the base, the fixing shell limiting the component body through the fixing device, and an elastic limiting component provided on the fixing device. The fixing device includes:

[0006] The outer wall of the fixed shell is provided with a clearance groove, and a hydraulic cylinder is provided in the inner cavity of the fixed shell. The output end of the hydraulic cylinder is fixedly connected to the hinge block.

[0007] Hinged plate one, the hinge block is hinged to hinged plate one, hinged plate one is hinged to hinged plate two, hinged plate two is rotatably connected to support plate, and support plate is fixedly connected to fixed shell;

[0008] The hinge plate has a movable groove on its surface. A protrusion of a sliding block is provided in the movable groove. The sliding block is slidably connected in the sliding seat. A clamping block is fixedly connected above the sliding block.

[0009] Preferably, the elastic limiting component includes a moving groove, and the moving groove is formed on the surface of the clamping block.

[0010] Preferably, multiple sets of the movable slots are provided, and springs are fixedly connected to the outer wall of the clamping block.

[0011] Preferably, the clamping block is elastically connected to the elastic block by a spring, and the surface of the elastic block is provided with an anti-slip surface. The spring keeps the elastic block in a certain position, and the anti-slip surface of the elastic block helps to better clamp the parts.

[0012] Preferably, the elastic block is hinged to a movable plate, and the movable plate is rotatably connected to the folding plate.

[0013] Preferably, the folding plate is slidably connected in the moving groove. When the outer movable plate is squeezed by an external force, the movable plate will drive the folding plate to slide in the moving groove because the movable plate is rotatably connected to the folding plate. The folding plate squeezes the elastic block in the middle, which can make the elastic block better fit the shape of the parts and achieve a tighter and more stable fixation.

[0014] This utility model provides a device for fixing mechanical parts. It has the following advantages:

[0015] (1) The mechanical parts fixing device uses a fixed device to start the hydraulic cylinder, which pushes the hinge block to move. When the hinge block moves, it will cause the hinge plate one to swing around its hinge point. The swing of the hinge plate one will cause the hinge plate two to move as well. When the hinge plate two moves, under the limit of the protrusion, it will cause the sliding block to slide in the sliding seat. The sliding of the sliding block will cause the clamping block to move in the horizontal direction. The operator can accurately adjust the stroke of the hydraulic cylinder according to the size of the parts and the fixing requirements, thereby controlling the position of the clamping block and ensuring that the parts will not be displaced during the processing.

[0016] (2) When the clamping block of the mechanical parts is attached to the mechanical parts by the setting of the limiting component, the outer movable plate is squeezed by external force. Since the movable plate is rotatably connected to the folding plate, the movable plate will drive the folding plate to slide inward in the moving groove. The folding plate squeezes the elastic block in the middle, which can make the elastic block better fit the shape of the parts and achieve a tighter and more stable fixation. The elastic block can be adjusted according to the actual shape of the parts, ensuring effective fixation of the parts and improving the versatility of the device. Attached Figure Description

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 This utility model proposes a mechanical component fixing device, including a base 1, a fixing frame 2 fixedly connected to the outer wall of the base 1, a pressing component 3 provided on the fixing frame 2, the base 1 provides an installation position for the pressing component 3, the pressing component 3 achieves pressing of the component through a mechanical structure, a fixing shell 4 fixedly connected to the outer wall of the base 1, the fixing shell 4 limits the component body 5 through a fixing device 6, the fixing device 6 is provided with an elastic limiting component 7, and the fixing device 6 includes a relief groove 61.

[0029] In this embodiment of the utility model, in order to achieve precise positioning and fixation and ensure processing accuracy, specifically, a clearance groove 61 is provided on the outer wall of the fixed shell 4, and a hydraulic cylinder 62 is provided in the inner cavity of the fixed shell 4. The output end of the hydraulic cylinder 62 is fixedly connected to the hinge block 63. When the hydraulic cylinder 62 is started, its output end will push the hinge block 63 to move. The hinge block 63 is hinged to the first hinge plate 64, and the first hinge plate 64 is hinged to the second hinge plate 65. The second hinge plate 65 is rotatably connected to the support plate 66, and the support plate 66 is fixedly connected to the fixed shell 4. When the hinge block 63 moves, it will drive the first hinge plate 64 to swing around its hinge point. The swing of the first hinge plate 64 This will cause the hinge plate 65 to move as well. The surface of the hinge plate 65 has a movable groove 67, and a protrusion of the sliding block 68 is provided in the movable groove 67. The sliding block 68 is slidably connected in the sliding seat 69. A clamping block 610 is fixedly connected above the sliding block 68. When the hinge plate 65 moves, under the limitation of the protrusion, it will drive the sliding block 68 to slide in the sliding seat 69. The sliding of the sliding block 68 will cause the clamping block 610 to move in the horizontal direction. The operator can accurately adjust the stroke of the hydraulic cylinder 62 according to the size of the part and the fixing requirements, thereby controlling the position of the clamping block 610 and ensuring that the part will not be displaced during the processing.

[0030] Furthermore, in order to enable the elastic block 73 to be adjusted according to the actual shape of the component, ensuring effective fixation of the component and improving the versatility of the device, the elastic limiting component 7 specifically includes a moving groove 71. The surface of the clamping block 610 is provided with the moving groove 71, and multiple sets of moving grooves 71 are provided. A spring 72 is fixedly connected to the outer wall of the clamping block 610. The clamping block 610 is elastically connected to the elastic block 73 through the spring 72. The surface of the elastic block 73 is provided with an anti-slip surface 74, and the spring 72 keeps the elastic block 73 in a certain position. Furthermore, the anti-slip surface 74 on the surface of the elastic block 73 helps to better clamp the parts. The elastic block 73 is hinged to a movable plate 75, which is rotatably connected to the folding plate 76. The folding plate 76 is slidably connected in the moving groove 71. When the outer movable plate 75 is squeezed by external force, due to the rotatable connection between the movable plate 75 and the folding plate 76, the movable plate 75 will drive the folding plate 76 to slide in the moving groove 71. The folding plate 76 squeezes the elastic block 73 in the middle, which can make the elastic block 73 better fit the shape of the parts and achieve a tighter and more stable fixation.

[0031] In this invention, during use, activating the hydraulic cylinder 62 causes its output end to push the hinge block 63 to move. When the hinge block 63 moves, it causes the first hinge plate 64 to swing around its hinge point. The swinging of the first hinge plate 64 causes the second hinge plate 65 to move as well. When the second hinge plate 65 moves, under the limiting position of the protrusion, it causes the sliding block 68 to slide within the sliding seat 69. The sliding of the sliding block 68 causes the clamping block 610 to move horizontally. The operator can accurately adjust the stroke of the hydraulic cylinder 62 according to the size of the parts and the fixing requirements, thereby controlling the clamping block 610. Position 10 ensures that the parts will not shift during processing. When the clamping block 610 is attached to the mechanical parts, the outer movable plate 75 is squeezed by external force. Since the movable plate 75 is rotatably connected to the folding plate 76, the movable plate 75 will drive the folding plate 76 to slide inward in the moving groove 71. The folding plate 76 squeezes the elastic block 73 in the middle, which can make the elastic block 73 better fit the shape of the parts, achieve a tighter and more stable fixation, and allow the elastic block 73 to be adjusted according to the actual shape of the parts, ensuring effective fixation of the parts and improving the versatility of the device.
