Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a part fixing device for machining. Background Technology

[0002] Machining refers to the process of changing the shape, size, or properties of a workpiece using mechanical equipment. It can be divided into cutting and pressure processing according to the difference in processing methods.

[0003] An existing patent (publication number: CN213998552U) discloses a part fixing device for machining and manufacturing, including a fixing base. The upper surface of the fixing base has a first sliding groove, and the left and right sides of the fixing base both have second sliding grooves. A clamping frame is provided on the upper surface of the fixing base, and a slider is provided on the lower surface of the clamping frame. Third sliding grooves are provided on both the front and rear sides of the inner side of the clamping frame, and a sliding rod is provided inside the third sliding groove. This part fixing device for machining and manufacturing, through the inclusion of an adjustment device, achieves clamping of the part by the clamping frame. It is convenient and stable to operate, easy for users, and improves work efficiency. The handle, connecting rod, spring, sliding rod, and pressure plate work together to press the part firmly, making the part more secure and easier to operate, further improving work efficiency.

[0004] During use, the clamping frames in the aforementioned fixing device are arranged in a relatively compact manner, which limits the internal space when machining parts. Furthermore, because the parts are in close contact with the fixing base, it is impossible to machine the other side of the fixing base. When machining the other side is required, the parts need to be repositioned and fixed, which is a rather cumbersome process. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a part fixing device for machining, which has the advantages of precise adjustment for machining inclined or reverse surfaces of parts, and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a part fixing device for machining, comprising a base, wherein adjusting plates are symmetrically distributed on both sides of the top of the base along its length direction, and the two adjusting plates can slide synchronously in the vertical direction, a flipping motor is fixed on the side of the two adjusting plates opposite to each other, a bearing plate is provided between the two adjusting plates, and the motor shaft of the flipping motor passes through the adjusting plate and is fixedly connected to the bearing plate.

[0007] The upper surface of the support plate has multiple irregularly shaped plates distributed at the edge of the notch. These irregularly shaped plates move synchronously toward the center of the support plate. Each irregularly shaped plate is fixedly connected to two threaded rods, and each threaded rod is threadedly connected to a threaded sleeve. A conical rubber clamp is fixedly connected to the outside of the threaded sleeve.

[0008] Furthermore, a cylinder is fixed to the back of each irregularly shaped plate on the support plate, and the piston end of each cylinder is fixedly connected to the corresponding irregularly shaped plate.

[0009] The above solution uses a cylinder to drive the irregularly shaped plate to slide on the support plate, thereby flexibly adjusting the clamping force and position of the rubber clamps on the parts to meet the fixing requirements of parts of different shapes and sizes.

[0010] Furthermore, each of the irregularly shaped plates has a limiting groove inside along its sliding direction, and a positioning post is fixed on the bearing plate at the position corresponding to each limiting groove.

[0011] With the above solution, during the sliding process of the irregular plate, the positioning post and the limiting groove slide relative to each other. The positioning post can limit the movement range of the irregular plate, prevent the irregular plate from shifting or shaking during the sliding process, and ensure that the irregular plate drives the rubber clamp to stably and accurately clamp the part, thereby improving the reliability of the part fixation.

[0012] Furthermore, an electric push rod is fixed on the inner wall of the base. The movable end of the electric push rod is fixedly connected to the adjustment plate. A set of limiting rods is also arranged on both sides of the base corresponding to the adjustment plate. The adjustment plate is slidably sleeved with the limiting rods.

[0013] Through the above scheme, the limiting rod can provide stable and precise guidance for the vertical sliding of the adjusting plate, prevent the adjusting plate from tilting or jamming during the sliding process, and ensure that the adjusting plate drives the bearing plate to rise and fall smoothly.

[0014] Furthermore, the inner side of the notch is provided with a plurality of adjustable rubber pads for supporting the parts, and each of the rubber pads is at the same horizontal plane as the irregular plate.

[0015] Through the above solution, multiple rubber pads can provide uniform support when the parts are placed, preventing the parts from deforming due to uneven local stress. The adjustable rubber pads can be flexibly adjusted according to the actual size and shape of the parts, better adapting to the load-bearing requirements of different parts.

[0016] Furthermore, the inner wall of the notch is provided with a groove, and each rubber pad is slidably inserted into the adjacent groove.

[0017] The above solution allows for horizontal positioning of the rubber pads by opening slots. Multiple rubber pad boxes have raised ends facing away from each other, and the raised parts of the rubber pads can contact the inner wall of the slots during sliding, preventing the rubber pads from falling off during the swinging of the support plate. When it is necessary to adjust the spacing between multiple rubber pads, the rubber pads can be pulled out of the slots, shortening the spacing between adjacent ends of the multiple rubber pads, thus facilitating the placement of small parts on the multiple rubber pads.

[0018] Furthermore, a reflector is fixedly installed in the central area along the length direction of the inner wall of the base, and pressure sensors are fixedly installed on both sides along the width direction of the bearing plate.

[0019] Through the above scheme, the installation of pressure sensors can improve the safety of workpiece flipping. Specifically, when the support plate has not risen to a safe height for flipping, one end of it will first interfere with and contact the base or obstacle. The pressure sensor installed at the contact end between the support plate and the base will be subjected to pressure. When the pressure value exceeds a preset threshold, the pressure sensor sends a signal to the external control equipment, which can then stop the flipping motor. The preset threshold can prevent workers from accidentally touching the pressure sensor, thus avoiding the equipment from stopping due to misjudgment. This ensures the safety of the support plate flipping and prevents it from colliding and deforming with the base. Secondly, the reflector is installed behind the workpiece, which makes it easier for workers standing in front of the workpiece to observe the processing on the back of the workpiece. This reduces the need for workers to stick their heads into the processing area to observe, thus reducing safety hazards.

[0020] Compared with the prior art, the technical solution of this utility model has the following beneficial effects: This machining part fixing device, through the cooperation of a shaped plate and an arc-shaped rubber clamp, can clamp parts of different thicknesses. The use of the rubber clamp prevents rigid contact with the parts from causing damage. The adjustable support plate makes it easy to lift the parts to a suitable height for processing. Furthermore, the rotating motor can reverse or tilt the support plate after it has been raised to a certain height, so that the other side or inclined side of the support plate faces upward, making it easier for the operator to process the other side or inclined side of the part. At the same time, after the parts are fixed, there is a large space reserved for the operator to process the parts. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Please see Figures 1-4 This embodiment of a machining part fixing device includes a base 1. Adjustment plates 2 are symmetrically distributed on both sides of the top of the base 1 along its length direction, and the two adjustment plates 2 can slide synchronously in the vertical direction. A flipping motor 3 is fixed on the side of the two adjustment plates 2 away from each other. A support plate 4 is provided between the two adjustment plates 2. The motor shaft of the flipping motor 3 passes through the adjustment plate 2 and is fixedly connected to the support plate 4. After the two support plates 4 move upward in the vertical direction to a certain height, the two flipping motors 3 drive the support plates 4 to flip, so that the other end of the part is on the top. A notch 5 is formed on the inner side of the support plate 4, and the operator processes the other side of the part through the notch 5.

[0025] Multiple irregularly shaped plates 6 are distributed on the upper surface of the support plate 4 at the edge of the notch 5. In this embodiment, the notch 5 is rectangular, so there are four irregularly shaped plates 6. The multiple irregularly shaped plates 6 move synchronously toward the center of the support plate 4. Two threaded rods 7 are fixedly connected to each irregularly shaped plate 6. A threaded sleeve 8 is threadedly connected to each threaded rod 7. A conical rubber clamp 9 is fixedly connected to the outside of the threaded sleeve 8. The rubber clamp 9 is designed to be larger at the top and smaller at the bottom. The upper end of the threaded sleeve 8 is umbrella-shaped to limit the rubber clamp 9. The umbrella-shaped threaded sleeve 8 can provide support for the rubber clamp 9 after the support plate 4 is reversed, which can prevent the part from separating from the rubber clamp 9 under the action of gravity. By setting the conical rubber clamp 9, when the part is clamped and fixed, the edge of the part can be embedded into the rubber clamp 9, causing the rubber clamp 9 to deform. Its deformed part is in close contact with the part, thereby fixing the part. Its advantage is that it can clamp and fix parts of different sizes and thicknesses.

[0026] A cylinder 11 is fixed to the back of each irregular plate 6 on the support plate 4. The piston end of the cylinder 11 is fixedly connected to the corresponding irregular plate 6. The irregular plate 6 is driven to slide on the support plate 4 by the cylinder 11, thereby flexibly adjusting the clamping force and position of the rubber clamp 9 on the parts to meet the fixing requirements of parts of different shapes and sizes. Each irregular plate 6 has a limit groove opened inside along its sliding direction, and a positioning post 10 is fixed at the position of each limit groove on the support plate 4. During the sliding of the irregular plate 6, the positioning post 10 slides relative to the limit groove. The positioning post 10 can limit the movement range of the irregular plate 6, prevent the irregular plate 6 from deviating or shaking during the sliding process, and ensure that the irregular plate 6 drives the rubber clamp 9 to clamp the parts stably and accurately, thereby improving the reliability of the parts fixing.

[0027] An electric push rod 12 is fixed on the inner wall of the base 1. The movable end of the electric push rod 12 is fixedly connected to the adjusting plate 2. The electric push rod 12 drives the adjusting plate 2 to move in the vertical direction. A set of limiting rods 13 are also arranged on the base 1 on both sides corresponding to the adjusting plate 2. The adjusting plate 2 is slidably sleeved with the limiting rods 13. The limiting rods 13 can provide stable and precise guidance for the vertical sliding of the adjusting plate 2, preventing the adjusting plate 2 from tilting or jamming during the sliding process, and ensuring that the adjusting plate 2 drives the bearing plate 4 to rise and fall smoothly. Multiple adjustable rubber pads 14 are provided on the inner side of the notch 5 for supporting parts. Each rubber pad 14 is on the same horizontal plane as the irregular plate 6. Multiple rubber pads 14 can provide uniform support when the parts are placed, avoiding deformation of the parts due to uneven local force. The adjustable rubber pads 14 can be flexibly adjusted according to the actual size and shape of the parts to better adapt to the load-bearing requirements of different parts. The inner wall of the notch 5 is provided with a slot 15, and each rubber pad 14 is slidably inserted into the slot 15. The slot 15 can limit the horizontal movement of the rubber pads 14. The opposite ends of the multiple rubber pads 14 are protruding. The protruding parts of the rubber pads 14 can contact the inner wall of the slot 15 when sliding, preventing the rubber pads 14 from falling off during the swing of the bearing plate 4 and causing unstable clamping. When it is necessary to adjust the spacing between the multiple rubber pads 14, the multiple rubber pads 14 are pulled out from the adjacent slots 15 respectively, so that the spacing between the adjacent ends of the multiple rubber pads 14 is shortened, making it easier to place small parts on the multiple rubber pads 14.

[0028] A reflector 16 is fixedly installed in the central area along the length of the inner wall of the base 1, and a safety gap exists between it and the support plate 4 to prevent the support plate 4 from contacting the reflector 16 during the flipping process. Pressure sensors 17 are fixedly installed on both sides of the support plate 4 along the width direction. The installation of pressure sensors 17 can improve the safety of workpiece flipping. Specifically, when the support plate 4 has not risen to a safe height for flipping, one end will first interfere with and contact the base 1 or an obstacle. The pressure sensor 17 installed at the contact end between the support plate 4 and the base 1 will be subjected to pressure. When the pressure value exceeds a preset threshold (the pressure sensor is existing technology), (The working principle of the technology will not be elaborated here.) The pressure sensor 17 sends a signal to the external control device, which can stop the operation of the flipping motor 3. By setting a preset threshold, it can prevent workers from accidentally touching the pressure sensor, which would cause the equipment to stop due to misjudgment. This ensures the safety of the bearing plate flipping and prevents it from colliding and deforming with the base 1. Secondly, the reflector 16 is set behind the workpiece, which makes it easy for workers standing in front of the workpiece to observe the processing of the back of the workpiece (such as when the milling cutter is processing a groove on the back of the workpiece). This reduces the situation where workers stick their heads into the processing area to observe, thus reducing safety hazards.

[0029] The working principle of the above embodiments is as follows: When clamping a part, the spacing between multiple rubber pads 14 can be adjusted by sliding the rubber pads 14 to prevent parts of different sizes from being clamped. Then, the part is placed on the multiple rubber pads 14. Subsequently, multiple cylinders 11 push multiple irregular plates 6 to be located below the part, so that the rubber clamping block 9 contacts the part, and the edge of the part is embedded in the rubber clamping block 9, causing the rubber clamping block 9 to deform. The part is fixed by using the contact between the deformed part of the rubber clamping block 9 and the part. By adjusting the height of the threaded sleeve 8 on the threaded rod 7, the rubber clamping block 9 can clamp and fix parts of different sizes and thicknesses.

[0030] When the other side of the part needs to be processed, the two electric push rods 12 drive the two adjusting plates 2 to rise axially along the limiting rod 13, and drive the part on the bearing plate 4 to rise together. When the bearing plate 4 rises to a certain height, the two flipping motors 3 drive the bearing plate 4 to reverse or tilt. Then the electric push rod 14 drives the bearing plate 4 to fall, maintaining a safe distance from the base 1.
