Description

Technical Field

[0001] The invention relates to the technical field of turning processing, and in particular to a clamping tool for processing automobile parts. Background Art

[0002] Turning is a method of cutting on a lathe by rotating the workpiece relative to the tool. Since auto parts are various units that constitute the entire car and a product that serves the car, and there are many types of auto parts, the main structure of the car body is generally made of steel plates stamped and welded with steel pipes. The steel pipes include rectangular steel pipes and round steel pipes. During processing, round steel pipes often need to be drilled on the surface for better assembly; since the surface of auto parts is smooth, it is easy to deviate during turning and drilling. Therefore, clamping tools are needed to position auto parts, which can quickly position the workpiece to a suitable processing position and effectively reduce processing errors caused by workpiece movement or vibration; currently, when processing parts, it is necessary to use a fixture in a turning bed to position the parts, accurately process the parts, and workers are required to manually take out and place auto parts frequently. However, when workers take out the parts, they need a certain amount of preparation time and operation process to wait for the clamping tool to loosen the parts, making it difficult to control the accuracy of each removal and placement, which may cause the workpiece position to deviate, reduce the accurate positioning of the parts by the clamping tool, and affect the processing accuracy. Summary of the invention

[0003] The object of the present invention is to provide a clamping tool for processing automobile parts. Through the setting of the positioning component, the workpiece can be supported between two clamping tool parts, which is conducive to the workpiece being stably clamped in the middle of the two clamping tool parts, so that the position of the workpiece and the turned part are precisely positioned, thereby controlling the accuracy of each removal and placement, preventing the workpiece from being offset, improving the precise positioning of the clamping tool for the accessories, and improving the processing accuracy of the accessories, so as to solve the above-mentioned deficiencies in the technology.

[0004] In order to achieve the above-mentioned object, the present invention provides the following technical solution: a clamping tool for processing automobile parts, comprising:

[0005] A lathe, a turning part and a workpiece, wherein the turning part is used for turning the workpiece, the top end of the lathe is slidably connected with two symmetrical slide rails, both slide rails are equipped with clamping fixtures, and the clamping fixtures are used for clamping and positioning the workpiece on one side of the turning part;

[0006] Two groups of positioning components are used to position the center of the workpiece in the clamping fixture and feed the workpiece to the turning part to maintain precise positioning. Each group of the positioning components includes a support seat installed on the slide rail, a positioning frame installed on the support seat for placing the workpiece, and a positioning ring frame installed in the middle of the bottom of the clamping fixture. A slide for the positioning frame to slide up and down is installed on one side of the support seat. A guide component is installed on the support seat to drive the slide to slide intermittently along one side of the support seat and push the positioning frame to move along one side of the positioning ring frame into the clamping fixture. Two symmetrical connecting frames are installed at one end of the positioning ring frame, and the two connecting frames are located below the clamping fixture. Cleaning parts are fixed at one end of the two connecting frames, and the two cleaning parts are used to clean the workpiece close to the outside of the positioning ring frame. A relative component is provided in the guide assembly , which is used to drive the cleaning part to maintain relative sliding between one end of the positioning ring frame and the workpiece; and the positioning ring frame and the positioning frame are combined to form a hollow L-shaped structure, and the bottom of the positioning ring frame contacts the top of the workpiece on the positioning frame, which is convenient for restricting the two ends of the workpiece on the positioning frame, so that the workpiece remains stable on the positioning frame, thereby ensuring that when the positioning frame drives the workpiece to move inside the clamping fixture, it is beneficial to maintain precise positioning between the clamping fixture and the workpiece; at the same time, when the positioning frame moves downward and is located at the top of the support seat, the workpiece on the positioning frame slides out of the clamping fixture and is located at the bottom of the clamping fixture, which is convenient for horizontally removing the workpiece from between the clamping fixture and the support seat or vertically removing the workpiece from between the positioning frame and the clamping fixture, thereby reducing the time required for clamping and unloading the workpiece, and facilitating multi-directional placement of the workpiece.

[0007] Preferably, the guide assembly includes a stabilizing slide installed on the slide and the bottom end of the support seat, a support frame fixed on the top of the support seat and a lifting rod fixed on the bottom end of the positioning frame, and one end of the lifting rod passes through the support frame and is fixed with a connecting column, and one end of the connecting column is installed with a guide column, one side of the slide is provided with a parallelogram groove for the guide column to slide, and the support seat is provided with a power component that drives the stabilizing slide to move; and the parallelogram groove is arranged in a parallelogram shape. When the guide column moves along the inclined part of the parallelogram groove, the guide column moves upward or downward along the parallelogram groove. When the guide column moves along the inclined part of the parallelogram groove to the parallel part of the parallelogram groove, it is used to alleviate the rapid change of the upward or downward position of the guide column along the parallelogram groove in the parallelogram groove, so that the positioning frame remains stable in the clamping tooling, which is convenient for positioning and placing or stably removing the workpiece in the clamping tooling, and further improving the precise positioning of the clamping tooling on the accessories.

[0008] Preferably, the power assembly includes two pulleys symmetrically installed on one side of the support seat, a transmission belt mounted on the two pulleys, and a fixing frame fixed on one side of the stabilizing slide and cooperating with the transmission belt. A servo motor is fixed on one side of the support seat, and the servo motor is used to drive one of the pulleys to rotate; and the transmission belt is used to transmit the stabilizing slide at the bottom of the support seat, so that the stabilizing slide slides along the bottom of the support seat.

[0009] Preferably, the relative component includes a limiting groove provided at the bottom of the positioning ring frame for the connecting frame to slide and a pull rod seat fixed at one end of the connecting frame, and one end of the pull rod seat passes through the positioning ring frame and is fixed with an extension column, and a sleeve matching the extension column is installed at the bottom of the positioning ring frame, and one side of the stabilizing slide seat is provided with a protrusion assembly for driving the extension column to move upward or downward; and the starting position of the pull rod seat is located at the top of the positioning ring frame, so that the connecting frame and the cleaning piece are located below the clamping tooling and form relative movement with the workpiece, which is convenient for cleaning particulate impurities adsorbed on the outside of the workpiece and keeping the outside of the workpiece clean, so that the workpiece and the clamping tooling can be stably positioned, and the interior of the sleeve is hollow, so that one end of the extension column can pass through the sleeve, which is used to guide the extension column to move along one side of the positioning ring frame to ensure the stability of the movement of the extension column.

[0010] Preferably, the boss assembly includes a connecting rod fixed on one side of the stabilizing slide and a limiting ring fixed on the bottom end of the extension column, a slope block is fixed on one side of the connecting rod, and a moving wheel matching with the slope block is installed on the bottom end of the limiting ring; and the slope block is arranged in a slope so that the moving wheel and the slope block maintain a slope match, and the moving wheel and the slope block are slidably connected, which can reduce the wear between the slope block and the moving wheel and increase the service life of each other.

[0011] Preferably, a spring is fixed between the sleeve and the limiting ring, and the spring is sleeved on the outside of the extension column. The spring itself is elastic, thereby giving a thrust to one side of the limiting ring, thereby increasing the elastic adaptive force between the limiting ring and the slope block, and then the extension column moves stably along the sleeve, which is beneficial to maintaining stable relative movement between the cleaning piece and the workpiece, ensuring stable cleaning of the outside of the workpiece.

[0012] Preferably, one side of the positioning ring frame is also provided with a sliding groove that is connected to the inside of the limiting groove for the pull rod seat to slide; and the sliding groove and the limiting groove are cross-staggered, so that the pull rod seat and the connecting frame can maintain stable movement on the positioning ring frame, which is beneficial for the cleaning part to maintain stability against the outside of the workpiece.

[0013] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0014] 1. By setting the positioning component, the workpiece can be supported between the two clamping tooling parts, which is conducive to the workpiece being stably clamped in the middle of the two clamping tooling parts, so that the workpiece position and the turned part are accurately positioned, thereby controlling the accuracy of each removal and placement, preventing the workpiece position from shifting, improving the precise positioning of the clamping tooling on the accessories, and improving the processing accuracy of the accessories.

[0015] 2. Through the arrangement of the positioning frame, the positioning ring frame and the clamping fixture, the positioning ring frame and the positioning frame are combined to form a hollow L-shaped structure, which is conducive to the positioning ring frame to fit the two ends of the workpiece in an up and down staggered manner, and is convenient for restricting the two ends of the workpiece on the positioning frame, so that the workpiece remains stable on the positioning frame, thereby ensuring that the positioning frame drives the workpiece to be accurately positioned in the middle of the clamping fixture, further improving the precise positioning between the clamping fixture and the workpiece.

[0016] 3. By setting the positioning frame, the support seat and the clamping fixture, the positioning frame and the clamping fixture are combined to form a hollow T-shaped structure, which is convenient for taking out or placing the workpiece on the positioning frame horizontally or vertically between the clamping fixture and the support seat, which is beneficial for multi-directional placement or removal of the workpiece, thereby reducing the time required for clamping and unloading the workpiece and improving the clamping efficiency of the clamping fixture for the workpiece.

[0017] 4. By setting the guide component, the positioning frame can be briefly stopped when moving upward or downward in the clamping tooling, so that the positioning frame remains stable in the clamping tooling, which is convenient for positioning and placing the workpiece in the clamping tooling or stably removing it, further improving the precise positioning of the clamping tooling for the accessories.

[0018] 5. Through the setting of relative components, the part of the workpiece located at the positioning ring frame and the cleaning part can be kept in relative sliding, which is convenient for sweeping impurities on the outside of the workpiece downward from its outside, reducing the adsorption of particulate impurities on the outside of the workpiece, keeping the outside of the workpiece clean, and enabling the workpiece to be clamped between the clamping tooling, further improving the stable positioning of the workpiece.

[0034] Two sets of positioning components 2 are used to position the center of the workpiece 14 in the clamping fixture 11, and feed the workpiece 14 to the turning part 13 to maintain accurate positioning. Each set of positioning components 2 includes a support seat 21 installed on the slide rail 12, a positioning frame 24 installed on the support seat 21 for placing the workpiece 14, and a positioning ring frame 25 installed in the middle of the bottom of the clamping fixture 11. A slide seat 23 for the positioning frame 24 to slide up and down is installed on one side of the support seat 21. A guide component 3 is installed on the support seat 21 to drive the slide seat 23 along the support seat 2 1 slides intermittently on one side and pushes the positioning frame 24 to move along one side of the positioning ring frame 25 into the clamping fixture 11. One end of the positioning ring frame 25 is equipped with two symmetrical connecting frames 26, and the two connecting frames 26 are located below the clamping fixture 11. One end of the two connecting frames 26 is fixed with a cleaning member 22, and the two cleaning members 22 are used to clean the workpiece 14 close to the outside of the positioning ring frame 25. A relative component 4 is provided in the guide component 3, which is used to drive the cleaning member 22 to keep sliding relative to the workpiece 14 along one end of the positioning ring frame 25.

[0035] The guide assembly 3 includes a stabilizing slide 39 installed at the bottom ends of the slide 23 and the support seat 21, a support frame 31 fixed on the top of the support seat 21, and a lifting rod 33 fixed on the bottom end of the positioning frame 24, and one end of the lifting rod 33 passes through the support frame 31 and is fixed with a connecting column 34, and a guide column 35 is installed at one end of the connecting column 34, and a parallelogram groove 32 for the guide column 35 to slide is opened on one side of the slide 23, and a power assembly for driving the stabilizing slide 39 to move is provided on the support seat 21; the power assembly includes two pulleys 36 symmetrically installed on one side of the support seat 21, a transmission belt 37 sleeved on the two pulleys 36, and a fixed frame fixed on one side of the stabilizing slide 39 and matched with the transmission belt 37, and a servo motor 38 is fixed on one side of the support seat 21, and the servo motor 38 is used to drive one of the pulleys 36 to rotate.

[0036] When the workpiece needs to be placed inside the clamping fixture 11 and the clamped fixture 11 is accurately positioned, the workpiece 14 is first placed on the positioning frame 24 and stably supported by the positioning frame 24, and one of the pulleys 36 is driven by the servo motor 38 to rotate, and then the outside of one of the pulleys 36 rubs against the transmission belt 37 and drives the transmission belt 37 to rotate. At this time, the rotation of the transmission belt 37 drives the other pulley 36 to rotate, so that the transmission belt 37 has a transmission effect, and the transmission belt 37 moves and drives the stable slide 39 to move left or right along the bottom of the support seat 21, and the movement of the stable slide 39 drives the slide 23 to slide along one side of the support seat 21, so that the parallelogram groove 32 slides between the guide column 35, and the guide column 35 is close to the inclined part of the parallelogram groove 32, so that the guide column 35 matches the inclination of the inclined part of the parallelogram groove 32, thereby driving the guide column 35 along the inclined part of the parallelogram groove 32 to move under the movement of the slide 23. The guide post 35 is supported at the horizontal position inside the parallelogram groove 32, so that the guide post 35 moves upward and drives the connecting post 34 to move synchronously, so that the lifting rod 33 penetrates the support frame 31 and pushes the positioning frame 24 to move toward the inside of the clamping fixture 11. At this time, the workpiece 14 moves upward and moves in contact with the positioning ring frame 25, and then the cleaning member 22 slides between the outside of the workpiece 14 to clean the particle impurities on the outside of the workpiece 14. Then the positioning frame 24 moves the workpiece 14 above it to the middle of the clamping fixture 11, which is conducive to the workpiece 14 being stably clamped in the middle of the two clamping fixtures 11, so that the position of the workpiece 14 is kept accurately positioned between the turned part 13, so that the accuracy of each removal and placement can be controlled, which can prevent the workpiece position from being offset, improve the accurate positioning of the clamping fixture on the accessories, and improve the processing accuracy of the accessories.

[0038] A spring 48 is fixed between the sleeve 47 and the limiting ring 44 , and the spring 48 is sleeved on the outside of the extension column 46 ; a sliding groove communicating with the inside of the limiting groove 43 for the pull rod seat 45 to slide is also opened on one side of the positioning ring frame 25 .

[0039] Through the above technical solution:

[0040] When the workpiece 14 on the positioning frame 24 is placed in or taken out of the clamping fixture 11, the stable slide 39 first moves along the bottom of the support seat 21, driving the connecting rod 41 to move synchronously along one side of the support seat 21, and the slope block 42 is driven to move synchronously by the movement of the connecting rod 41. Then, the slope block 42 and the moving wheel 49 are matched with each other in slope, and under the elastic force of the spring 48 itself, a downward thrust is given to one side of the limit ring 44, so that the moving wheel 49 and the slope block 42 are stably fitted. At this time, the movement of the slope block 42 drives the moving wheel 49 to move downward, and the moving wheel 49 The downward movement drives the extension column 46 to slide downward along the sleeve 47, and the movement of the extension column 46 drives the pull rod seat 45 to move downward along the slide groove and drives the connecting frame 26 to move downward along the limit groove 43, so that the movement of the connecting frame 26 drives the cleaning member 22 to slide downward along one side of the positioning ring frame 25, so as to facilitate the cleaning of impurities on the outside of the workpiece 14 along its outside, reduce the adsorption of particulate impurities on the outside of the workpiece 14, keep the outside of the workpiece 14 clean, so that the workpiece 14 can be clamped with the clamping tooling 11, and further improve the stable positioning of the workpiece 14.
