Description

Technical Field

[0001] The utility model belongs to the technical field of scale processing, and particularly relates to a fixture structure for processing metal fittings for scales. Background Technique

[0002] A scale, also called a "balance", refers to any instrument for weighing with unequal arms, or a suspension beam balance that measures the weight of an object by looking at the scale marks, or simply the balance beam.

[0003] Chinese Patent Application No. 202021555015.1 discloses a fixture structure for processing metal fittings for electronic scales, specifically including a base. On both sides of the top of the base, vertical plates are fixedly connected. On the opposite sides of the two vertical plates, clamping components are symmetrically installed. The clamping components include a cylinder, a slider, and a moving plate. The bottom of the cylinder is fixedly connected to the slider. On the side of the slider away from the vertical plate, a push rod is rotatably connected. On the side of the push rod away from the slider, the push rod is rotatably connected to the moving plate. On the side of the moving plate away from the push rod, an installation groove is opened. Inside the installation groove, a clamping plate is connected through a plurality of buffer components. The buffer components include a diamond-shaped frame and a buffer spring. The two ends of the diamond-shaped frame are arranged between the clamping plate and the inner wall of the installation groove. The buffer spring is horizontally arranged inside the diamond-shaped frame. The utility model solves the problems of inconvenient use and complex clamping method of the existing fixture structure, and improves the processing efficiency of metal fittings for electronic scales.

[0004] In the above patent, the metal fittings for the scale are clamped and fixed on the base for subsequent processing. The debris generated during the processing remains on the base. Subsequently, the operator needs to obtain cleaning tools from other places to clean the debris on the base, which is cumbersome and affects the work efficiency of the operator. In addition, when using a cylinder to push the clamping plate to move for clamping the metal fittings for the scale, the debris generated during the subsequent processing of the metal fittings for the scale is likely to splash onto the cylinder, which is likely to cause impurities in the cylinder or damage to the piston rod of the cylinder, affecting the normal operation of the cylinder, and further affecting the clamping effect of the clamping plate on the metal fittings for the scale. Content of the Utility Model

[0005] To solve the problems raised in the above background technique, the utility model provides a fixture structure for processing metal fittings for scales, which has the characteristics of being convenient for cleaning and collecting debris and moving protection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping structure for processing metal parts for scales, including a base, with vertical plates fixedly connected to both ends of the upper part of the base, and cylinders fixedly connected to the sides of the two vertical plates that are close to each other. A slider is fixedly connected to the output end of the cylinder, and a clamping mechanism is provided on the sides of the two sliders that are close to each other. A cleaning component is provided inside the base, and a protective component is provided on the side wall of the vertical plate and around the cylinder.

[0007] Preferably, the cleaning assembly includes a collection component, a mounting cavity, an electric push rod, a scraper, and a pushing plate. The mounting cavity is provided on the side wall of the base. An electric push rod is fixedly connected to the inner side wall of the mounting cavity. A pushing plate is fixedly connected to the output end of the electric push rod. A scraper is fixedly connected below the pushing plate. A collection component is provided below the base.

[0008] Preferably, the collecting component includes a guide plate, a collecting box, a plug-in plate, and a plug-in groove. The guide plate is fixedly connected to the side wall of the base. The collecting box is slidably connected to the bottom of the base and between two support plates. Plug-in plates are fixedly connected to both side walls of the collecting box. A plug-in groove is provided inside the support plate at the position corresponding to the plug-in plate.

[0009] Preferably, a guide platform is fixedly connected to the inner wall of the collection box, and the guide platform is set in an inclined state.

[0010] Preferably, the protective assembly includes a fixed cover, a receiving cavity, and a movable cover. The fixed cover is fixedly connected to the outer wall of the cylinder, and the movable cover is fixedly connected to the top of the slider. The receiving cavity is provided inside the fixed cover at the position corresponding to the movable cover.

[0011] Preferably, the protective assembly further includes a movable block and a movable groove. Movable blocks are fixedly connected to both sides of the movable cover near the receiving cavity, and a movable groove is provided on the inner wall of the receiving cavity at the position corresponding to the movable block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model is equipped with a cleaning component. After the metal parts for the scale are processed, the cylinder is started. The cylinder drives the slider to move. The slider moves the two clamping mechanisms to move back to back and fit against the two side walls of the base. The cylinder is then stopped, and the processed metal parts for the scale are removed from the base. The electric push rod inside the mounting cavity is started. The electric push rod drives the push plate to move. The push plate moves the scraper. During the scraper's movement, it can push the residual debris on the base away from the base. Then, under the action of the guide plate, it slides into the collection box, making it easy for the operator to clean and collect the debris generated after the metal parts for the scale are processed.

[0014] 2. This utility model is equipped with a protective component. The operation of the cylinder drives the slider to move, the slider to move the movable cover inside the receiving cavity, and the movable cover to move the movable block inside the movable groove. When the movable block moves and fits against the inner wall of the movable groove, the movable block is blocked and stops moving, thereby preventing the movable cover from continuing to move and preventing the movable cover from detaching from the fixed cover. During the subsequent processing of the metal parts for the scale, the fixed cover and the movable cover can prevent the debris generated during the processing from splashing onto the cylinder, thereby preventing the debris from falling into the cylinder or damaging the piston rod of the cylinder, ensuring the normal service life of the cylinder.

[0022] 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. Example 1

[0023] Please see Figure 1-6The present invention provides the following technical solution: a clamping structure for processing metal parts for scales, including a base 8, with vertical plates 1 fixedly connected to both ends of the upper part of the base 8, and cylinders 4 fixedly connected to the side of the two vertical plates 1 that are close to each other, with sliders 5 fixedly connected to the output end of the cylinders 4, and clamping mechanisms 3 provided on the side of the two sliders 5 that are close to each other, a cleaning component 6 provided inside the base 8, and a protective component 2 provided on the side wall of the vertical plates 1 and around the cylinders 4.

[0024] Specifically, the cleaning component 6 includes a collection element 61, a mounting cavity 62, an electric push rod 63, a scraper 64, and a pushing plate 65. The mounting cavity 62 is formed on the side wall of the base 8. The electric push rod 63 is fixedly connected to the inner side wall of the mounting cavity 62. The pushing plate 65 is fixedly connected to the output end of the electric push rod 63. The scraper 64 is fixedly connected below the pushing plate 65. The collection element 61 is located below the base 8.

[0025] By adopting the above technical solution, after the metal parts for the scale are processed, the processed metal parts for the scale are removed from the base 8. Then, the cylinder 4 drives the slider 5 to move. The movement of the slider 5 drives the two clamping mechanisms 3 to move back to back and fit against the side wall of the base 8. Then, the electric push rod 63 inside the mounting cavity 62 is activated. The operation of the electric push rod 63 drives the push plate 65 to move. The movement of the push plate 65 drives the scraper 64 to move. During the movement of the scraper 64, the residual debris on the base 8 can be pushed and fall into the collection part 61, which is convenient for the operator to clean up the residual debris on the base 8.

[0026] Specifically, the collecting component 61 includes a guide plate 611, a collecting box 612, a connecting plate 613, and a connecting groove 614. The guide plate 611 is fixedly connected to the side wall of the base 8. The collecting box 612 is slidably connected to the bottom of the base 8 and located between two support plates 7. The connecting plates 613 are fixedly connected to both side walls of the collecting box 612. The connecting groove 614 is provided inside the support plate 7 at the position corresponding to the connecting plate 613.

[0027] By adopting the above technical solution, the collection box 612 is moved and inserted into the lower part of the base 8, and the insertion plate 613 is inserted into the insertion slot 614. Subsequently, the scraper 64 moves and pushes the residual debris on the base 8 to move away from the base 8, and then slides into the collection box 612 under the action of the guide plate 611, which facilitates the collection of the cleaned debris.

[0028] Specifically, a guide platform is fixedly connected to the inner wall of the collection box 612, and the guide platform is set in an inclined state.

[0029] By adopting the above technical solution, the debris that falls into the collection box 612 slides down the guide plate to various parts of the collection box 612, avoiding the accumulation of debris at the end of the collection box 612 near the guide plate 611, and ensuring the collection volume of the collection box 612.

[0030] In this embodiment, the collection box 612 is moved and inserted into the lower part of the base 8, and the insertion plate 613 is then inserted into the insertion slot 614. The metal parts for the scale are then placed on top of the base 8, positioned between the two clamping mechanisms 3. The cylinder 4 is then activated, causing the slider 5 to move. The movement of the slider 5 causes the two clamping mechanisms 3 to move towards each other. Once the two clamping mechanisms 3 are in contact with the side walls of the metal parts for the scale, the cylinder 4 is stopped. The clamping mechanisms 3 can be used to clamp and fix the metal parts for the scale, facilitating subsequent processing. After the metal parts for the scale are processed... Start cylinder 4. Cylinder 4 drives slider 5 to move. Slider 5 moves and drives two clamping mechanisms 3 to move back to back and fit against the two side walls of base 8. Stop cylinder 4 and remove the processed metal parts for the scale from base 8. Start electric push rod 63 inside mounting cavity 62. Electric push rod 63 drives push plate 65 to move. Push plate 65 moves and drives scraper 64 to move. During the movement of scraper 64, it can push the residual debris on base 8 to move away from base 8. Then, under the action of guide plate 611, it slides into collection box 612, which is convenient for operators to clean and collect the debris generated after processing the metal parts for the scale. Example 2

[0031] The difference between this embodiment and embodiment 1 is that the protective component 2 includes a fixed cover 21, a receiving cavity 24, and a movable cover 25. The fixed cover 21 is fixedly connected to the outer wall of the cylinder 4, and the movable cover 25 is fixedly connected to the top of the slider 5. The receiving cavity 24 is provided inside the fixed cover 21 at the position corresponding to the movable cover 25.

[0032] Specifically, the protective component 2 also includes a movable block 22 and a movable groove 23. The movable cover 25 is fixedly connected to both sides of the end near the receiving cavity 24 by the movable block 22. The inner side wall of the receiving cavity 24 is provided with a movable groove 23 at the position corresponding to the movable block 22.

[0033] By adopting the above technical solution, the moving cover 25 moves and drives the moving block 22 to move inside the moving groove 23. When the moving block 22 moves and fits against the inner side wall of the moving groove 23, the moving block 22 is blocked and stops moving, thereby preventing the moving cover 25 from continuing to move and preventing the moving cover 25 from detaching from the fixed cover 21.

[0034] In this embodiment, the cylinder 4 drives the slider 5 to move, and the slider 5 moves the movable cover 25 inside the receiving cavity 24. The movable cover 25 moves the movable block 22 inside the movable groove 23. When the movable block 22 moves and fits against the inner wall of the movable groove 23, the movable block 22 is blocked and stops moving, thereby preventing the movable cover 25 from continuing to move and avoiding the movable cover 25 from detaching from the fixed cover 21. During the subsequent processing of the metal parts for the scale, the fixed cover 21 and the movable cover 25 can prevent the debris generated during the processing from splashing onto the cylinder 4, thereby preventing the debris from falling into the cylinder 4 or damaging the piston rod of the cylinder 4, and ensuring the normal service life of the cylinder 4.

[0035] In this utility model, the electric push rod 63 is a previously disclosed technology, and the selected model is SL42.

[0036] The structure and principle of the clamping mechanism 3, which consists of a push rod, a moving plate, a mounting groove, a clamping plate, a rhomboid frame, and a buffer spring, have been disclosed in Chinese patent application No. 202021555015.1, which discloses a clamping structure for processing metal parts for electronic scales. Its working principle is as follows: a push rod is rotatably connected to the side of the slider 5 away from the vertical plate 1, and the side of the push rod away from the slider 5 is rotatably connected to the moving plate. A mounting groove is provided on the side of the moving plate away from the push rod. A clamping plate is connected to the mounting groove through several buffer components. The buffer components include a rhomboid frame and a buffer spring. The two ends of the rhomboid frame are positioned between the clamping plate and the inner wall of the mounting groove. The buffer spring is laterally positioned inside the rhomboid frame. During use, as the slider 5 moves, the tilt angle of the push rod gradually increases, thereby pushing the moving plate to move. The moving plate then moves the clamping plate to clamp the metal parts. During clamping, the clamping plate achieves a buffering effect by squeezing the rhomboid frame and the buffer spring, preventing excessive clamping force from causing wear on the metal parts.

[0037] The working principle and usage process of this utility model are as follows: The collection box 612 is moved and inserted into the lower part of the base 8, and the insertion plate 613 is then inserted into the insertion slot 614. The metal parts for the scale are then placed on top of the base 8, positioned between the two clamping mechanisms 3. The cylinder 4 is then activated, causing the slider 5 to move. The movement of the slider 5 causes the two clamping mechanisms 3 to move towards each other. When the two clamping mechanisms 3 move and adhere to the side walls of the metal parts for the scale, the cylinder 4 is stopped. The clamping mechanisms 3 can be used to clamp and fix the metal parts for the scale, facilitating subsequent processing. Simultaneously, the slider 5 moves the two clamping mechanisms 3 towards each other, causing the movable cover 25 to move within the receiving cavity 24. The movement of the movable cover 25 causes the movable block 22 to move within the movable groove 23. When the movable block 22 moves and adheres to the inner side wall of the movable groove 23, the movable block 22 is obstructed and stops moving, thus preventing the movable cover 25 from moving further and avoiding further movement. After the fixed cover 21 is removed, during the subsequent processing of the metal parts for the scale, the fixed cover 21 and the movable cover 25 prevent the debris generated during processing from splashing onto the cylinder 4, thus preventing the debris from falling into the cylinder 4 or damaging the piston rod of the cylinder 4, ensuring the normal service life of the cylinder 4. After the metal parts for the scale are processed, the cylinder 4 is started. The operation of the cylinder 4 drives the slider 5 to move. The movement of the slider 5 drives the two clamping mechanisms 3 to move back to back and fit against the two side walls of the base 8. The cylinder 4 is then stopped, and the processed metal parts for the scale are removed from the base 8. The electric push rod 63 inside the mounting cavity 62 is started. The operation of the electric push rod 63 drives the push plate 65 to move. The movement of the push plate 65 drives the scraper 64 to move. During the movement of the scraper 64, the debris remaining on the base 8 can be pushed away from the base 8 and then slide into the collection box 612 under the action of the guide plate 611, making it easy for the operator to clean and collect the debris generated after the processing of the metal parts for the scale.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
