Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a polishing clamping fixture for sheet metal parts of intelligent electrical control boxes. Background Technology

[0002] An electrical control box is a device that integrates power control, protection, and monitoring. It contains one or more low-voltage switchgear devices and related control, measurement, signaling, protection, and regulation equipment. The main body of the electrical control box is composed of sheet metal parts. During the manufacturing process of sheet metal parts, the edges of the sheet metal parts need to be ground and polished. To ensure the stability of the sheet metal parts during polishing, clamping fixtures are used.

[0003] When using a clamping fixture, the sheet metal part is placed on the mounting base, and a cylinder moves a clamping block to press it onto the sheet metal part, thus clamping and fixing it. After activating the grinding structure, grinding can then proceed. However, in existing clamping fixtures, the clamping block is used directly for clamping and fixing. The contact between the clamping block and the sheet metal part is rigid; excessive force can damage the sheet metal part. Furthermore, the direct contact between the clamping block and the sheet metal part results in low friction, which can easily cause the sheet metal part to shift during polishing, thus affecting the polishing effect. Additionally, the polishing debris generated during the process is not effectively handled, adversely affecting the processing environment. Utility Model Content

[0004] The main purpose of this utility model is to provide a polishing clamping fixture for sheet metal parts of intelligent electrical control boxes, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A polishing clamping fixture for sheet metal parts of an intelligent electrical control box includes a base, a placement seat mounted on the base, a support frame mounted on one end of the base, a telescopic cylinder mounted on the support frame, and a clamping structure connected to the lower end of the telescopic cylinder. A dust collection component is mounted on the base.

[0007] Preferably, the lower end of the telescopic cylinder is provided with a connecting shaft, and the clamping structure is installed at the end of the connecting shaft, with the clamping structure located above the placement seat.

[0008] Preferably, the clamping structure includes a lifting plate, a connector, and an elastic clamping assembly. The lifting plate is fixedly connected to the connector, and the connector is provided with a connecting screw hole. The connector is installed at the lower end of the connecting shaft through the connecting screw hole, and the elastic clamping assembly is installed on the lifting plate.

[0009] Preferably, the elastic clamping assembly includes a guide sleeve, a movable rod, a pressure plate, a clamping spring, a rubber pad, a protrusion, a limiting plate, and a buffer spring. The guide sleeve is fixed to the lifting plate, the movable rod is fixedly connected to the pressure plate and passes through the lifting plate and the guide sleeve, the clamping spring is sleeved on the movable rod and located between the pressure plate and the lifting plate, the protrusion is evenly distributed on the rubber pad and the rubber pad is installed on the lower surface of the pressure plate, the limiting plate is installed on the upper end of the movable rod by screws, and the buffer spring is sleeved at the upper end of the movable rod.

[0010] Preferably, the vacuuming assembly includes a slide rail, a slide base, a mounting plate, a suction pipe, a malleable tube, and a vacuum hood. The slide base is slidably connected to the slide rail, and the slide rail is fixed to the base. The mounting plate is mounted on the slide base. The suction pipe is connected to the malleable tube and is mounted on the mounting plate. The vacuum hood is located at the end of the suction pipe.

[0011] Compared with the prior art, this utility model has the following beneficial effects: This polishing clamping fixture for sheet metal parts of intelligent electrical control boxes, through the set clamping structure, has elastic pressing components arranged in a ring array on the lifting plate. The elastic pressing components are equipped with a retaining spring. The sheet metal parts are clamped and fixed by elastic pressing, which can avoid excessive force on the sheet metal parts and prevent damage to the sheet metal parts. The rubber pad with protrusions on the lower surface of the pressure plate can increase the friction between the sheet metal parts and ensure that the sheet metal parts will not shift during the polishing process, thus ensuring the polishing effect. When the elastic pressing components are arranged in a ring array, they can be adapted to the concave and convex surfaces of the sheet metal parts to maximize the pressing effect. The dust collection component is used in conjunction with a vacuum cleaner to collect dust during the polishing process, preventing debris and dust from being dispersed into the air. At the same time, the mounting plate and other structures can move on the slide rail through the slide block, which is highly flexible in use. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-4 As shown, a polishing clamping fixture for sheet metal parts of an intelligent electrical control box includes a base 1, a placement seat 2 mounted on the base 1, and a support frame 3 mounted on one end of the base 1. A telescopic cylinder 4 is mounted on the support frame 3, and a clamping structure 5 is connected to the lower end of the telescopic cylinder 4. A dust collection assembly 6 is mounted on the base 1. A connecting shaft 7 is provided at the lower end of the telescopic cylinder 4, and the clamping structure 5 is mounted at the end of the connecting shaft 7, positioned above the placement seat 2.

[0019] The vacuuming assembly 6 includes a slide rail 601, a slide base 602, a mounting plate 603, a suction pipe 604, a malleable tube 605, and a vacuum hood 606. The slide base 602 is slidably connected to the slide rail 601, and the slide rail 601 is fixed on the base 1. The mounting plate 603 is mounted on the slide base 602. The suction pipe 604 is connected to the malleable tube 605, and the suction pipe 604 is disposed on the mounting plate 603. The vacuum hood 606 is disposed at the end of the suction pipe 604.

[0020] When polishing sheet metal parts, the sheet metal parts are placed on the placement seat 2 on the base 1. The telescopic cylinder 4 on the support frame 3 is activated, which drives the connecting shaft 7 and the clamping structure 5 to descend. The clamping structure 5 clamps and fixes the sheet metal parts on the placement seat 2. The grinding structure is activated to grind and polish the edges of the sheet metal parts. At the same time, the vacuum cleaner is activated to suck up the debris and dust generated during grinding. The debris and dust are sucked into the malleable tube 605 by the vacuum hood 606, and then enter the vacuum cleaner through the suction pipe 604 at the upper end of the mounting plate 603, thus achieving the dust removal effect during polishing. During the use of the vacuum assembly 6, the slide 602 can move along the slide rail 601. In conjunction with the malleable tube 605, the direction and position of the vacuum hood 606 can be flexibly changed, providing high flexibility of use.

[0021] According to the above implementation scheme, the clamping structure 5 includes a lifting plate 501, a connector 502 and an elastic pressing component 503. The lifting plate 501 is fixedly connected to the connector 502, and the connector 502 is provided with a connecting screw hole. The connector 502 is installed at the lower end of the connecting shaft 7 through the connecting screw hole, and the elastic pressing component 503 is installed on the lifting plate 501.

[0022] When using the clamping structure 5, as the connecting shaft 7 descends, the connecting head 502 lowers along with the lifting plate 501 and the elastic clamping assembly 503. After the elastic clamping assembly 503 contacts the sheet metal part, the lifting plate 501 continues to descend, applying an elastic force to the sheet metal part through the elastic clamping assembly 503 to ensure the stability of the sheet metal part, which can then be polished.

[0023] The elastic clamping assembly 503 includes a guide sleeve 5031, a movable rod 5032, a pressure plate 5033, a clamping spring 5034, a rubber pad 5035, a protrusion 5036, a limiting plate 5037, and a buffer spring 5038. The guide sleeve 5031 is fixed on the lifting plate 501. The movable rod 5032 is fixedly connected to the pressure plate 5033 and passes through the lifting plate 501 and the guide sleeve 5031. The clamping spring 5034 is sleeved on the movable rod 5032 and located between the pressure plate 5033 and the lifting plate 501. The protrusion 5036 is evenly distributed on the rubber pad 5035 and the rubber pad 5035 is installed on the lower surface of the pressure plate 5033. The limiting plate 5037 is installed on the upper end of the movable rod 5032 by screws. The buffer spring 5038 is sleeved at the upper end of the movable rod 5032.

[0024] During the clamping and fixing of the sheet metal part, the rubber pad 5035 on the lower surface of the pressure plate 5033 in the elastic clamping assembly 503 first contacts the sheet metal part. Under the limiting action of the sheet metal part, the pressure plate 5033, rubber pad 5035, and movable rod 5032 no longer move. The lifting plate 501, with the guide sleeve 5031, descends and compresses the clamping spring 5034 until the clamping and fixing of the sheet metal part is completed. In this process, since the elastic clamping assembly 503 on the lifting plate 501 is independently set, it can adapt to different height parts of the sheet metal part, and the clamping effect is good. During the clamping process, the clamping spring 5034 applies an elastic force, which can avoid damage to the sheet metal part due to excessive force. At the same time, the protrusion 5036 on the lower surface of the rubber pad 5035 contacts the sheet metal part, providing greater friction and increasing the clamping and fixing effect.

[0025] When it is necessary to remove the sheet metal part, the connecting shaft 7 raises the lifting plate 501, and through the buffer spring 5038 and the limiting plate 5037, it raises the moving rod 5032 and the pressure plate 5033 to reset. Then the sheet metal part can be removed. During this process, the buffer spring 5038 plays a buffering role to prevent the guide sleeve 5031 from directly hitting the limiting plate 5037, thus ensuring the integrity of the guide sleeve 5031 and the limiting plate 5037.

[0026] It should be noted that, through the clamping structure 5, elastic pressing components 503 are arranged in a circular array on the lifting plate 501. A retaining spring 5034 is installed in the elastic pressing component 503. The elastic pressing clamping achieves clamping and fixing of the sheet metal part, avoiding excessive force on the sheet metal part and preventing damage. A rubber pad 5035 with protrusions 5036 is provided on the lower surface of the pressure plate 5033, which increases the friction between the sheet metal part and the plate, ensuring that the sheet metal part does not shift during polishing and guaranteeing the polishing effect. The circular array of elastic pressing components 503 can adapt to the concavity and convexity of the sheet metal part when pressing it, maximizing the pressing effect. A dust collection component 6 is used in conjunction with a vacuum cleaner to collect dust during polishing, preventing debris and dust from scattering into the air. Simultaneously, the mounting plate 603 and other structures can move on the slide rail 601 via the slide block 602, providing high flexibility.

[0027] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
