Description

Technical Field

[0001] This invention relates to the field of aluminum bar polishing technology, and more specifically, to a small aluminum bar polishing fixture. Background Technology

[0002] Small aluminum busbars are widely used in industries such as electrical equipment manufacturing and electronic components. To ensure the performance, appearance quality, and corrosion resistance of these busbars, surface polishing is necessary. However, existing polishing equipment has many shortcomings when processing small aluminum busbars. Traditional fixtures are often complex in structure and expensive; they are also poorly suited for the small batches and diverse specifications of these workpieces.

[0003] To address this problem, Chinese invention patent CN114346862A discloses a polishing and rust removal device for machining electromechanical equipment. The device includes a body with a rotating shaft on one side and a polishing wheel mounted on the shaft. A baffle is positioned directly above the polishing wheel and is inserted into the body. A collection tray is located on the front of the body, aligned with the bottom of the polishing wheel. A filter plate is located at the bottom of the tray. A fan is located at the bottom of the body, aligned with the collection tray. During polishing, the rotating shaft drives the polishing wheel to rotate, thus polishing the workpiece. The workpiece to be polished is located on the collection tray, and the rotating polishing wheel grinds and polishes the workpiece, achieving the polishing operation. Polishing debris is collected in the collection tray, and the filter plate filters the dust, preventing the generation of large amounts of airborne dust.

[0004] Although the above-mentioned polishing and rust removal device can achieve polishing of workpieces, the following problems still exist during its use.

[0005] In the process of polishing the workpiece using the aforementioned rust removal device, the workpiece is merely placed on the collection tray without being fixed in place. This makes it easy for the workpiece to move during the polishing process, which cannot guarantee the stability of the workpiece and thus affects the polishing effect.

[0006] To address this problem, the present invention provides a small aluminum busbar polishing fixture that ensures the stability of the aluminum busbar during the polishing process, thereby guaranteeing the polishing effect of the aluminum busbar. Summary of the Invention

[0007] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the invention, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0008] To address the technical problem of the inability to guarantee workpiece stability during polishing operations in existing technologies, the present invention adopts the following technical solution.

[0009] A small aluminum strip polishing fixture includes a fixed base, a support frame on the fixed base, an mounting plate on the support frame, a fixing plate on the fixed base, a polishing unit on the mounting plate and the fixing plate, and a clamping component on the fixed base. When the polishing unit polishes the aluminum strip, the clamping component clamps the aluminum strip, so that the aluminum strip can be polished stably.

[0010] Preferably, in the polishing fixture described above, the clamping assembly includes finger cylinders mounted on a fixed base. The power end of the finger cylinders is symmetrically equipped with clamping heads. The operation of the finger cylinders can drive the clamping heads to move closer to each other or further apart, thereby clamping and fixing the aluminum strip.

[0011] Preferably, in the polishing fixture described above, a support plate is provided at one end of the finger cylinder near the clamping head, and the clamping head is slidably mounted on the support plate. However, when the finger cylinder drives the clamping head to move, the clamping head moves along the length direction of the support plate.

[0012] Preferably, in the above-mentioned polishing fixture, the bearing plate is provided with a fixing groove, and the clamping head includes a connecting plate. The end of the connecting plate is connected to a connector, which is slidably assembled in the fixing groove. Therefore, when the finger cylinder drives the clamping head to move, the connecting plate drives the connector to slide in the fixing groove.

[0013] Preferably, in the above-mentioned polishing fixture, the clamping head is further provided with a buffer mechanism to buffer the clamping force of the clamping head. The buffer mechanism includes a clamping plate and a spring. The clamping plate is connected to the side wall of the opposite side of the connecting plate by the spring. When the clamping heads work together to clamp the aluminum busbar, the clamping plate contacts the aluminum busbar, causing the spring to compress, thereby buffering the clamping force of the clamping head.

[0014] Preferably, in the above-mentioned polishing fixture, a guide plate is installed on the fixed base, and the clamping head is slidably assembled with the guide plate. When the finger cylinder drives the clamping head to move, the clamping head moves along the length direction of the guide plate.

The polishing machine I includes a drive motor I mounted on a fixed plate, and a drive wheel I is also mounted on the fixed plate. In addition, a driven wheel I is also mounted on the mounting plate, and a polishing abrasive belt is sleeved between the drive wheel I and the driven wheel I. When the drive motor I is working, it drives the drive wheel I to rotate, thereby driving the polishing abrasive belt to rotate and polish the aluminum strip.

[0016] Preferably, in the above-mentioned polishing fixture, the polishing unit is a polishing machine II. The polishing machine II includes a drive motor II mounted on a mounting plate. In addition, a drive wheel II is mounted on the mounting plate, and a driven wheel II is mounted on the fixed plate. The drive wheel II and the driven wheel II are connected by a polishing abrasive belt.

[0017] Preferably, in the above-mentioned polishing fixture, the polishing unit includes polishing machine I and polishing machine II. Polishing machine I includes a drive motor I mounted on a fixed plate, and a drive wheel I is also mounted on the fixed plate. In addition, a driven wheel I is also mounted on the mounting plate, and a polishing abrasive belt is sleeved between the drive wheel I and the driven wheel I. When the drive motor I is working, it drives the drive wheel I to rotate, thereby driving the polishing abrasive belt to rotate and polish the aluminum busbar. Polishing machine II includes a drive motor II mounted on a mounting plate, and a drive wheel II is also mounted on the mounting plate. A driven wheel II is mounted on the fixed plate. The drive wheel II and the driven wheel II are connected by a polishing abrasive belt. When the drive motor II is working and drives the drive wheel II to rotate, it can drive the polishing abrasive belt to rotate, thereby polishing the aluminum busbar.

[0018] Preferably, in the above-mentioned polishing fixture, the driven wheel I and driven wheel II are respectively connected to the fixed plate and the mounting plate via connecting arms, and the connecting arms are respectively connected to the fixed plate and the mounting plate via torsion springs. Furthermore, when the polishing abrasive belt is respectively fitted onto the driving wheel I and driven wheel I, the torsion spring between the connecting arm on driven wheel I and the mounting plate is in a stored state.

[0019] Compared with the prior art, the beneficial effects of the present invention are: The polishing fixture of this invention includes polishing machine I and polishing machine II. Polishing machine I and polishing machine II can simultaneously polish both sides of the aluminum strip, thereby ensuring polishing efficiency. In addition, the driven wheels in polishing machine I and polishing machine II can adaptively tension the polishing belt, thereby ensuring polishing efficiency. During the polishing process, the aluminum strip is clamped and fixed by the clamping assembly, thereby ensuring the stability of the aluminum strip during polishing. Furthermore, when the clamping assembly clamps and fixes the aluminum strip, it can buffer the aluminum strip through springs and clamping plates, thereby avoiding the problem of damage to the aluminum strip due to excessive clamping force.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below. Example

[0025] like Figure 1 as well as Figure 2As shown, this is a schematic diagram of the polishing fixture in this embodiment. The polishing fixture in this embodiment is used to process and polish small aluminum bars. The polishing fixture in this embodiment includes a fixed base 100, on which a support frame 101 is fixedly connected. The polishing fixture also includes a polishing unit 200. In addition, a clamping assembly 300 is provided on the fixed base 100. The clamping assembly 300 is used to clamp the small aluminum bars. After clamping, the polishing unit 200 grinds and polishes the small aluminum bars, thereby completing the polishing operation.

[0026] like Figures 4-9 As shown, to ensure the stability of the small aluminum strip during the polishing process, the clamping assembly 300 in this embodiment stably clamps the small aluminum strip, thereby ensuring its stability during the grinding and polishing process. The clamping assembly 300 in this embodiment includes a finger cylinder 301 fixedly mounted on the fixed base 100, as shown... Figure 4 As shown, a support plate 302 is fixedly connected to the end of the finger cylinder 301, and a clamping head 303 is slidably mounted on the support plate 302. The clamping head 303 is connected to the power end of the finger cylinder 301. Figure 4 , Figure 5 as well as Figure 6 As shown in this embodiment, when it is necessary to clamp a small aluminum strip, the finger cylinder 301 drives the clamping heads 303 to move closer to each other to clamp the small aluminum strip between the clamping heads 303. This ensures the stability of the polishing unit 200 during the polishing process of the small aluminum strip, and improves the polishing efficiency and effect.

[0027] like Figure 5 As shown, in order to ensure the stable movement of the gripping head 303, a guide plate 104 is installed on the fixed base 100 in this embodiment, and the gripping head 303 is slidably assembled with the guide plate 104. Therefore, when the finger cylinder 301 drives the gripping head 303 to move, the gripping head 303 moves along the length direction of the guide plate 104, thereby ensuring the stability of the gripping head 303 during the movement.

[0028] like Figure 6 as well as Figure 8 As shown, in order to further ensure the stability of the clamping head 303 during movement, the support plate 302 in this embodiment has a fixing groove 302a on one side of the clamping head 303. The clamping head 303 is slidably assembled with the support plate 302 through the mutual cooperation of the connector 304 and the fixing groove 302a. Therefore, during the movement of the clamping head 303 driven by the finger cylinder 301, the clamping head 303 drives the connector 304 to slide in the fixing groove 302a, thereby further ensuring the smoothness of the clamping head 303 during movement.

[0029] In addition, such as Figure 1as well as Figure 3 As shown, the polishing unit 200 in this embodiment also includes polishing machine I 201 and polishing machine II 202. In this embodiment, polishing machine I 201 and polishing machine II 202 work synchronously so that the aluminum busbar can be polished on both sides at the same time, thereby ensuring the polishing efficiency of the aluminum busbar.

[0030] like Figure 3 As shown, in this embodiment, the polishing machine I201 includes a drive motor I201a mounted on a fixed plate 102, and a drive wheel I201b is also mounted on the fixed plate 102. In addition, a driven wheel I201c is also mounted on the mounting plate 103. A polishing abrasive belt is sleeved between the drive wheel I201b and the driven wheel I201c. When the drive motor I201a works, it drives the drive wheel I201b to rotate, thereby driving the polishing abrasive belt to rotate and polish the aluminum strip.

[0031] In addition, such as Figure 3 As shown, the polishing machine II 202 includes a drive motor II 202a mounted on the mounting plate 103. In addition, a drive wheel II 202b is also mounted on the mounting plate 103, and a driven wheel II 202c is mounted on the fixed plate 102. The drive wheel II 202b and the driven wheel II 202c are connected by a polishing abrasive belt. When the drive motor II 202a works to drive the drive wheel II 202b to rotate, it can drive the polishing abrasive belt to rotate, thereby polishing the aluminum strip.

[0032] In this embodiment, polishing machine I 201 and polishing machine II 202 work simultaneously to polish both sides of the aluminum busbar, thereby ensuring the polishing effect of the aluminum busbar.

[0033] Additionally, it is worth noting that in this embodiment, driven wheel I 201c and driven wheel II 202c are connected to fixed plate 102 and mounting plate 103 respectively via connecting arms. The connecting arms are connected to fixed plate 102 and mounting plate 103 respectively via torsion springs. Furthermore, when the polishing belt is respectively fitted onto driven wheel I 201b and driven wheel I 201c, the torsion spring between the connecting arm on driven wheel I 201c and mounting plate 103 is in a stored state. Therefore, when the polishing belt stretches after prolonged use, the torsion spring can drive the connecting arm to rotate driven wheel I 201c, thereby ensuring that the polishing belt is in a taut state. Similarly, the polishing belt located in polishing machine II 202 can also be kept taut, thus facilitating the grinding and polishing of aluminum bars. Example

[0034] In this embodiment, to prevent damage to the aluminum busbar due to excessive clamping force when the clamping head 303 clamps it, a buffer mechanism is also provided to buffer the clamping force of the clamping head 303. Figures 6-9As shown, the clamping head 303 in this embodiment is composed of a connecting plate 303a and a clamping plate 303b. In this embodiment, the connecting plate 303a is connected to the connecting member 304. Therefore, when the finger cylinder 301 works and drives the connecting member 304 to move, it can drive the connecting plate 303a to move. In addition, the clamping plate 303b is connected to the side wall of the opposite side of the connecting plate 303a by a spring 303c. When the clamping heads 303 work together to clamp the aluminum busbar, the clamping plate 303b contacts the aluminum busbar, causing the spring 303c to compress, thereby playing a certain buffering role on the clamping force of the clamping head 303, avoiding the problem of damage to the aluminum busbar due to excessive clamping force. Therefore, the clamping plate 303b and the spring 303c in this embodiment serve as a buffering mechanism to buffer the clamping force of the clamping head 303 on the aluminum busbar, thereby avoiding damage to the aluminum busbar.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
