Description

Technical Field

[0001] The present invention belongs to the technical field of metal processing, and specifically relates to a grinding machine for grinding metal parts. Background Art

[0002] A grinding machine is a machine tool used for processing metal parts. During the processing of metal parts, the grinding belt in the grinding machine wipes on the surface of the metal parts, thereby achieving the purpose of grinding the metal parts. Therefore, in the technical field of metal part processing, a grinding machine for grinding metal parts is a common processing equipment. The grinding machine is used to grind metal parts to achieve the purpose of processing metal parts.

[0003] Currently, there are various types of grinding machines. For example, Chinese invention patent CN115922467A discloses a surface grinding machine for processing metal parts, which includes a grinding machine frame and a grinding mechanism. The grinding mechanism is located at the upper part of the grinding machine frame, and a bearing plate is movably arranged at the lower part of the grinding machine frame. Protective plates are arranged around the bearing plate, and a water spraying mechanism is arranged on the protective plates. The water spraying mechanism includes a water pipe, a water pump, a connecting pipe and a nozzle. The bearing plate is provided with water permeable holes. One end of the water pipe is connected to the water permeable holes, and the other end is connected to the connecting pipe. The connecting pipe is installed on the inner wall of the protective plate facing the grinding mechanism. When this surface grinding machine works, the metal part is fixed on the bearing plate, and the metal part is ground by the grinding mechanism to achieve the purpose of processing the metal part, and the metal part is processed according to the use requirements to meet the needs of production and processing.

[0004] Although the above-mentioned surface grinding machine can achieve the processing of metal parts, there are still certain defects in the actual use process of the above-mentioned surface grinding machine. When the grinding wheel in the grinding mechanism is used for a long time, the grinding wheel is prone to loosen. When the grinding wheel is loose, it is impossible to effectively grind the metal parts. Since the grinding machines in the prior art do not have an adjustment mechanism to adjust the tightness of the grinding wheel, the stable state of the grinding wheel cannot be guaranteed, and thus a high-quality grinding effect cannot be guaranteed.

[0005] Therefore, the present invention provides a grinding machine for grinding metal parts, which can adjust the tightness of the grinding assembly to ensure the grinding effect on the metal parts. Summary of the Invention

[0036] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings of the specification.

[0037] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Persons skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0038] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other with other embodiments. The present invention provides the following embodiments.

[0039] As Figure 1 、 Figure 2 and Figure 3 shown, it is a schematic structural diagram of a grinding machine for grinding metal parts in this embodiment. The grinding machine in this embodiment includes a loading box. A loading table 101 is installed on the loading box, and a grinding mechanism 200 is also installed on the surface of the loading box. In this embodiment, the metal part is installed on the loading table 101, and the surface of the metal part is ground by the grinding mechanism 200 to achieve the processing purpose of the metal part.

[0040] In this embodiment, as Figure 3 and Figure 4 shown, a clamping mechanism 102 is further provided on the loading table 101. The clamping mechanism 102 includes a rotating shaft 102a and a clamping plate 102d. In this embodiment, the rotating shaft 102a is installed on the loading table 101, and the loading table 101 is fixedly connected to the rotating shaft 102a. When the rotating shaft 102a rotates, it can drive the loading table 101 to rotate synchronously. In this embodiment, the clamping plate 102d is slidably installed on the rotating shaft 102a. After the metal part is placed on the loading table 101, the clamping plate 102d moves downward and presses against the metal part, thereby pressing the metal part tightly on the loading table 101.

[0041] As Figure 4As shown in the figure, in this embodiment, an external thread is further provided on the rotating shaft 102a. A threaded sleeve 102b is threadedly connected to the rotating shaft 102a. A compression spring 102c is installed between the threaded sleeve 102b and the clamping plate 102d. In this embodiment, when the threaded sleeve 102b moves downward, the clamping plate 102d is driven by the compression spring 102c to move downward to press the metal part on the surface of the bearing table 101. In this embodiment, when the metal part is pressed, the compression spring 102c is in a compressed state, and the metal part is pressed by the pressure of the compression spring 102c. Moreover, when the rotating shaft 102a rotates, it drives the bearing table 101 and the metal part to rotate synchronously. It should be noted that the metal part in this embodiment has a concentric circle structure, is sleeved on the rotating shaft 102a and located on the surface of the bearing table 101, and then the clamping plate 102d, the compression spring 102c and the threaded sleeve 102b are installed to press and fix the metal part.

[0042] As Figure 5 shown, the grinding machine in this embodiment further includes a driving mechanism 100 for driving the bearing table 101 to rotate. The driving mechanism 100 is installed in the bearing box. In this embodiment, the rotating shaft 102a passes through the bearing table 101 and enters the bearing box. A driving motor is installed in the bearing box. A transmission wheel is installed at the power end of the driving motor. The transmission wheel is connected to an installation wheel through a belt drive, and the installation wheel is installed on the rotating shaft 102a. In this embodiment, when the driving motor works, it drives the transmission wheel to rotate. During the rotation of the transmission wheel, the installation wheel is driven by the belt to rotate, and thus the rotating shaft 102a and the bearing table 101 can be driven to rotate synchronously.

[0043] As Figure 5 shown, in order to ensure the stability of the driving mechanism 100 when driving the rotating shaft 102a to rotate, in this embodiment, a fixing plate 103a is installed in the bearing box, and the driving motor is installed on the fixing plate 103a. Moreover, a spring is installed between the fixing plate 103a and the side wall of the bearing box. The purpose of setting the spring is to avoid the rigid collision between the fixing plate 103a and the side wall of the bearing box caused by the operation of the driving motor, and to ensure the working effect of the driving motor.

[0044] In this embodiment, as Figure 7 and Figure 8 shown, in this embodiment, a grinding mechanism 200 is further installed on the surface of the bearing box. The grinding mechanism 200 is used to grind the metal part on the surface of the bearing table 101. In this embodiment, the grinding mechanism 200 includes a telescopic driver 201 installed on the surface of the bearing box. A fixing frame 202 is installed at the power end of the telescopic driver 201. A grinding motor is also installed on the fixing frame 202. A driving roller 203 is installed at the power end of the grinding motor. In this embodiment, as Figure 8As shown, a rotating plate 206 is also rotatably mounted on the fixing frame 202 in this embodiment. A driven roller 204 is rotatably mounted on the rotating plate 206. In this embodiment, the driving roller 203 and the driven roller 204 are connected by a grinding sand belt for transmission. In this embodiment, when the grinding motor works, it drives the driving roller 203 to rotate. The driving roller 203 drives the driven roller 204 to rotate through the grinding sand belt. During the rotation of the grinding sand belt, the metal parts on the surface of the bearing table 101 are ground, ensuring the grinding effect on the metal parts.

[0045] As Figure 7 shown, in this embodiment, in order to ensure that the grinding sand belt can stably contact the metal parts to ensure the grinding effect on the metal parts, in this embodiment, a slide rail is installed on the fixing frame 202. A slider is installed on the slide rail, and a pressing plate 205 is connected to the slider. Moreover, a telescopic spring is also connected between the fixing frame 202 and the slider. In this embodiment, the telescopic spring is in a compressed state. Therefore, the telescopic spring can drive the slider to drive the pressing plate 205 to move downward until the pressing plate 205 presses the grinding sand belt against the surface of the metal parts. Therefore, the grinding sand belt can stably grind the metal parts during the rotation process.

[0046] In this embodiment, when the grinding motor works, it drives the driving roller 203 to rotate, thereby driving the grinding sand belt to rotate. Due to the action of the pressing plate 205, the grinding sand belt is always pressed against the metal parts. The rotating grinding sand belt grinds the surface of the metal parts, ensuring the grinding efficiency.

[0047] As Figure 8 shown, in this embodiment, in order to ensure that the grinding sand belt is always in a taut state to ensure the grinding effect, in this embodiment, the rotating plate 206 is rotatably mounted on the back of the fixing frame 202. In this embodiment, a spring is also connected between the end of the fixing frame 202 and the rotating plate 206. The spring is in a stretched state. The elastic force of the spring drives the rotating plate 206 to have a tendency to rotate, thereby driving the driven roller 204 to have a tendency to rotate outward. Therefore, through the mutual cooperation of the driven roller 204 and the driving roller 203, the grinding sand belt is always in a taut state, facilitating the grinding of the metal parts.

[0048] In this embodiment, through the pulling of the spring, the driven roller 204 always has a tendency to rotate outward, thereby driving the driven roller 204 to have a tendency to rotate outward. The mutual cooperation of the driven roller 204 and the driving roller 203 tightens the grinding sand belt. The grinding sand belt is in a taut state during the rotation process to grind the metal parts, ensuring the grinding effect.

[0049] As Figure 3 and Figure 6As shown in the figure, in this embodiment, an adjusting mechanism 300 is further installed on the surface of the carrying box. The adjusting mechanism 300 is used to ensure that the carrying platform 101 rotates stably, avoiding the problem that the carrying platform 101 swings due to loosening.

[0050] In this embodiment, a driven wheel 304 is rotatably installed on the surface of the carrying box through a bracket, and a support frame 301 is fixedly installed on the surface of the carrying box. An adjusting wheel 303 is installed on the support frame 301. The adjusting wheel 303, the driven wheel 304, and the carrying platform 101 are connected by a transmission belt. In this embodiment, during the rotation of the carrying platform 101, the transmission belt is driven. During the transmission of the transmission belt, the adjusting wheel 303 and the driven wheel 304 are driven to rotate. In this embodiment, the transmission belt is assembled on the side of the carrying platform 101, and the problem that the carrying platform 101 swings is avoided during the transmission of the transmission belt.

[0051] In this embodiment, in order to ensure that the transmission belt is always in a taut state to ensure the stable effect of the carrying platform 101, as Figure 6 shown, in this embodiment, a rotating frame 302 is rotatably installed on the support frame 301. The adjusting wheel 303 is rotatably installed at one end of the rotating frame 302. A spring is installed between the other end of the rotating frame 302 and the support frame 301. The spring is in a stretched state. Due to the pulling force of the spring, the rotating frame 302 is driven to rotate. During the rotation of the rotating frame 302, the adjusting wheel 303 is driven to move, so that the transmission belt between the adjusting wheel 303, the carrying platform 101, and the driven wheel 304 is in a taut state. In this embodiment, after the transmission belt is taut, it always presses against the side of the carrying platform 101, avoiding the problem that the carrying platform 101 swings due to loosening, thus ensuring the stable effect of the carrying platform 101.

[0052] In this embodiment, the metal piece is sleeved on the rotating shaft 102a on the surface of the carrying platform 101. Through the action of the clamping plate 102d and the compression spring 102c, the clamping plate 102d presses against the surface of the metal piece, thus ensuring the stability of the metal piece on the surface of the carrying platform 101. The grinding motor in the grinding mechanism 200 works to drive the driving roller 203 to rotate, thereby driving the grinding sand belt to rotate. The grinding sand belt is in a taut state due to the action of the driven roller 204, and the grinding sand belt always presses against the surface of the metal piece due to the action of the pressing plate 205. During the rotation of the grinding sand belt, the surface of the metal piece is ground, ensuring the grinding effect.

[0053] In this embodiment, in order to ensure the stable effect of the carrier table 101, the spring in the adjusting structure 300 acts to drive the adjusting wheel 303 to move, so that the transmission belt between the carrier table 101, the adjusting wheel 303 and the driven wheel 304 is in a taut state, ensuring the transmission rotation effect of the carrier table 101, facilitating the grinding of metal parts and ensuring the grinding quality of metal parts.

[0054] The above content is a further detailed description of the present invention in combination with specific embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope determined by the claims submitted for the present invention.
