Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a machining device. Background Technology

[0002] Because commercially available grinding wheels have relatively uniform sizes and profiles, which do not meet the requirements of product processing, operators must use a dressing pen punch on a hand-cranked forming grinder to dress the profile of the grinding wheel before processing, so that the grinding wheel can accurately process the workpiece. However, manual dressing has low precision, which in turn reduces the processing accuracy of the product. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0042] Please see Figure 1 and Figure 2 This application provides a processing apparatus 100, which includes a processing spindle 10, a processing component 20, a dressing component 30, and a controller 40. The processing apparatus 100 is used to process a workpiece 200 to improve the processing accuracy of the workpiece 200. In this embodiment, the workpiece 200 is a medical device clamping component. The workpiece 200 includes a cutting tool 202, which is clamped to the medical device clamping component. The medical device clamping component has a guide groove 201, which is formed on the surface of the medical device clamping component and extends to the end of the cutting tool 202. The guide groove 201 guides the processing component 20 to move to the end of the cutting tool 202 for precise processing of the cutting tool 202. Exemplarily, the cutting tool 202 is a cutting blade of a laparoscopic anastomosis device.

[0043] Please see Figure 1 and Figure 3 The machining assembly 20 includes a connector 21, a roughing component 22, and a finishing component 23. The connector 21 is detachably connected to the machining spindle 10. The roughing component 22 and the finishing component 23 are spaced apart and connected to the connector 21 respectively. The roughing component 22 and the finishing component 23 are used to process the workpiece 200 in sequence.

[0044] The dressing assembly 30 includes a drive member 31 and a dressing member 32. The drive member 31 is disposed on one side of the machining spindle 10 and connected to the dressing member 32. The controller 40 is electrically connected to the machining spindle 10 and the drive member 31 respectively. The controller 40 is used to control the machining spindle 10 to drive the roughing workpiece 22 and the finishing workpiece 23 to move relative to the dressing member 32, and to control the drive member 31 to drive the dressing member 32 to rotate, so that the dressing member 32 sequentially dresses the roughing workpiece 22 and the finishing workpiece 23. For example, the machining spindle 10 can be a machine tool spindle.

[0045] In actual use, the aforementioned processing device 100 firstly drives the processing spindle 10 to move the rough-machined part 22 and the finishing part 23 relative to the trimming part 32, and controls the drive component 31 to drive the trimming part 32 to rotate, so that the trimming part 32 sequentially trims the rough-machined part 22 and the finishing part 23 to a preset contour; then, the controller 40 drives the processing spindle 10 to move the trimmed rough-machined part 22 and the finishing part 23 closer to the workpiece 200; finally, the controller 40 drives the processing spindle 10 to sequentially process the workpiece 200 with the rough-machined part 22 and the finishing part 23. Thus, by controlling the processing spindle 10 to move the rough-machined part 22 and the finishing part 23 relative to the spindle, and controlling the drive component 31 to drive the trimming part 32 to rotate, precise and rapid trimming of the rough-machined part 22 and the finishing part 23 is achieved, avoiding manual trimming of the rough-machined part 22 and the finishing part 23, improving trimming accuracy, and thus improving processing accuracy.

[0046] Please see Figure 4 In some embodiments, the connector 21 includes a connector 211, an adjusting body 212, and a locking body 213. The connector 211 is detachably connected to the machining spindle 10. The roughing part 22 and the finishing part 23 are spaced apart on the connector 211 along the direction from the connector 211 toward the machining spindle 10. The adjusting body 212 is fitted onto the connector 211, with its two sides abutting against the roughing part 22 and the finishing part 23, respectively. The adjusting body 212 is used to adjust the distance between the roughing part 22 and the finishing part 23. The locking body 213 is detachably connected to the end of the connector 211 away from the machining spindle 10 and abuts against the roughing part 22. The locking body 213 is used to lock the roughing part 22 and the finishing part 23 to the connector 211.

[0047] Thus, by setting the specific structure of the connecting member 21, the adjusting body 212 adjusts the distance between the rough-machined part 22 and the finishing part 23 so that the rough-machined part 22 and the finishing part 23 maintain a preset distance, which is beneficial for the rough-machined part 22 and the finishing part 23 to process the workpiece 200 in sequence. The locking body 213 is detachably connected to the connecting body 211 and abuts against the rough-machined part 22, so that the rough-machined part 22, under the push of the locking body 213, presses the finishing part 23 against the side of the connecting body 211 away from the machining spindle 10 through the adjusting body 212. This realizes that the locking body 213 locks the rough-machined part 22 and the finishing part 23 to the connecting body 211, preventing the rough-machined part 22 and the finishing part 23 from shaking during the trimming or processing, and ensuring trimming accuracy and processing accuracy.

[0048] It is understood that the adjusting body 212 can be any adjusting part, adjusting block, or similar adjusting element capable of adjusting the distance between the rough-machined part 22 and the finish-machined part 23. The number of adjusting bodies 212 can be multiple. The distance between the rough-machined part 22 and the finish-machined part 23 can be adjusted by increasing or decreasing the number of adjusting bodies 212 according to usage requirements. Here, "multiple" refers to two or more.

[0049] Please see Figure 4 In some embodiments, the connector 211 includes a main body 2111 and a connecting portion 2112. The main body 2111 is detachably connected to the machining spindle 10. The connecting portion 2112 protrudes from the end of the main body 2111 opposite to the machining spindle 10. The connecting portion 2112 passes through the finishing part 23, the adjusting body 212, and the roughing part 22. The end of the connecting portion 2112 away from the main body 2111 is detachably connected to the locking body 213. The connector 21 also includes an abutment 214, which is sleeved on the connecting portion 2112. The two sides of the abutment 214 abut against the finishing part 23 and the main body 2111, respectively, to isolate the main body 2111 and the finishing part 23.

[0050] Thus, by setting the two sides of the abutment 214 to abut against the precision-machined part 23 and the main body 2111 respectively, the main body 2111 and the precision-machined part 23 are separated, preventing slippage between the main body 2111 and the precision-machined part 23, and ensuring that the main body 2111 stably drives the precision-machined part 23 to rotate synchronously through the connecting part 2112.

[0051] The cross-sectional area of ​​the main body 2111 is larger than that of the connecting part 2112, so that the main body 2111 supports the precision-machined part 23, the adjusting part 212 and the rough-machined part 22 through the abutment body 214, and the locking body 213 locks the rough-machined part 22 and the precision-machined part 23 to the connecting part 2112.

[0052] Please refer to it again. Figure 4 In some embodiments, the peripheral side of the end of the connecting part 2112 away from the main body 2111 is provided with a retaining groove 2113. The locking body 213 includes an abutting part 2131, a retaining part 2132 and a locking part 2133. The abutting part 2131 is sleeved on the connecting part 2112 and abuts against the rough-machined part 22. The retaining part 2132 is sleeved on the connecting part 2112 and abuts against the abutting part 2131. The retaining part 2132 is engaged with the retaining groove 2113. The locking part 2133 is sleeved on the connecting part 2112 and threadedly connected to the connecting part 2112. The locking part 2133 is used to press the abutting part 2131 against the rough-machined part 22 to lock the rough-machined part 22 and the fine-machined part 23.

[0053] Thus, by setting the abutting part 2131 to abut against the rough-machined part 22 and setting the retaining part 2132 to retain and connect with the retaining groove 2113, the locking part 2133 and the rough-machined part 22 are separated, avoiding direct contact between the locking part 2133 and the rough-machined part 22 and slippage, thereby ensuring that the locking part 2133 stably locks the rough-machined part 22 and the finished part 23 to the connecting part 2112.

[0054] In some embodiments, the hardness of both the rough-machined part 22 and the finish-machined part 23 is less than the hardness of the dressing part 32. For example, the rough-machined part 22 and the finish-machined part 23 can be grinding wheels, and the dressing part 32 can be a diamond roller.

[0055] In this way, by setting the hardness of both the rough-machined part 22 and the fine-machined part 23 to be less than the hardness of the trimming part 32, it is ensured that the trimming part 32 can stably trim the rough-machined part 22 and the fine-machined part 23, avoiding the trimming part 32 from breaking during the trimming operation due to its low hardness, which is beneficial to improving the trimming quality and service life of the trimming part 32.

[0056] Please see Figure 1 In some embodiments, the processing apparatus 100 further includes a detection component 50, which includes a slider 51 and a detection component 52. The slider 51 is disposed on one side of the processing spindle 10 and slidably connected to the processing spindle 10 in the direction pointing from the processing spindle 10 to the connector 21. The detection component 52 is disposed on the side of the slider 51 away from the processing spindle 10 and connected to the slider 51. The detection component 52 is used to slide along the direction pointing from the processing spindle 10 to the connector 21 under the drive of the slider 51 to detect different processing areas of the workpiece 200. Exemplarily, the slider 51 can be any sliding part, sliding body, or similar sliding block capable of driving the detection component 52 to slide, such as a sliding plate connected to a cylinder. The detection component 52 can be any detection part, detection body, or similar detection rod capable of detecting the workpiece 200, such as a detection probe.

[0057] Thus, by setting the specific structure of the detection component 50, the sliding component 51 drives the detection component 52 to slide, so that the detection component 52 detects different processing areas of the workpiece 200 to determine the processing area position of the workpiece 200. Then, the machining spindle 10 drives the roughing component 22 and the finishing component 23 to process the processing area in sequence based on the detection information of the detection component 52, which is beneficial to improving the processing accuracy.

[0058] It is understood that the processing area of ​​the workpiece 200 is the end of the cutting tool 202. In this embodiment, the workpiece 200 includes multiple cutting tools 202, and the medical device clamping component is provided with multiple guide grooves 201, which correspond one-to-one with the multiple cutting tools 202. Thus, by placing the detection element 52 on the side of the sliding member 51 away from the machining spindle 10, the detection element 52 directly corresponds to the processing area. The sliding member 51 drives the detection element 52 to move along the machining spindle 10 towards the connecting member 21, so that the detection element 52 can quickly detect different processing areas of the workpiece 200, which is beneficial to improving detection efficiency. At the same time, it is convenient for the roughing part 22 and the finishing part 23 to extend into the assembly groove 201 to process the workpiece 200.

[0059] Please see Figure 1 and Figure 5 In some embodiments, the machining apparatus 100 further includes a cooling assembly 60 disposed adjacent to the machining spindle 10 and electrically connected to the controller 40, the cooling assembly 60 being used to spray coolant toward the roughing workpiece 22 and the finishing workpiece 23. Exemplarily, the coolant may be water.

[0060] Thus, by setting the aforementioned cooling component 60, the cooling component 60 sprays coolant toward the rough-machined part 22 and the finish-machined part 23, thereby reducing the high temperature generated by the rough-machined part 22 and the finish-machined part 23 when machining the workpiece 200, avoiding damage to the rough-machined part 22, the finish-machined part 23 and the workpiece 200 being machined, which is beneficial to improving the machining quality of the workpiece 200, and at the same time increasing the service life of the rough-machined part 22 and the finish-machined part 23.

[0061] Please see Figure 5 In some embodiments, the cooling assembly 60 includes a coolant supply 61, a coolant spraying component 62, and a first sensor 63. The coolant supply 61 is adjacent to the machining spindle 10 and electrically connected to the controller 40. The coolant supply 61 provides coolant. The coolant spraying component 62 communicates with the coolant supply 61 and is electrically connected to the controller 40. The coolant spraying component 62 sprays coolant toward the roughing workpiece 22 and the finishing workpiece 23. The first sensor 63 is located on one side of the machining spindle 10 and electrically connected to the controller 40. The first sensor 63 detects the machining temperature of the roughing workpiece 22 and the finishing workpiece 23. Exemplarily, the coolant spraying component 62 can be any spray section, spray bar, or similar liquid spray capable of spraying coolant, such as a liquid nozzle. The first sensor 63 can be a temperature sensor.

[0062] Thus, the processing temperature of the rough-machined part 22 and the finish-machined part 23 is detected by the first sensor 63. When the processing temperature reaches the preset temperature, the first sensor 63 sends an electrical signal to the controller 40. The controller 40 controls the spraying component 62 to spray the coolant provided by the supply component 61 onto the rough-machined part 22 and the finish-machined part 23 based on the detection information of the first sensor 63, so as to reduce the processing temperature of the rough-machined part 22 and the finish-machined part 23 and ensure the processing quality of the workpiece 200.

[0063] Please see Figure 5 In some embodiments, the liquid supply unit 61 includes a collection body 611, a cooling body 612, and a filter body 613. The collection body 611 is located below the processing assembly 20 and is used to collect coolant that slides from the rough-processed part 22 and the finishing part 23. The cooling body 612 is in communication with the collection body 611 and electrically connected to the controller 40, and is used to cool the coolant collected by the collection body 611. The filter body 613 is in communication with both the cooling body 612 and the spraying part 62, and is used to filter the coolant to provide coolant to the spraying part 62. Exemplarily, the collection body 611 can be any collection section, collection element, or similar collection block capable of collecting coolant, such as a collection box; the cooling body 612 can be any cooling section, cooling block, or similar cooling plate capable of cooling the collected coolant, such as a compressor; and the filter body 613 can be any filter section, filter plate, or similar filter plate capable of filtering coolant, such as a filter plate composed of a coarse filter and a fine filter.

[0064] Thus, by setting the specific structure of the liquid supply component 61, the collecting body 611 first collects the coolant that slides down from the rough-machined part 22 and the fine-machined part 23, then the cooling body 612 cools the collected coolant, and finally the filtering body 613 filters the cooled coolant and then provides the filtered coolant to the spraying component 62, thereby realizing the recycling of coolant and reducing the cost of use.

[0065] Please continue reading. Figure 5 In some embodiments, the cooling assembly 60 further includes a second sensor 64, which is located at the end of the spray nozzle 62 away from the liquid supply nozzle 61 and is electrically connected to the controller 40. The second sensor 64 is used to detect the coolant flow rate information of the spray nozzle 62.

[0066] Thus, by setting the second sensor 64 mentioned above, the second sensor 64 detects the coolant flow information of the spray component 62, so that the controller 40 adjusts the spraying speed of the spray component 62 based on the detection information of the second sensor 64, ensuring that the coolant stably cools the rough-machined part 22, the fine-machined part 23 and the workpiece 200.

[0067] The working process of the aforementioned processing device 100 is roughly as follows:

[0068] First, the controller 40 drives the machining spindle 10 to move the rough workpiece 22 and the finish workpiece 23 relative to the trimmer 32, and controls the drive component 31 to drive the trimmer 32 to rotate, so that the trimmer 32 trims the rough workpiece 22 and the finish workpiece 23 to the preset contour in sequence, thereby achieving precise and fast trimming of the rough workpiece 22 and the finish workpiece 23, avoiding manual trimming of the rough workpiece 22 and the finish workpiece 23, improving trimming accuracy, and thus improving machining accuracy;

[0069] Then, the controller 40 drives the machining spindle 10 to move the rough-machined part 22 and the fine-machined part 23 closer to the workpiece 200. The controller 40 then drives the machining spindle 10 to move the rough-machined part 22 and the fine-machined part 23 to process the workpiece 200 in sequence.

[0070] Finally, the processing temperature of the rough-machined part 22 and the finish-machined part 23 is detected by the first sensor 63. When the processing temperature reaches the preset temperature, the first sensor 63 sends an electrical signal to the controller 40. Based on the detection information of the first sensor 63, the controller 40 controls the spraying component 62 to spray the coolant provided by the supply component 61 onto the rough-machined part 22 and the finish-machined part 23 to reduce the processing temperature of the rough-machined part 22 and the finish-machined part 23 and ensure the processing quality of the workpiece 200.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
