DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] Please refer to Figure 1 , Figure 1 A flowchart of a deep hole processing method provided in an embodiment of the present application. The deep hole processing method in the embodiment of the present application can be applied to CNC processing equipment, wherein the CNC processing equipment includes a fixed-point drill, a hole guide drill, a deep hole drill and a drive shaft, wherein the drive shaft is a main shaft or a back shaft, and the fixed-point drill, the hole guide drill and the deep hole drill are fixed to the working surface of the CNC processing equipment, which can be a workbench, a support wall or a tool holder, etc. The product to be processed is clamped and fixed in the center hole of the drive shaft as a whole. Figure 1 As shown, the deep hole processing method of this embodiment includes steps S101 to S104, which are described in detail as follows: Step S101, controlling the driving shaft to rotate, so as to drive the product to be processed to rotate.

[0018] In this step, the driving shaft is installed on the rotating mechanism, the rotating mechanism is connected to the feeding mechanism (such as an XYZ three-axis feeding mechanism or an XY two-axis feeding mechanism), the feeding mechanism drives the rotating mechanism to move, the rotating mechanism drives the driving shaft to rotate, and the driving shaft drives the product to be processed to rotate.

[0019] Step S102, controlling the driving shaft to align with the drill bit of the fixed-point drill, and then moving a first preset distance toward the fixed-point drill, so as to use the fixed-point drill to perform fixed-point processing on the product to be processed, thereby obtaining a fixed-point processed product.

[0020] In this step, the product to be processed is in the center hole of the drive shaft, so the drive shaft is aligned with the drill bit of the fixed-point drill, which means that the product to be processed is aligned with the drill bit of the fixed-point drill. The feed mechanism controls the drive shaft to drive the product to be processed to move toward the fixed-point drill. Since the product to be processed is rotating, when the product to be processed contacts the drill bit of the fixed-point drill, the drill bit will form a fixed-point hole on the product to be processed. It can be understood that since there is a certain distance between the product to be processed and the drill bit before moving the first preset distance, the depth of the fixed-point hole is less than the first preset distance.

[0021] In some embodiments, the step S102 includes: Controlling the drive shaft to be positioned at a first preset position; Controlling the driving shaft to linearly advance to a position corresponding to a fourth preset distance from the fixed-point drill, and then performing positioning verification on the driving shaft and the fixed-point drill; If the positioning check is successful, the drive shaft is continued to be controlled to linearly advance the first preset distance so that the fixed-point drill can locate the product to be processed in the drive shaft, and then the drive shaft is controlled to return to the first preset position to obtain the fixed-point processed product.

[0022] In this embodiment, the first preset position is the position where the product to be processed is aligned with the drill bit of the fixed-spot drill; the positioning verification is to obtain the current drive shaft coordinates (which can be determined according to the feed coordinates of the feed mechanism), and determine whether the alignment between the product to be processed and the drill bit is offset according to the drive shaft coordinates. Since the fixed-spot drill is fixed on the work surface, that is, the position of the fixed-spot drill remains unchanged, if the current drive shaft coordinates are consistent with the preset coordinates, it can be determined that the positioning verification is successful; after the drive shaft returns to the first preset position, the drive shaft is controlled to stop rotating to reduce contact vibration and ensure the processing accuracy of subsequent processing.

[0023] Step S103, controlling the driving shaft to align with the drill bit of the hole-guiding drill, and then moving toward the hole-guiding drill by a second preset distance, so as to use the hole-guiding drill to make a hole in the fixed-point processed product to obtain a hole-guiding processed product.

[0024] In this step, the fixed-point drill is used to determine the drilling position, and the guide hole drill is used to provide a support point when the deep hole drill is working. Therefore, in order to ensure that the guide hole can provide better support, the guide hole has a deeper hole depth than the fixed-point hole, that is, the first preset distance is smaller than the second preset distance.

[0025] In some embodiments, the step S103 includes: Controlling the drive shaft to be positioned at a second preset position; Controlling the driving shaft to linearly advance to a position corresponding to a fourth preset distance from the hole-guiding drill, and then performing positioning verification on the driving shaft and the hole-guiding drill; If the positioning check is successful, continue to control the drive shaft to advance linearly 1 mm each time, and cyclically advance the second preset distance, so that the hole drill can drill a hole in the fixed-point processed product in the drive shaft, and then control the drive shaft to return to the second preset position to obtain the hole-processed product.

[0026] In this embodiment, the second preset position is the position of the product to be processed aligned with the guide hole drill, and the positioning verification process is similar to step S102. Since the depth of the guide hole is deeper than the fixed hole, in order to avoid the eccentricity of the drill bit during the guide hole process, a cyclic advancement method is used for drilling. After advancing 1mm each time, the advancement is stopped for a preset time (such as not advancing within 0.1 seconds), and the second preset distance is advanced in total. After the drive shaft returns to the second preset position, the drive shaft is controlled to stop rotating to reduce contact vibration and ensure the processing accuracy of subsequent processing.

[0027] Step S104, controlling the driving shaft to align with the drill bit of the deep hole drill, and then moving toward the deep hole drill by a third preset distance, so as to perform deep hole processing on the lead hole processing product with the deep hole drill to obtain a deep hole processing product.

[0028] In this step, the second preset distance is smaller than the third preset distance. Optionally, the ratio of the hole depth of the lead hole processing product to the hole depth of the deep hole processing product is 1:10. By using a lead hole with a hole depth one-tenth of the deep hole to provide a support point for the deep hole drill, the deep hole drill can have better stability during operation.

[0029] In some embodiments, the step S104 includes: Starting a high-pressure oil pump and controlling the drive shaft to be positioned at a third preset position, wherein the high-pressure oil pump is used to provide propulsion power for the drive shaft; Controlling the driving shaft to linearly advance to a position corresponding to a fourth preset distance from the deep hole drill, and then performing positioning verification on the driving shaft and the deep hole drill; If the positioning check is successful, continue to control the drive shaft to advance linearly by 1 mm each time, and cyclically advance the third preset distance, so that the deep hole drill performs deep hole processing on the lead hole processing product in the drive shaft, and then control the drive shaft to return to the machine tool origin position, stop the high-pressure oil pump, and obtain the deep hole processing product.

[0030] In this embodiment, the high-pressure oil pump can increase the feed pressure of the drive shaft to cope with the mechanical characteristics during deep hole processing. The third preset position is the position where the product to be processed is aligned with the deep hole drill bit. The positioning verification process is similar to step S102.

[0031] Optionally, the diameter of the guide hole drill is the same as that of the deep hole drill to ensure the concentricity between the guide hole and the deep hole, as well as the concentricity of the hole drilled by the deep hole drill, to avoid the concentricity not meeting the requirements due to the different diameters of the guide hole drill and the deep hole drill.

[0032] Optionally, the material rigidity of the guide hole drill is different from that of the deep hole drill, and the deep hole drill has better material rigidity; the feed pressure corresponding to the guide hole drill is different from that corresponding to the deep hole drill, and the feed pressure corresponding to the deep hole drill is greater.
