Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a honing machine. Background Technology

[0002] Currently, due to the high precision requirements for hole machining of mechanical parts, multiple honing processes are needed to improve product accuracy. This requires multiple honing machines to be connected in series to perform multiple honing processes. However, multiple clamping can easily increase machining errors, and multiple honing machines connected in series occupy a large area, prolong the production cycle, and reduce production efficiency. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a honing machine that reduces the number of clamping operations, processes multiple holes simultaneously, and can effectively perform real-time detection.

[0004] To solve the above-mentioned technical problems, one technical solution adopted by the present invention is: to provide a honing machine, including a machine tool body, a base disposed on one side of the machine tool body, a positioning mechanism and a clamping device disposed on the base for limiting the workpiece, and a grinding head assembly disposed on the other side of the machine tool body, wherein a transfer mechanism for moving the workpiece is provided on the machine tool body at a position corresponding to the position between the base and the grinding head assembly; and a detection mechanism is also provided on the machine tool body.

[0005] Using the above structure, a positioning mechanism and a clamping device are set up to assist in the clamping and positioning of the workpiece. The grinding head group hones multiple holes on the workpiece simultaneously, and the transfer mechanism moves the workpiece out horizontally. Then, the workpiece is quickly rotated 180° and moved back to the base. The machined position is matched and positioned by the corresponding position of the positioning mechanism, and the clamping device performs secondary clamping. The grinding head group hones multiple holes on the workpiece simultaneously until the holes are machined. Finally, the transfer mechanism clamps the workpiece from the base and transfers it to the detection mechanism for measurement. The entire process involves only two clamping operations, reducing clamping errors. The two-stage machining of holes avoids the situation where the machining accuracy is inconsistent due to the long single-sided machining distance. Simultaneous machining of multiple holes also improves production efficiency. The detection mechanism can promptly reflect the machining status, which facilitates timely adjustment of displacement and positioning parameters, and can promptly remind you to change tools to prevent batch machining accidents.

[0030] The machine tool body 1 is also provided with an air jet pipe 91 that is connected to an air pump (not shown) and used to remove residues on the base 2; a guide rail 12 is fixed on the machine tool body 1, and a drive motor 14 connected to a PLC controller is provided on one side of the guide rail 12. The output end of the drive motor 14 is screwed to the tailstock 10. A guide rod 13 fixed on the machine tool body 1 is provided on one side of the tailstock. A sliding groove is provided at the lower end of the tailstock 10 corresponding to the position of the guide rail 12, and the guide rail 12 slides in the sliding groove.

[0031] The working principle of this invention is as follows: like Figures 1 to 5 As shown, taking the simultaneous processing of three-hole parts as an example, the workpiece is first clamped by the upper clamping plate 71 and the lower clamping plate 72 at the output end of the robotic arm 7. The upper bending section 711 and the lower bending section 721 respectively abut against the arc part of the corresponding position on the outside of the workpiece to ensure the stability of the workpiece clamping. The PLC controller first starts the transmission motor 14, which drives the tailstock 10 to slide along the guide rail 12 along the guide rod 13 to the standby position on the machine tool body 1.

[0032] The clamped workpiece is moved to position 2 of the base, and the end face of one end of the workpiece hole abuts against the outer surfaces of the first annular boss 31, the second annular boss 32, and the third annular boss 33, respectively. At the same time, the corresponding first positioning block 21, the second positioning block 22, and the third positioning block 23 extend into the corresponding holes of the workpiece. At this time, the PLC controller simultaneously activates the first corner-pressing cylinder 51 and the second corner-pressing cylinder 52, and the clamping blocks 56 connected to the output ends of the two corner-pressing cylinders abut against and clamp the workpiece. Figure 2 At the corresponding position on the outer wall of the workpiece (at the position of the dashed line), the limiting groove 57 is engaged with the groove in the middle of the workpiece. Figure 2 At the edge of the middle of the dashed line (such as...) Figure 5 (as shown in the diagram) Then, the upper clamping plate 71 and the lower clamping plate 72 release the workpiece, and the robotic arm 7 drives the upper clamping plate 71 and the lower clamping plate 72 away from the position of the base 2; then, the PLC controller simultaneously starts the first linear motor 60 and the power motor 61 at the corresponding position of the hole, driving the honing block 62 to perform honing on the hole.

[0033] After a certain stroke, the first linear motor 60 drives the base plate 6 to move back, which in turn drives the honing block 62 to move back simultaneously. At this time, the robotic arm 7 is activated to move the upper clamping plate 71 and the lower clamping plate 72 to the position of the base 2 and clamp the workpiece in the loading state. Immediately afterwards, the two corner pressing cylinders are activated to drive the clamping block 56 away from the workpiece. Then, the robotic arm 7 moves the workpiece horizontally away from the base 2. Then, the workpiece is rotated 180° in the vertical direction, that is, the end with the machined hole faces the base 2, and the workpiece is then moved onto the base 2. At this time, since the axis center lines of the third positioning block 23 and the fourth positioning block 24 are set parallel to each other and arranged in a first ring shape... The axis connecting the boss 31 and the second annular boss 32 is centrally symmetrically arranged. Combined with the increased size of the machined hole position, when the workpiece is clamped and positioned again, the hole position of the workpiece is respectively fitted on the outer wall of the first positioning boss 41, the second positioning boss 42 and the fourth positioning block 24. Then, the PLC controller simultaneously starts the first corner pressing cylinder 51 and the second corner pressing cylinder 52, and makes the clamping block 56 connected to the output end of the two corner pressing cylinders abut against the corresponding position of the outer wall of the workpiece. Then, the upper clamping plate 71 and the lower clamping plate 72 release the workpiece, and the robotic arm 7 drives the upper clamping plate 71 and the lower clamping plate 72 away from the position of the base 2.

[0034] Finally, the PLC controller simultaneously starts the first linear motor 60 and the power motor 61 corresponding to the hole position, driving the honing block 62 to hone the remaining position of the hole. After processing, the robotic arm 7 drives the upper clamping plate 71 and the lower clamping plate 72 to clamp the workpiece and move it to the position of the fixed plate 11. At this time, the mounting plate 84 is equipped with three detection plugs 85 for the three processed holes, and three infrared diameter gauges 86 (e.g., ...) set concentrically. Figure 4 (Setting status shown).

[0035] At this point, the robotic arm 7 rotates the workpiece to a horizontal position, that is, the hole opening is positioned with the upper and lower ends facing each other. The second servo motor 82 is activated, causing the detection block 85 to rotate to one side of the horizontal axial position corresponding to the hole, that is, the longitudinal projection of the axial center line of the detection block 85 coincides with the axial center line of the corresponding hole. Next, the first servo motor 81 is activated to drive the connecting block 8 to move horizontally, simultaneously driving the connecting plate 83 to move horizontally along the axial direction of the clearance groove, that is, driving the detection block 85 to stop directly above the hole to be inspected. Then, the second linear motor 9 is activated to move the fixing plate 11, that is, simultaneously driving the detection block 85 to move towards the hole to be inspected. Since the detection block 85 is set to a gauge size, it only needs to be inserted into the machined hole. After this inspection is completed, the second linear motor 9... The machine 9 drives the detection plug (85) to move out of the hole to be tested, then starts the second servo motor 82, rotates the mounting plate 84, and moves the infrared diameter gauge (86), which is concentrically set with the corresponding detection plug 85 (centered on the connection position between the mounting plate 84 and the second servo motor 82), directly above the hole to be tested. The infrared gauge is used to detect whether the processing dimension exceeds the tolerance based on the test of the go gauge dimension. If it is within the range of the no-go gauge test dimension (lower limit processing dimension), it is qualified. If it exceeds the no-go gauge test dimension (upper limit processing dimension), it is unqualified. At the same time, the test data is transmitted back to the PLC controller. Based on the test results, the PLC controller sends the instruction to the connected relevant components to continue processing or stop processing. After the test is completed, the second servo motor 82 drives the mounting plate 84 back to the standby position to prevent the connecting wires from rotating and getting tangled.

[0036] It should be noted that in order to ensure the concentricity of the secondary clamping (i.e., to ensure that there is no offset interference with the positioning block during the secondary clamping), the robotic arm 7 must remain horizontal when moving the workpiece out. In addition, since the part is placed on the vertically placed base 2, a positioning block is required for limiting, and through-hole machining cannot be achieved in one go. Therefore, two hole machining operations are performed. In the first machining operation, the workpiece abuts against three annular bosses, which is equivalent to lifting the workpiece on the horizontal plane, increasing the depth of the first hole machining (i.e., more than half the hole depth). In the second machining operation after flipping the workpiece, the workpiece abuts against the base 2 and is positioned by the positioning bosses at the corresponding hole positions and the outer wall of the fourth positioning block 24. At this time, the hole is honing and machined from the other end of the hole position. Therefore, in order to avoid machining interference, the thickness of the positioning block should also be less than half the hole depth to facilitate a complete joint between the two hole machining strokes.

[0037] In addition, for workpieces with different shapes and specifications, the clamping block 56 can be moved axially along the strip groove 54 by the connecting rod and riveted and positioned by the locking nut 55 to adjust the clamping position of the clamping block 56. For workpieces without a central groove, the clamping block 56 without the limiting groove 57 can also be selected, making it flexible to use.

[0038] In addition, when the workpiece is flipped, the PLC controller starts the air pump and air is sprayed from the air jet pipe 91 to the base 2 to remove the processing waste residue on the base 2. For multi-hole positions, multiple air distribution pipes should be connected to the outlet end of the air jet pipe 91. The specific requirements depend on the actual processing needs and will not be elaborated here.

[0039] If the workpiece has only two holes, then any two of the four positioning blocks can be screwed and installed on the base 2 in any combination (such as installing only the first positioning block 21 and the second positioning block 22), or a base 2 with only two holes needs to be machined can be set up. The machining steps are as described above and will not be repeated here.

[0040] This processing method not only reduces the number of clamping operations while ensuring the quality of hole machining, but also avoids affecting the machining quality of the hole wall by using the annular boss set for secondary positioning based on changes in machining dimensions. In addition, when checking dimensions, the hole size is checked using a go gauge. At the same time, in order to avoid the obstruction effect of the no-go gauge, the dimensions are checked again using infrared light after the go gauge has passed through the machined hole position, which acts as a no-go gauge, reducing workpiece collisions and improving measurement accuracy.
