The number of induction coils is the same as the number of shaft parts. Step 2: First, insert the connecting ends of the induction coil into the corresponding Huff grooves of the Huff clamp in sequence, so that the induction ends of the induction coils are parallel to each other on the vertical plane, and then fix the insulating sheet between the connecting ends of two adjacent induction coils, and then align the Huff hole of the Huff clamp with the busbar hole on the busbar, and then insert the fixing screws into the Huff hole and the busbar hole in sequence. At this time, the inner wall of the Huff groove moves toward the center of the Huff groove to clamp all the connecting ends. At the same time, the Huff clamp is fixed to the busbar, and then the plate insulating sheet is fixed on the side of the busbar away from the Huff clamp, and then the connecting plate vertically connected to the busbar is connected to the induction equipment; The third step: first insert the shaft parts into the sensing end one by one, so that there is a certain gap between the outer surface of the shaft parts and the inner surface of the sensing end, and then fix the shaft parts; then move the sensing end back and forth along the axis direction of the shaft parts, and at the same time, let the induction device pass alternating current into the connecting plate, and then the alternating current flows to the busbar and the half clamp in turn, and then flows to each connecting end, and then flows to each sensing end, and each sensing end generates an alternating magnetic field, and then the alternating magnetic field generates an induced current on the surface of the shaft parts, and the induced current generates heat to heat the surface of the shaft parts to complete the heating stage in induction quenching.

[0007] In the second step, inserting the connection ends of the induction coil into the corresponding Haff grooves of the Haff clamps in sequence is inserting one connection end of the induction coil into the first Haff groove of the first Haff clamp in sequence, and then inserting the other connection end of the induction coil into the second Haff groove of the second Haff clamp in sequence; The method of aligning the Huff hole of the Huff clamp with the confluence hole on the confluence plate is to first align the first Huff hole of the first Huff clamp with the first confluence hole on the first confluence plate, and then align the second Huff hole of the second Huff clamp with the second confluence hole on the second confluence plate; The plate insulating sheet is fixed on a side of the busbar away from the half clamp, which is a fixing plate insulating sheet between the first busbar and the second busbar.

[0008] In the second step, the connecting ends of the induction coils are sequentially inserted into the Hough grooves of the corresponding Hough clamps by first inserting the first connecting end of the first induction coil into the corresponding Hough groove, then inserting the second connecting end of the second induction coil into the corresponding Hough groove, then inserting the third connecting end of the third induction coil into the corresponding Hough groove, and then inserting the fourth connecting end of the fourth induction coil into the corresponding Hough groove.

[0009] In the second step, inserting the first connection end of the first induction coil into the corresponding Hough slot is inserting the first connection end of the first induction coil into the corresponding Hough slot, and at this time, the first induction end of the first induction coil is located on one side of the plate insulating sheet; Inserting the second connection end of the second induction coil into the corresponding Hough groove is inserting the second connection end of the second induction coil into the corresponding Hough groove, at this time, the bottom of the second induction end of the second induction coil is higher than the top of the first induction end; Inserting the third connection end of the third induction coil into the corresponding Hough slot is inserting the third connection end of the third induction coil into the corresponding Hough slot, at which time, the third induction end of the third induction coil is symmetrical with the first induction end along the center line of the plate insulation sheet; Inserting the fourth connection end of the fourth induction coil into the corresponding Hough slot means inserting the fourth connection end of the fourth induction coil into the corresponding Hough slot. At this time, the fourth induction end of the fourth induction coil is symmetrical with the second induction end along the center line of the plate insulation sheet.

[0010] In the second step, the first connecting end of the first induction coil is inserted into the corresponding Hough slot by inserting the first vertical end of the first connecting end into the corresponding Hough slot, and at this time, the first horizontal end located at the top of the first vertical end makes the first induction end located on one side of the plate insulating sheet; The inserting of the second connecting end of the second induction coil into the corresponding Hough groove is to insert the second vertical end of the second connecting end into the corresponding Hough groove, and at this time, the second horizontal end located at the top of the second vertical end makes the bottom of the second induction end higher than the top of the first induction end; The inserting of the third connecting end of the third induction coil into the corresponding Hough slot is to insert the third vertical end of the third connecting end into the corresponding Hough slot, and at this time, the third horizontal end located at the top of the third vertical end makes the third induction end symmetrical with the first induction end along the center line of the plate insulation sheet; Inserting the first connecting end of the fourth induction coil into the corresponding Hough groove is inserting the fourth vertical end of the fourth connecting end into the corresponding Hough groove. At this time, the fourth horizontal end located at the top of the fourth vertical end makes the fourth induction end symmetrical with the second induction end along the center line of the board insulation sheet.

[0011] In the second step, the connecting plate vertically connected to the busbar and the sensing device are connected by first connecting the connecting plate vertically connected to the busbar and the sensing device, and then connecting the water inlet pipe on one side of the connecting end to the water pipe; In the third step, the sensing end is moved back and forth along the axis direction of the shaft part, and at the same time, the water in the water pipe passes through the connecting cavity in the connecting end in sequence, and then the water flows into the sensing cavity in the sensing end, and then the water flows to the inclined surface of the sensing end, and then the water flows out from the water spray holes on the inclined surface.

[0012] In the third step, the water flow is sprayed out from the water spray holes on the inclined surface, that is, the water flow is sprayed out from the top water spray holes on the inclined surface, and the water flow is sprayed out from the bottom water spray holes on the inclined surface.

[0013] In the third step, the water flow sprayed from the top water spray hole on the slope is the water flow sprayed from the top water spray hole on the slope along forty-five degrees, and the water flow sprayed from the bottom water spray hole on the slope is the water flow sprayed from the bottom water spray hole on the slope along forty-five degrees.

[0014] The connecting the water inlet pipe with the water pipe is to connect the pipe joint on the water inlet pipe with the water pipe.

[0015] In the second step, aligning the Huff holes of the Huff clamp with the confluence holes on the confluence plate, and then inserting the fixing screws into the Huff holes and the confluence holes in sequence is to align the four Huff holes on the Huff clamp with the four confluence holes on the confluence plate, and then inserting the fixing screws into the Huff holes and the confluence holes in sequence.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In an induction method suitable for simultaneous quenching of multiple shaft parts of the present invention, the method comprises the following steps: the first step: first counting the number and diameter of the shaft parts to be processed, and then selecting a suitable induction coil; the second step: first inserting the induction coil into the half clamp, and then fixing the insulating sheet between adjacent induction coils, and then fixing the half clamp to the busbar, at this time, the half groove clamps all the induction coils to fix the induction coils, and then connecting the connecting plate vertically connected to the busbar to the induction device; the third step: first inserting all the shaft parts into the corresponding induction coils, so that there is a certain gap between the shaft parts and the induction coils, and then allowing the induction device to pass current to the induction coil, and then the current generates an induction current on the surface of the shaft parts, and the induction current generates heat on the outer surface of the shaft parts to complete the heating stage in induction quenching. The advantages of the present invention also include: First point: Use the Hough clamp to connect multiple induction coils at the same time. The material of each induction coil is the same, so its resistance is roughly the same. Then each induction coil has a current of roughly the same size. The current then generates an induced current on the surface of the shaft parts, and then the thermal effect of the induced current completes the heating stage of induction quenching. Therefore, this method can perform induction quenching on multiple shaft parts at the same time, and the quenching efficiency is high. Second point: There is a certain gap between the induction coil and the shaft parts to prevent the induction coil from connecting with the shaft parts and causing the current to break through the shaft parts, thereby causing damage to the shaft parts; each induction coil is insulated with an insulating sheet to prevent short circuit accidents between the induction coils, and the two busbars are insulated with a plate insulating sheet to prevent short circuit accidents between the busbars; therefore, this method is relatively safe; Third point: The induction coil and the half clamp are detachably connected, that is, induction coils of different sizes can be replaced according to the diameter of the shaft parts. Therefore, the adaptability of this method is relatively wide. When the difference in the diameters of the induction ends is not significant, the resistance of the induction ends is approximately the same, that is, the magnitude of the current is approximately the same, and the effect of induction hardening on all shaft parts is the same; when the induction coil is damaged, the induction coil can be replaced; after the induction hardening is completed, the induction coil, the half clamp and the busbar can also be removed and stored, saving storage space; Therefore, the present invention can perform induction hardening on multiple shaft parts simultaneously and has relatively high safety.

[0017] 2. In the induction method for simultaneously quenching multiple shaft parts of the present invention, in the second step, the induction coil includes a first induction coil, a second induction coil, a third induction coil and a fourth induction coil. The first induction coil, the second induction coil, the third induction coil and the fourth induction coil are symmetrically distributed along the plate insulation sheet. During application, the first induction coil, the second induction coil, the third induction coil and the fourth induction coil are arranged in a "field" shape, so that induction heating can be performed on four shaft parts simultaneously. The positions of the induction coils do not overlap, so the induction coils will not interfere with each other; and the "field" shape arrangement can save the space occupied during induction hardening, so the limitation on the production site is small. Therefore, the present invention occupies less space.

[0018] 3. In the induction method for simultaneously quenching multiple shaft parts of the present invention, in the third step, while the induction end moves back and forth along the axis direction of the shaft part, the water spray holes on the induction coil spray water flow at an angle of 45 degrees. During application, the water flow sprayed out from the water spray holes falls onto the outer surface of the shaft part to cool the outer surface of the shaft part, thereby completing the cooling stage in the induction hardening; there is no need to put the shaft part that has passed through the heating stage into the cooling pool again, so the cooling efficiency is improved. Therefore, the present invention has high cooling efficiency.

[0019] 4. In the induction method for simultaneously quenching multiple shaft parts of the present invention, in the second step, the number of half holes is four, and the half holes are located on the half plates on both sides of the half groove. During application, when the fixing screws are sequentially inserted into the half holes and the busbar holes, the half plates clamp the half groove from both sides of the half groove, so the half groove clamps the induction coil to achieve a fixing effect. At the same time, the fixation between the half clamp and the busbar is realized. The four half holes make the clamping effect and connection effect of the half clamp stable. Therefore, the present invention has a stable connection effect. BRIEF DESCRIPTION OF THE DRAWINGS
