Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of induction quenching, in particular to a sliding block induction quenching device. BACKGROUND

[0002] Linear guide rail is used to support and guide the moving parts to move in a given direction, which can be generally divided into: roller linear guide rail, cylindrical linear guide rail and ball linear guide rail. Linear guide rail is used for linear reciprocating motion and has higher rated load than linear bearing, and can bear certain torque, so that high-precision linear motion can be realized under high load.

[0003] Linear guide rail is composed of a sliding block and a guide rail. The guide rail is a fixed element, and the sliding block is a moving element that moves linearly along the guide rail. In general, the sliding block and the guide rail are connected by rolling steel balls. The inner wall of the sliding block is provided with a rolling groove for installing the steel balls. The steel balls are infinitely rolled and circulated between the rolling grooves and the guide rail, so that the load platform can easily move linearly along the guide rail with high precision, and the friction coefficient is reduced to one-fiftieth of the traditional sliding guide, and high positioning accuracy can be easily achieved.

[0004] During the process of infinite rolling and circulation of the steel balls between the rolling grooves, the steel balls need to bear loads in all directions, so the inner wall of the rolling groove needs to have high load resistance. Therefore, the strength of the inner wall of the rolling groove of the sliding block needs to be improved during the processing link.

[0005] A linear guide rail sliding block processing technology is disclosed in the patent with publication number CN106826111A. In the heat treatment process of the sliding block, the entire outer surface of the sliding block is first subjected to carburizing treatment, then quenching treatment, and finally low-temperature tempering. Although this method can improve the strength of the inner wall of the rolling groove of the sliding block, the carburizing and quenching treatment of the entire outer surface of the sliding block has a long production cycle and high energy consumption. In addition, the high quenching temperature and long time result in large quenching deformation of the sliding block, which is difficult to control, and the subsequent grinding process will thin the surface layer with the highest strength and maximum compressive stress, resulting in a decrease in the strength of the part and an increase in the processing difficulty and time.

DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0045] As shown in the drawings, Figure 1 in conjunction with Figures 2-3 the embodiments of the present application disclose a sliding block induction quenching equipment, which comprises a rack 1, a feeding conveying line 2, a clamping tool 3, a transfer mechanism 4 and an induction quenching mechanism 5.

[0046] The rack 1 is used to provide an operation space for the induction quenching of the sliding block S, and is also used to provide a mounting base for the clamping tool 3, the transfer mechanism 4 and the induction quenching mechanism 5.

[0047] The feeding conveying line 2 is used to convey the sliding block to the inside of the rack 1. The feeding conveying line 2 is arranged on one side of the rack 1 and has a feeding end and a discharging end arranged oppositely, so as to convey the sliding block from the feeding end to the discharging end. The discharging end extends to the inside of the rack 1, and the sliding block can be manually or mechanically fed at the feeding end and conveyed on the feeding conveying line 2 to the discharging end to wait for the next quenching operation.

[0048] The clamping tool 3 is fixedly arranged on the rack 1 and located on the side of the feeding conveying line 2 close to the discharging end, and is used to vertically clamp and fix the sliding block, so as to facilitate the induction quenching mechanism 5 to perform the quenching operation on the sliding block on the clamping tool 3.

[0049] The transfer mechanism 4 is arranged on the rack 1 and used to transfer the sliders on the feeding end to the clamping tool 3 in sequence.

[0050] The induction quenching mechanism 5 comprises a lifting device 51 and an inductor 52. The inductor 52 is arranged on the front side of the clamping tool 3, and the lifting device 51 is arranged on the rack 1 and used to drive the inductor 52 to move up and down to enter the slider and quench the inner wall of the rolling groove of the slider.

[0051] According to the above technical scheme, the sliders on the feeding conveying line 2 are transferred to the clamping tool 3 in sequence by the transfer mechanism 4, the clamping tool 3 clamps and fixes the vertically placed sliders, the inductor 52 is driven by the lifting device 51 to enter the slider and quench the inner wall of the rolling groove of the slider in the vertical direction. Compared with the traditional quenching method, the whole quenching process has a short process cycle, is energy-saving and environmentally friendly, and the inductor 52 only quenches the position of the inner wall of the slider that needs to be quenched, so that the strength of the inner wall of the quenched slider can be ensured while avoiding large deformation caused by quenching.

[0052] In order to clamp and fix the vertically placed sliders, referring to FIGS. 1-2, Figure 4 and 5 It is shown that the clamping tool 3 has a preferred embodiment, specifically, the clamping tool 3 comprises a mounting seat 31, a first clamping piece 32, a second clamping piece 33, a first telescopic element 34 and a second telescopic element 35.

[0053] The mounting seat 31 has a mounting cavity 311 with a top opening. A passage 312 extending through the mounting seat 31 is arranged at the center of the side of the mounting seat 31 close to the inductor 52. The inductor 52 is located on the side of the mounting seat 31 close to the passage 312. In this embodiment, the inductor 52 corresponds to the passage 312 in the vertical direction, so that the inductor 52 can conveniently enter and exit the passage 312 in the vertical direction.

[0054] A through hole 313 communicating with the passage 312 is arranged at the center of the inner bottom surface of the mounting cavity 311. The through hole 313 corresponds to the sliding groove on the vertically placed slider on the inner bottom surface of the mounting cavity 311. The passage 312 and the through hole 313 are used for the inductor 52 to enter and exit.

[0055] In this embodiment, the slider is vertically placed in the mounting cavity 311, and the sliding groove of the slider faces the side of the passage 312, and the sliding groove of the slider corresponds to the through hole 313 in the vertical direction. In this way, the inductor 52 can enter the sliding groove of the slider through the passage 312 and the through hole 313, so as to realize the vertical translation of the inductor 52 in the sliding groove of the slider, and then complete the induction quenching of the inner walls of the rolling grooves on both sides of the slider.

[0056] Because the sliding groove space of the sliding block is small, and the inductor 52 is large in size, the inductor 52 has not only the effective ring 523 for inductively hardening the inner wall of the rolling groove, but also the water spraying box 528 for hardening and cooling the sliding block, and the components of the conductive row, which are integrated on the inductor 52, so that the inductor 52 as a whole cannot be completely inserted into the sliding groove of the sliding block to realize the hardening operation.

[0057] Therefore, the application sets the passage 312 and the through hole 313 on the mounting seat 31, on the one hand, the inductor 52 only has part of the structure in the vertical direction opposite to the passage 312 and the through hole 313, and the other structure is outside the mounting seat 31, so that the structure component of the inductor 52 capable of directly realizing inductive hardening can enter the sliding groove, thereby realizing the compact cooperation of the inductor 52 through the mounting seat 31 to realize the inductive hardening operation on the small space of the sliding block.

[0058] At the same time, because the sliding groove of the sliding block is towards the passage 312 side, the sliding groove side of the sliding block is attached to the inner wall of the mounting cavity 311, so that the one-side positioning through the inner wall of the mounting cavity 311 can be realized.

[0059] In order to complete the clamping and positioning of the other three surfaces of the sliding block, the first clamping piece 32 is arranged on the side of the through hole 313 away from the passage 312, and the first telescopic element 34 is fixedly arranged on the side of the mounting seat 31 away from the inductor 52, for driving the first clamping piece 32 to translate towards the inductor 52.

[0060] The second clamping piece 33 is provided with two and symmetrically arranged on the left and right sides of the through hole 313, and the mounting seat 31 is provided with the first telescopic element 34 on the left and right sides, respectively, and the second telescopic element 35 is used for driving the second clamping piece 33 to translate towards the middle of the mounting cavity 311.

[0061] Therefore, by means of the inner wall of the corresponding mounting cavity 311 of the passage 312 and the three clamping pieces, the sliding block can be firmly fixed above the through hole 313 in the horizontal direction, while meeting the inductor 52 entering the inside of the sliding block on the side of the mounting seat 31 close to the passage 312, the reliable clamping and fixing of the sliding block are realized. The cooperation structure of the whole clamping tool 3 and the inductor 52 is compact, which can avoid occupying a large space in the horizontal and vertical directions of the inductor 52 and the clamping tool 3.

[0062] In the above embodiment, the first telescopic element 34 and the second telescopic element 35 are gas cylinders or oil cylinders.

[0063] In order to realize the hardening of the inner walls of the rolling grooves on both sides of the sliding block, the application shows a preferred embodiment of the inductor 52. Specifically, referring to the accompanying drawings, Figures 6-7As shown, the inductor 52 comprises a positive electrode conductive row 521, a negative electrode conductive row 522 and two symmetrical effective rings 523, the two effective rings 523 are vertically spaced and correspond to the through hole 313 in the vertical direction.

[0064] The same end of the two effective rings 523 is fixedly connected with the positive electrode conductive row 521 and the negative electrode conductive row 522 respectively, and the end of the positive electrode conductive row 521 and the negative electrode conductive row 522 away from the effective ring 523 is used for connecting with the quenching transformer, and the other end of the two effective rings 523 is connected with each other, and the effective ring 523 is provided with an induction part 5231 matched with the inner wall of the rolling groove of the slider.

[0065] Therefore, the two effective rings 523 are vertically spaced, and the induction part 5231 on the surface of the two effective rings 523 is matched with the inner wall of the rolling groove, and the two effective rings 523 are connected in series, and the current at each position of the effective ring 523 is consistent, so that the rolling groove quenching parameters and performance consistency of the two sides of the slider inside can be realized, and the strength of the inner wall of the rolling groove of the two sides of the slider after quenching is uniform.

[0066] In the above embodiment, the outer shape of the induction part 5231 is matched with the contour of the inner wall of the rolling groove, and it is worth noting that the center longitudinal section of the two effective rings 523 is located at the center of the through hole 313, so that the distance between the induction part 5231 on the two effective rings 523 and the inner wall of the rolling groove of the two sides of the slider is equal, so that the inductor 52 can realize one-time induction quenching of the inner wall of the rolling groove of the two sides of the slider during the up-down translation, and can ensure that the structural strength after quenching meets the design requirements, and more importantly, can ensure that the quenching layer of the inner wall of the rolling groove of the two sides of the slider is uniform, and by effectively controlling the electrical parameters of the two effective rings 523 and the up-down translation speed, the deformation amount of the inner wall of the slider during quenching can be effectively controlled, the deformation is minimized, and the deformation amounts of the two sides are consistent. In the subsequent inner wall grinding process, the same grinding parameters can be used to quickly correct the size of the inner wall of the slider.

[0067] The embodiment shows a preferred structure of the effective ring 523, specifically, the effective ring 523 comprises a vertical section 5232 and a horizontal section 5233, the two vertical sections 5232 are spaced and parallel, the horizontal section 5233 is fixedly connected with the bottom end of the two vertical sections 5232, the induction part 5231 is arranged on the side wall of the vertical section 5232, the top end of one of the two vertical sections 5232 away from the clamping tool 3 is used for fixedly connecting with the positive electrode conductive row 521 or the negative electrode conductive row 522, and the top end of the vertical section 5232 of the two effective rings 523 close to the clamping tool 3 is connected with each other.

[0068] By means of the above technical scheme, the induction portion 5231 can be arranged on the outer wall of the vertical segment 5232, so that the whole effective ring 523 is simple in structure, and the inner wall of the rolling groove can be precisely quenched by the corresponding induction portion 5231 of the vertical segment 5232. In the embodiment, the induction portion 5231 and the vertical segment 5232 are integrally formed.

[0069] As some preferred embodiments, the fixing member 524 is further arranged between the two effective rings 523, the fixing member 524 is provided with the magnetic conductor 5241 connected with the vertical segment 5232, and the bottom end of the fixing member 524 is fixedly connected with the horizontal segment 5233. By means of the magnetic conductor 5241, the induction efficiency of the effective ring 523 can be improved.

[0070] In order to cool the effective ring 523, the inductor 52 further comprises the water outlet pipe 525, the hollow inside the positive electrode conductive row 521, the negative electrode conductive row 522 and the effective ring 523, the water outlet pipe 525 is arranged in parallel above the positive electrode conductive row 521 and the negative electrode conductive row 522, the water outlet pipe 525 is provided with the insulating member 526 arranged on the positive electrode conductive row 521 and the negative electrode conductive row 522, one end of the water outlet pipe 525 is connected in parallel with the end of the two effective rings 523 close to the clamping tool 3, the other end of the water outlet pipe 525 is provided with the water outlet interface P, and the ends of the positive electrode conductive row 521 and the negative electrode conductive row 522 away from the effective ring 523 are respectively provided with the first water inlet interface S1.

[0071] By means of the above arrangement, the cooling water can be respectively introduced into the positive electrode conductive row 521 and the negative electrode conductive row 522 through the two first water inlet interfaces S1, the cooling water respectively enters the inside of the two effective rings 523, the two effective rings 523 are synchronously cooled, the cooled water is discharged through the water outlet interface P of the water outlet pipe 525, and the water is sequentially circulated. The above structure can ensure that the cooling performance of the two effective rings 523 is consistent, and further ensure that the induction quenching of the inner walls of the rolling grooves on both sides of the slider is uniform and consistent.

[0072] In addition, the water outlet pipe 525 is arranged on the positive electrode conductive row 521 and the negative electrode conductive row 522, so that a large volume of the surface of the effective ring 523 is not occupied, the structure of the whole inductor 52 is compact, and it is ensured that only the effective ring 523 moves up and down in the sliding groove of the slider, the positive electrode conductive row 521, the negative electrode conductive row 522 and the water outlet pipe 525 part move up and down in the channel 312, the whole inductor 52 and the mounting seat 31 are compactly matched, and the occupied space of the inductor 52 in the vertical direction is reduced.

[0074] In order to facilitate the feeding of the sliding block by the feeding conveying line 2, referring to FIG. 2, Figure 8 As shown in FIG. 2, the feeding conveying line 2 of the embodiment comprises a conveying frame 21 and a conveying belt 22 arranged on the conveying frame 21.
