Description

Technical Field

[0001] This invention relates to the field of feeder technology for Swiss-type lathes, and more specifically to a side feeder receiving device for Swiss-type lathes. Background Technology

[0002] Swiss-type lathes, as high-precision and high-efficiency machining equipment for small, complex parts, are widely used in the manufacturing of precision shaft parts in aerospace, medical devices, and electronic communications fields. During the machining process of a Swiss-type lathe, the bar stock is clamped by the spindle and then cut by a rear-mounted power tool or sub-spindle. The machined workpiece needs to be collected and transported through a receiving device.

[0003] Currently, the most commonly used receiving devices for Swiss-type lathes in the industry are box-type collection structures. These consist of a receiving box located below the machine tool's discharge port, where workpieces fall freely through guide channels for centralized collection. To prevent cutting fluid contamination of the working environment, some receiving boxes also have filter plates at the bottom for preliminary filtration and separation of cutting fluid adhering to the workpiece surface. However, existing box-type receiving devices have significant technical drawbacks in practical applications: because workpieces are stored in a stacked state within the receiving box, the workpieces that fall in first are covered and buried by those that fall in later. The undried cutting fluid on the surface of the later-processed workpieces continues to flow downwards under gravity, dripping directly onto the surface of the earlier-processed workpieces, causing secondary contamination of the collected workpieces. This phenomenon is particularly severe during continuous mass production, resulting in residual oil, iron filings, and other impurities on the workpiece surface. This not only affects the cleanliness and appearance of the workpieces but may also cause corrosion or oxidation of the workpiece surface due to the chemical components in the cutting fluid, thereby reducing the product yield. In addition, the disorderly stacking of workpieces in the box makes it inconvenient to retrieve materials. Operators need to manually search for or pick out the stacked workpieces one by one, which increases labor intensity and working time, making it difficult to meet the requirements of modern automated production lines for efficient, clean and orderly material discharge.

[0004] Therefore, a side discharge receiving device is needed to achieve workpiece separation and conveying, immediate removal of cutting fluid, and orderly collection of workpieces, in order to solve the problem of secondary pollution caused by workpiece accumulation in the existing receiving box, and to improve the automation level and workpiece cleanliness of the Swiss-type lathe discharge process. Summary of the Invention

[0005] To address the problems existing in the prior art, a side-discharge receiving device for a Swiss-type turning machine is provided. This device consists of two parallel conveyor belts arranged in the receiving box, with receiving rods equipped with receiving grooves spaced evenly along the circumferential direction on the conveyor belts. Workpieces are individually supported in the receiving grooves after sliding off the feed plate, maintaining a distance between adjacent workpieces in the conveying direction. A drain outlet is provided through the bottom wall of the receiving groove, and a liquid collection hopper with an open top is installed between the two conveyor belts. As the workpiece moves downstream with the receiving rods, the cutting fluid adhering to the workpiece surface drips directly into the liquid collection hopper through the drain outlet and flows into the liquid collection tank. This achieves simultaneous workpiece conveying and cutting fluid removal, solving the problems of cutting fluid accumulation in the receiving box and residue on the workpiece surface.

[0006] To address the problems of existing technologies, this invention provides a side-discharge receiving device for a Swiss-type turning lathe, comprising: a receiving box disposed on one side of the Swiss-type lathe, with a feed inlet on the side facing the lathe, the feed inlet being connected to the discharge port of the lathe; the bottom wall of the inner cavity of the receiving box being recessed to form a liquid collection groove; and a pull-out opening on the side wall of the receiving box away from the lathe; two conveyor belts, horizontally spaced within the receiving box; and material-bearing rods equally spaced along the circumference of the two conveyor belts; a material-bearing groove extending along the length of the material-bearing rod, with a drain outlet penetrating through the bottom of the groove; and conveying... A drive mechanism is located on the outer wall of the receiving box, and its output end is connected to the conveyor belt to drive the conveyor belt to rotate cyclically around its axis. A liquid collection hopper is located in the receiving box between the two conveyor belts, with its top open and its bottom end connected to the liquid collection tank. A feed plate is inclinedly located in the receiving box and at the upstream end of the conveyor belt, with its bottom discharge side extending above the movement trajectory of the support rod to guide the workpiece into the support trough. A receiving box is slidably assembled at the pull-out opening, and has a receiving port on the side facing the conveyor belt. The receiving port is located below the downstream end of the conveyor belt to receive the workpiece falling from the support rod.

[0007] Preferably, the bottom wall of the material receiving trough is a V-shaped inclined structure that is low in the middle and high at both ends.

[0008] Preferably, an operation port is provided on the side wall of the receiving box, and an observation window is installed at the operation port, the observation window being arranged in a way that can be opened and closed.

[0009] Preferably, the conveying drive mechanism includes: a drive shaft and a driven shaft, which are arranged parallel to and rotatably in the receiving box; two drive pulleys, which are coaxially spaced on the drive shaft; two driven pulleys, which are coaxially spaced on the driven shaft; and two conveyor belts, which are respectively sleeved on the corresponding drive pulleys and driven pulleys; and a drive motor, which is located on the outside of the receiving box, and whose output shaft is connected to the drive shaft for transmission.

[0010] Preferably, the inner bottom surface of the liquid collecting hopper is constructed as a conical guide surface that converges from its periphery to the center. The bottom end of the liquid collecting hopper converges and is provided with a liquid discharge port, which is located above the liquid collecting tank and is connected to the liquid collecting tank.

[0011] Preferably, a return pipe is provided at the bottom of the receiving box, one end of which is connected to the bottom of the liquid collection tank, and the other end is connected to the cutting fluid pool of the Swiss-type lathe.

[0012] Preferably, a filter plate is fixedly provided at the bottom of the liquid collection tank, the filter plate divides the liquid collection tank into an upper liquid accumulation chamber and a lower reflux chamber, a filter hole is provided through the filter plate, and one end of the reflux pipe is connected to the bottom of the reflux chamber.

[0013] Preferably, the upper end of the feed plate is rotatably disposed in the receiving box, and the receiving box is further provided with a buffer adjustment assembly. The buffer adjustment assembly includes an adjustment frame and an elastic buffer element. The adjustment frame is disposed at the bottom of the feed plate in a direction perpendicular to the feed plate, and the elastic buffer element is sandwiched between the adjustment frame and the bottom end of the feed plate.

[0014] Preferably, the buffer adjustment assembly further includes: a guide rail disposed in the receiving box, wherein two sliders capable of sliding towards each other are provided; a bidirectional lead screw rotatably disposed in the guide rail, wherein each end of the lead screw has a threaded section with opposite directions of rotation, the two threaded sections being threadedly connected to the two sliders respectively, and one end of the bidirectional lead screw extending to the outside of the receiving box; and two connecting rods, one end of which is rotatably connected to the two sliders respectively, and the other end of which is rotatably connected to the adjustment frame.

[0015] The present invention also provides a sliding headstock turning machine, wherein a side discharge receiving device for the sliding headstock turning machine is provided at the discharge port.

[0016] The advantages of this invention compared to the prior art are: This invention achieves independent conveying and evenly spaced arrangement of workpieces by using the coordinated operation of dual conveyor belts and material-bearing rods. This effectively reduces the phenomenon of workpiece stacking and overlapping in traditional box-type material receiving, blocks the propagation path of cutting fluid from the post-processed workpiece to the surface of the pre-processed workpiece, solves the problem of secondary contamination of workpieces, and improves the surface cleanliness and rust prevention quality of finished workpieces.

[0017] The drain hole on the bottom wall of the receiving tank, together with the collection hopper and collection tank, forms a multi-stage cutting fluid recovery channel. During the workpiece transportation process, most of the cutting fluid can be drained and recovered. Compared with the passive filtration method of the single filter plate at the bottom of the traditional receiving box, this active draining structure not only drains more thoroughly and recovers more efficiently, but also avoids the accumulation and splashing of cutting fluid in the receiving box, effectively improving the cleanliness of the working environment.

[0018] The pull-out design of the receiving box, combined with the continuous operation of the conveyor belt, allows the workpiece collection process to be fully integrated into the automated rhythm of the equipment. Operators no longer need to rummage through or pick out workpieces in the receiving box, reducing labor intensity and operational risks. At the same time, the neat arrangement of workpieces in the receiving box also facilitates subsequent inspection, packaging, or transfer processes. Attached Figure Description

[0031] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 4As shown, a side-discharge receiving device for a Swiss-type turning lathe includes: a receiving box 1, which is disposed on one side of the Swiss-type turning lathe, and has a feed inlet 11 on the side facing the Swiss-type turning lathe. The feed inlet 11 is connected to the discharge port of the Swiss-type turning lathe. The bottom wall of the inner cavity of the receiving box 1 is recessed downward to form a liquid collection tank 12. A pull-out opening 13 is provided on the side wall of the receiving box 1 away from the Swiss-type turning lathe. Two conveyor belts 2 are arranged horizontally at intervals in the receiving box 1, and a bearing is arranged at equal intervals along the circumference between the two conveyor belts 2. The material receiving rod 21 has a material receiving groove 211 on the side opposite to the conveyor belt 2. The material receiving groove 211 extends along the length of the material receiving rod 21, and a drain outlet 212 is provided through the bottom of the groove. The conveying drive mechanism 3 is located on the outer wall of the receiving box 1, and its output end is connected to the conveyor belt 2 to drive the conveyor belt 2 to rotate cyclically around its axis. The liquid collecting hopper 4 is located in the receiving box 1 and between the two conveyor belts 2. Its top is open and its bottom is connected to the liquid collecting hopper. The trough 12 is connected to collect and guide the cutting fluid dripping from the workpiece; the feed plate 5 is inclinedly arranged in the receiving box 1 and located at the upstream end of the conveyor belt 2, with its bottom discharge side extending above the movement trajectory of the receiving rod 21 to guide the workpiece into the receiving trough 211; the receiving box 6 is slidably assembled at the pull-out port 13, and has a receiving port on the side facing the conveyor belt 2, which extends to the bottom of the downstream end of the conveyor belt 2 to receive the workpiece falling from the receiving rod 21; wherein After the workpiece is discharged from the outlet of the self-propelled machine, it enters the receiving box 1 through the feed port 11 and slides down the guide plate 5 into the receiving groove 211 of the receiving rod 21 at the upstream end of the conveyor belt 2. The operation of the conveyor belt 2 drives the receiving rod 21 and the workpiece to move downstream. The cutting fluid attached to the workpiece drips into the liquid collection hopper 4 through the drain port 212 and flows into the liquid collection groove 12. When the receiving rod 21 moves to the downstream end, it releases the workpiece. The workpiece falls into the receiving box 6 through the receiving port to complete the receiving.

[0033] The outside of the receiving box 1 is also equipped with file hooks 14.

[0034] An inclined seat 19 is provided at the bottom inner side of the feed inlet 11, and the guide plate 5 abuts against the bottom of the inclined seat 19. After the workpiece passes through the feed inlet 11, it is guided by the top of the inclined seat 19 and then falls into the guide plate 5.

[0035] The receiving box 1 is also provided with a limiting plate 8, which is inclined at the bottom of the upstream end of the conveyor belt 2 so as to form a discharge port facing the receiving trough 211 between the limiting plate 8 and the bottom end of the feeding plate 5.

[0036] The top of the receiving box 1 is provided with a material tray 18, which is used to place materials taken out of the box for static oil removal. The material tray 18 is provided with an oil drain hole, which can return the oil dripping from the product to the receiving box for recycling.

[0037] In practice, the workpiece processed by the Swiss-type lathe is discharged from the discharge port and enters the receiving box 1 through the feed port 11. The inclined seat 19 at the bottom of the inner side of the feed port 11 first guides the workpiece in the initial stage, so that the workpiece is smoothly transferred to the feed plate 5. The feed plate 5 is inclinedly set at the upstream end of the conveyor belt 2, and its bottom end abuts against the inclined seat 19. The workpiece slides down along the inclined surface of the feed plate 5 and, under the action of gravity, falls accurately into the receiving groove 211 of the upstream end receiving rod 21 through the drop port formed between the limiting plate 8 and the bottom end of the feed plate 5. The setting of the limiting plate 8 effectively prevents the workpiece from jumping or deviating at the moment of feeding.

[0038] Subsequently, the conveying drive mechanism 3 is started, and the double conveyor belts 2 operate synchronously, driving the material support rods 21 and the workpieces to move smoothly from the upstream end to the downstream end. Since the material support rods 21 are distributed at equal intervals along the circumference of the conveyor belt 2 and the adjacent material support troughs 211 are spaced apart from each other, the workpieces always maintain an independent support state during the conveying process, completely avoiding mutual stacking and contact between the workpieces.

[0039] During the transfer process, the cutting fluid adhering to the surface of the workpiece drips naturally under the action of gravity. It falls directly into the open opening of the collection hopper 4 below through the drain outlet 212 on the bottom wall of the receiving tank 211. The collection hopper 4 collects the cutting fluid and guides it to the collection tank 12 at the bottom of the receiving box 1, realizing the immediate recovery and centralized treatment of the cutting fluid.

[0040] When the receiving rod 21 moves to the downstream end of the conveyor belt 2, the receiving trough 211 gradually flips as the conveyor belt 2 turns. Under the action of gravity, the workpiece slides out of the receiving trough 211 and falls one by one into the receiving box 6, which is slidably assembled at the pull-out opening 13. The receiving box 6 neatly stores the workpieces. Operators can pull out the receiving box 6 at any time during equipment operation to transfer the workpieces without stopping the machine. In addition, the document hooks 14 set on the outside of the receiving box 1 are convenient for hanging production documents such as processing program sheets and inspection cards, and the material tray 18 set on the top of the receiving box 1 can be used to temporarily store the bar stock or finished workpieces to be processed, further optimizing the material management on the production site.

[0041] like Figure 6 As shown, the bottom wall of the material receiving groove 211 is a V-shaped inclined structure with a low middle and high ends. The material receiving groove 211 extends downward from the groove openings at both ends to the bottom of the groove in the middle, so as to automatically guide the workpiece to the middle position of the material receiving groove 211 when receiving the workpiece, and prevent the workpiece from deviating along the length direction of the material receiving rod 21.

[0042] When the workpiece slides from the feed plate 5 into the receiving groove 211, it first contacts the lowest point in the middle of the V-shaped groove bottom. Because the two side walls of the V-shape are symmetrically inclined, the workpiece, under the influence of its own weight, is subjected to a centripetal guiding force from the side walls. This guiding force continuously drives the workpiece to roll or slide towards the lowest point of the groove bottom until it is stably positioned in the middle of the receiving groove 211. Even if the workpiece deviates to one end of the groove due to a falling posture deviation or impact kinetic energy at the moment of feeding, the inclined guiding effect of the V-shaped groove walls will quickly correct it to the center position. This V-shaped self-centering structure ensures high repeatability of the workpiece's position within the receiving groove 211. Regardless of the initial posture of the workpiece as it falls into the groove, it will eventually be automatically guided to the axial center position of the receiving rod 21, effectively preventing the workpiece from shifting along the length of the receiving rod 21.

[0043] like Figure 2 As shown, an operation port is provided on the side wall of the receiving box 1, and an observation window 15 is installed at the operation port. The observation window 15 is set at the operation port in a manner that can be opened and closed.

[0044] The observation window 15 is normally kept closed. Its transparent material allows operators to monitor the material feeding at the upstream end of the conveyor belt 2, the workpiece support status on the support rod 21, and the dripping and collection of cutting fluid without interrupting equipment operation. If workpiece jamming, material deviation, or abnormal cutting fluid flow is detected, the operator can immediately make a judgment and take appropriate measures. When manual intervention is required for troubleshooting, foreign object removal, or manual adjustment of workpiece position, the operator can open the observation window 15 and directly reach into the receiving box 1 through the operating port to perform the operation. After the operation is completed, the observation window 15 can be closed to restore the sealed state. This combination of visibility and closable design ensures that the receiving device can balance convenience and safety in both daily operation and abnormal handling scenarios.

[0045] like Figure 4 As shown, the conveying drive mechanism 3 includes: a drive shaft 31 and a driven shaft 32, which are arranged parallel to and rotatably in the receiving box 1; two drive pulleys 33, which are coaxially spaced on the drive shaft 31; two driven pulleys 34, which are coaxially spaced on the driven shaft 32; and two conveyor belts 2, which are respectively sleeved on the corresponding drive pulleys 33 and driven pulleys 34; and a drive motor 35, which is located on the outside of the receiving box 1, and whose output shaft is connected to the drive shaft 31 for transmission.

[0046] After the drive motor 35 starts, its output torque is transmitted to the drive shaft 31. The drive shaft 31 simultaneously drives the two drive pulleys 33 on it to rotate synchronously. The two drive pulleys 33 drive their corresponding driven pulleys 34 to rotate around the driven shaft 32 through their respective conveyor belts 2. Since the two drive pulleys 33 are fixed to the same drive shaft 31, the rotational angular velocity of the two drive pulleys 33 remains highly consistent regardless of fluctuations in the speed of the drive motor 35 or changes in the load, thus ensuring strict synchronization of the linear speeds of the two conveyor belts 2. This coaxial integrated drive method ensures that the two conveyor belts 2 maintain the same pace of movement when carrying the support rod 21 and the workpiece, avoiding the risk of premature damage caused by the twisting and deformation of the support rod 21, workpiece skewing, or excessive force on one side of the conveyor belt 2 due to the asynchronous operation of the two belts.

[0047] like Figure 5 and Figure 9 As shown, the inner bottom surface of the liquid collecting hopper 4 is a conical guide surface that converges from its periphery to the center. The bottom end of the liquid collecting hopper 4 converges and is provided with a liquid discharge port. The liquid discharge port is located above the liquid collecting tank 12 and is connected to the liquid collecting tank 12.

[0048] During operation, as the workpiece is moved along with the receiving rod 21, the cutting fluid adhering to its surface drips through the drain outlet 212 on the bottom wall of the receiving tank 211. The cutting fluid droplets first fall onto the conical guide surface of the collecting hopper 4, and then, under the action of gravity, converge towards the center along the inclined direction of the guide surface, finally flowing into the collecting tank 12 below through the drain outlet at the bottom. The continuous inclined design of the conical guide surface prevents the cutting fluid from forming puddles on the guide surface, but keeps it flowing towards the center. Even if the equipment vibrates or the conveyor belt 2 starts and stops, causing droplets to splash, the cutting fluid can quickly flow back to the drain outlet, without remaining on the guide surface or flowing backward. This conical funnel-type guide structure ensures that the cutting fluid flows unidirectionally from dripping to collecting to discharge, effectively avoiding the accumulation and secondary splashing of cutting fluid in the collecting hopper 4.

[0049] like Figure 2 As shown, a return pipe 16 is provided at the bottom of the receiving box 1. One end of the return pipe 16 is connected to the bottom of the liquid collection tank 12, and the other end is connected to the cutting fluid pool of the Swiss Army CNC machine.

[0050] During operation, the cutting fluid collected in the collection tank 12 naturally settles at the bottom of the tank under gravity. When the liquid level gradually rises to the inlet height of the return pipe 16, the cutting fluid automatically flows through the return pipe 16 to the cutting fluid pool of the Swiss-type lathe. Continuous return of the cutting fluid can be achieved without any pumping power or manual intervention. Since the inlet of the return pipe 16 is located at the lowest point of the collection tank 12, the cutting fluid in the collection tank 12 can be almost completely drained, leaving only a very small amount of liquid film at the bottom of the tank, effectively preventing long-term accumulation and deterioration of the cutting fluid in the collection tank 12. This "low-level liquid intake and gravity return" design makes the cutting fluid recovery system of the receiving device and the original cutting fluid circulation system of the Swiss-type lathe organically integrated. The cutting fluid drained in the receiving box 1 is initially filtered by the filter plate 17 and then directly returned to the cutting fluid pool of the Swiss-type lathe through the return pipe 16 to participate in a new round of recycling, realizing the closed-loop circulation of cutting fluid in the entire process of processing, spraying, draining, recycling and reuse.

[0051] like Figure 4 As shown, a filter plate 17 is fixedly provided at the bottom of the liquid collection tank 12. The filter plate 17 divides the liquid collection tank 12 into an upper liquid accumulation chamber and a lower reflux chamber. A filter hole is provided through the filter plate 17. One end of the reflux pipe 16 is connected to the bottom of the reflux chamber to guide the clean cutting fluid filtered by the filter plate 17 to the cutting fluid pool of the Swiss-type lathe.

[0052] During operation, the cutting fluid discharged from the liquid collection hopper 4 first collects in the upper liquid accumulation chamber. As the liquid level gradually rises, the cutting fluid seeps downward through the filter holes on the filter plate 17 under the action of gravity. Solid impurities such as chips, burrs, and abrasive particles are intercepted and retained on the upper surface of the filter plate 17, while the clean cutting fluid after filtration and purification enters the lower return chamber. Since one end of the return pipe 16 is connected to the bottom of the return chamber, the clean cutting fluid in the return chamber continuously flows back to the cutting fluid pool of the Swiss-type lathe under the drive of gravity, completing the purification and recovery of the cutting fluid. This staged treatment method of "collecting first, filtering then returning" ensures that the cutting fluid entering the cutting fluid circulation system has completed primary solid-liquid separation before entering the pump body and nozzle, effectively reducing the content of solid impurities in the cutting fluid.

[0053] like Figure 5 , Figure 6 , Figure 8 and Figure 10As shown, the upper end of the feed plate 5 is rotatably disposed in the receiving box 1. The receiving box 1 is also provided with a buffer adjustment assembly, which includes an adjustment frame 71 and an elastic buffer element 72. The adjustment frame 71 is disposed at the bottom of the feed plate 5 in a direction perpendicular to the feed plate 5. The elastic buffer element 72 is sandwiched between the adjustment frame 71 and the bottom end of the feed plate 5. When the feed plate 5 receives the workpiece discharged from the self-propelled machine, the elastic deformation of the elastic buffer element 72 absorbs the impact energy of the falling workpiece, and the tilt angle of the feed plate 5 is changed by adjusting the vertical position of the adjustment frame 71.

[0054] During operation, the top of the feed plate 5 is always in contact with the bottom of the inclined seat 19. The operator can adjust the vertical height of the adjustment frame 71 to change the initial compression of the elastic buffer element 72, thereby precisely controlling its initial support pressure on the bottom of the feed plate 5.

[0055] When processing heavy steel or stainless steel parts, the operator adjusts the bracket 71 upwards to increase the initial compression of the elastic buffer element 72 and thus increase the initial pressure. The elastic buffer element 72 supports the bottom of the feed plate 5 with higher rigidity, so that it only undergoes slight elastic deformation when subjected to the impact load of heavy workpieces. The feed plate 5 can maintain a sufficiently large tilt angle to ensure that the heavy workpiece receives sufficient downward driving force and slides smoothly into the receiving groove 211. At the same time, the higher initial pressure gives the elastic buffer element 72 a larger compression margin and energy absorption potential, which can fully absorb the impact energy through further compression deformation at the moment of impact of the heavy workpiece, avoiding damage to the parts caused by rigid impact.

[0056] When processing small aluminum or copper alloy parts with low mass, the operator lowers the adjusting frame 71 to reduce the initial compression of the elastic buffer element 72, thereby reducing the initial pressure. The elastic buffer element 72 supports the bottom of the feed plate 5 with low stiffness. Under the load of the light workpiece, the feed plate 5 can sink moderately, and the tilt angle is reduced accordingly. The downward speed of the workpiece slows down, preventing the light and small parts from bouncing, deviating, or flying out when falling into the receiving groove 211 due to excessive downward speed. At the same time, the lower initial pressure allows the elastic buffer element 72 to provide a gentle cushioning feel when the light parts are fed, avoiding the light parts being rebounded or stuck due to excessively hard cushioning. By adjusting the initial compression of the elastic buffer element 72, the feeding characteristics of workpieces with different masses can be adapted.

[0057] like Figure 7 and Figure 10As shown, the buffer adjustment assembly further includes: a guide rail 73, disposed in the receiving box 1, wherein two sliders 74 capable of sliding in opposite directions are provided; a bidirectional lead screw 75, rotatably disposed in the guide rail 73, with threaded sections of opposite directions at both ends, the two threaded sections being threadedly connected to the two sliders 74 respectively, one end of the bidirectional lead screw 75 extending to the outside of the receiving box 1; and two connecting rods 76, one end of which is rotatably connected to the two sliders 74 respectively, and the other end of which is rotatably connected to the adjustment frame 71.

[0058] During operation, the operator rotates the end of the bidirectional lead screw 75 located outside the receiving box 1. The bidirectional lead screw 75 rotates around its axis. Due to the opposite directions of the threaded sections at both ends, the two sliders 74 slide synchronously towards or away from each other along the guide rail 73 under the drive of the threaded transmission. When the two sliders 74 move towards each other, the upper ends of the two connecting rods 76 synchronously retract inward, and the lower ends of the connecting rods 76 push the adjusting frame 71 upward together, causing the adjusting frame 71 to rise vertically. This increases the initial compression and initial pressure of the elastic buffer element 72, and consequently increases the support stiffness of the feed plate 5. When the two sliders 74 move away from each other, the upper ends of the two connecting rods 76 synchronously open outward, and the lower ends of the connecting rods 76 pull the adjusting frame 71 downward vertically. This decreases the initial compression and initial pressure of the elastic buffer element 72, and consequently reduces the support stiffness of the feed plate 5. like Figure 11 As shown, a sliding headstock turning machine is provided with a side discharge receiving device for the sliding headstock turning machine at its discharge port.

[0059] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
