Description

Technical Field

[0001] This utility model relates to the field of spring processing technology, specifically a spring processing machine tool. Background Technology

[0002] Spring processing machine tools are core equipment specifically designed for manufacturing various types of springs, and are widely used in industries such as automotive, machinery, electronics, and home appliances. When processing compression springs, end face grinders are used to precisely grind both ends of the spring to ensure the flatness and perpendicularity of the end faces, meeting high-precision assembly requirements. However, the grinding process generates a large amount of metal shavings. If not handled promptly, this not only pollutes the working environment but may also affect the equipment's lifespan and the quality of the processed springs.

[0003] Currently, most spring processing machine tools are equipped with dust removal devices that use filter plates to adsorb and filter grinding waste. However, after long-term use, existing filter plates are prone to a significant decrease in filtration efficiency due to waste accumulation or pore blockage, requiring machine shutdown for filter plate replacement. Since the dust removal system is linked to the processing flow, replacement requires interrupting the entire dust removal process, directly impacting continuous spring production and reducing processing efficiency. Especially in high-volume production scenarios, frequent downtime for maintenance leads to lost production capacity and increased production costs. Summary of the Invention

[0004] The purpose of this utility model is to provide a spring processing machine tool to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a spring processing machine tool, comprising a machine tool body, wherein an installation door is installed on the outer surface of the machine tool body, and a cleaning component and a replacement component are provided inside and on the surface of the machine tool body;

[0006] The replacement component includes:

[0007] The joystick is used to drive the synchronous movement of various components.

[0008] The rotating shaft is used to drive the circular plate to rotate.

[0009] Rubber columns are used to block and change the direction of waste materials.

[0010] Limiting element, used to prevent the joystick from rotating on its own.

[0011] Preferably, the cleaning assembly includes a dust suction hood fixed inside the machine tool body. A negative pressure fan is fixed to the back of the machine tool body. The input end of the negative pressure fan passes through the machine tool body and is interconnected with the dust suction hood. A three-way pipe is fixed to the output end of the negative pressure fan. A collection box is installed at the end of the three-way pipe away from the negative pressure fan. A sealing door is installed on the outer surface of the collection box. A filter screen is installed on the outer surface of the collection box. A partition is fixed to the inner wall of the collection box. A base plate is fixed to the inner wall and outer surface of the collection box and the partition. A filter plate is placed on the top of the base plate. When the negative pressure fan is turned on, grinding waste is sucked into the three-way pipe and guided into the collection box. After being filtered by the filter plate, the waste is retained in the box, while the exhaust gas is discharged through the filter screen, thus achieving the collection and cleaning of waste.

[0012] Preferably, the rocker arm is rotatably connected to the outer surface of the collection box, the output shaft of the rocker arm passes through the collection box, and the output shaft of the rocker arm is rotatably connected to the collection box. A rotating shaft is rotatably connected to the inner wall of the collection box. One end of the rotating shaft is fixedly connected to the output shaft of the rocker arm. A circular plate is fixed to the end of the rotating shaft away from the rocker arm. An abutting rod is fixed to the side of the circular plate away from the rotating shaft. A sliding rod is abutted to the outer surface of the abutting rod. A fixing plate is fixed to the top of the sliding rod. A rubber column is fixed to the top of the fixing plate. A stabilizing rod is fixed to the top of the fixing plate. A fixing frame is fixed to the top of the inner wall of the collection box. The outer surface of the stabilizing rod is slidably connected to the inner side of the fixing frame. Rotating the rocker arm causes the rotating shaft, the circular plate, and the abutting rod to rotate synchronously, pushing the sliding rod, the fixing plate, and the rubber column upward, so that the rubber column accurately blocks one outlet of the three-way pipe, thereby changing the direction of waste entering.

[0013] Preferably, the limiting component includes a connecting block, which is disposed on the outer surface of the rocker arm. A screw is fixed on the outer surface of the connecting block. The end of the screw away from the connecting block passes through the rocker arm and is threadedly connected to the rocker arm. The screw abuts against the outer surface of the collection box, which can limit the rocker arm and prevent the rocker arm's rotation from affecting the sealing of the rubber column to the outlet of the three-way pipe.

[0014] Preferably, a three-jaw chuck is installed on the left side of the inner wall of the machine tool body, and a cylinder is fixed on the right side of the machine tool body. The output end of the cylinder passes through the machine tool body, and a motor is fixed to the output end of the cylinder. A grinding disc is fixed on the surface of the output shaft of the motor. The spring is placed in the three-jaw chuck for fixation. At this time, the motor is turned on and the cylinder is turned on at the same time, so that the grinding disc moves close to the spring to perform grinding.

[0015] Preferably, two sets of the sealing door, bottom plate, filter plate, and filter screen are provided, and the two sets of sealing doors, bottom plates, filter plates, and filter screens are symmetrically arranged with the center line of the collection box as the axis of symmetry, which facilitates replacement.

[0016] Preferably, the replacement components are provided in two sets, and both sets of replacement components are symmetrically arranged with the center line of the collection box as the axis of symmetry, which can alternately block the outlet of the three-way pipe, facilitating the subsequent replacement of the filter plate.

[0017] Compared with the prior art, the present invention provides a spring processing machine tool, which has the following beneficial effects:

[0018] 1. This spring processing machine tool, through its replaceable components, operates by first rotating a set of connecting blocks to disengage the screw from the collection box. At this point, the rocker arm can rotate freely, causing the rotating shaft, circular plate, and contact rod to rotate synchronously. This pushes the sliding rod, fixing plate, and rubber column upwards, precisely blocking one outlet of the tee pipe under the guidance of the stabilizing rod and fixing frame. After completion, the connecting blocks are rotated in the opposite direction to re-clamp the screw against the collection box, locking the rocker arm position. Simultaneously, another set of rocker arms operates in the reverse direction, causing the corresponding rubber column to switch the waste flow to another filter plate. The sealing door can then be opened to replace the filter plate. The entire process requires no machine downtime, significantly improving processing efficiency.

[0019] 2. This spring processing machine tool, through its cleaning components, activates a negative pressure fan when grinding springs. Grinding waste is sucked into a three-way pipe and guided into a collection box. After being filtered by a filter plate, the waste remains in the box, while the exhaust gas is discharged through a filter screen, thus achieving the collection and cleaning of waste and preventing it from affecting the grinding operation.

[0026] like Figure 1-5 As shown, this utility model provides a technical solution: a spring processing machine tool, including a machine tool body 1, an installation door 2 installed on the outer surface of the machine tool body 1, and a cleaning component 6 and a replacement component 7 provided inside and on the surface of the machine tool body 1; the replacement component 7 includes: a rocker arm 70, a rotating shaft 71, a circular plate 72, a contact rod 73, a slide rod 74, a fixing plate 75, a rubber column 76, a stabilizing rod 77, a fixing frame 78, a limiting component 79, a connecting block 790, and a screw 791.

[0027] A rocker arm 70 is rotatably connected to the outer surface of a collection box 63. The output shaft of the rocker arm 70 passes through the collection box 63 and is rotatably connected to the collection box 63. A rotating shaft 71 is rotatably connected to the inner wall of the collection box 63. One end of the rotating shaft 71 is fixedly connected to the output shaft of the rocker arm 70. A circular plate 72 is fixed to the end of the rotating shaft 71 away from the rocker arm 70. An abutment rod 73 is fixed to the side of the circular plate 72 away from the rotating shaft 71. A sliding rod 74 abuts against the outer surface of the abutment rod 73. A fixing plate 75 is fixed to the top of the sliding rod 74. A rubber column 76 is fixed to the top of the fixing plate 75. A stabilizing rod 77 is fixed to the top of the fixing plate 75. A fixing frame 78 is fixed to the top of the inner wall of the collection box 63. The outer surface of the stabilizing rod 77... The surface is slidably connected to the inner side of the fixed frame 78. The limiting member 79 includes a connecting block 790, which is set on the outer surface of the rocker arm 70. A screw 791 is fixed on the outer surface of the connecting block 790. The end of the screw 791 away from the connecting block 790 passes through the rocker arm 70, and the screw 791 is threadedly connected to the rocker arm 70. Two sets of replacement components 7 are provided, and both sets of replacement components 7 are symmetrically arranged about the center line of the collection box 63. During operation, first rotate one set of connecting blocks 790 to disengage the screw 791 from the collection box 63. At this time, the rocker arm 70 can rotate freely, driving the rotating shaft 71, the circular plate 72, and the abutment rod 73 to rotate synchronously, thereby pushing the slide rod 74, the fixed plate 75, and the rubber column 76 to move upward. The stabilizing rod 77 and the fixed frame 78 ensure smooth movement, allowing the rubber column 76 to accurately block one outlet of the three-way pipe 62. After completion, rotate the connecting block 790 in the opposite direction to make the screw 791 re-press against the collection box 63, locking the position of the rocker arm 70 to prevent loosening. The other set of rockers 70 operates in the opposite direction, causing the corresponding rubber column 76 to switch the flow of waste chips to another filter plate 68. At this time, the sealing door 64 can be opened to replace the filter plate 68. The entire process does not require stopping the machine, which significantly improves processing efficiency.

[0028] The cleaning component 6 includes a dust suction hood 60, which is fixed inside the machine tool body 1. A negative pressure fan 61 is fixed to the back of the machine tool body 1. The input end of the negative pressure fan 61 passes through the machine tool body 1 and is interconnected with the dust suction hood 60. A three-way pipe 62 is fixed to the output end of the negative pressure fan 61. A collection box 63 is installed at the end of the three-way pipe 62 away from the negative pressure fan 61. A sealing door 64 is installed on the outer surface of the collection box 63. A filter screen 65 is installed on the outer surface of the collection box 63. A partition 66 is fixed to the inner wall of the collection box 63. The inner wall of the collection box 63 and the partition 66 are connected. A base plate 67 is fixed to both the wall and the outer surface. A filter plate 68 is placed on top of the base plate 67. Two sets of sealing doors 64, base plates 67, filter plates 68, and filter screens 65 are provided. The two sets of sealing doors 64, base plates 67, filter plates 68, and filter screens 65 are symmetrically arranged with the center line of the collection box 63 as the axis of symmetry. After the negative pressure fan 61 is turned on, grinding waste will be sucked into the three-way pipe 62 and introduced into the collection box 63. After being filtered by the filter plate 68, the waste will be retained in the box, while the exhaust gas will be discharged through the filter screen 65, thus realizing the collection and cleaning of waste. When replacing, the corresponding sealing door 64 can be opened and the filter plate 68 can be pulled out for replacement.

[0029] A three-jaw chuck 5 is installed on the left side of the inner wall of the machine tool body 1, and a cylinder 3 is fixed on the right side of the machine tool body 1. The output end of the cylinder 3 passes through the machine tool body 1, and a motor 4 is fixed on the output end of the cylinder 3. A grinding disc is fixed on the surface of the output shaft of the motor 4. The spring is placed in the three-jaw chuck 5 and fixed. At this time, the motor 4 is turned on and the cylinder 3 is turned on at the same time, so that the grinding disc moves close to the spring to perform grinding.

[0030] When the spring needs to be processed, rotate one of the connecting blocks 790 to disengage the screw 791 from the collection box 63. The rocker arm 70 can then be rotated normally. The rocker arm 70 drives the rotating shaft 71 to rotate, which in turn drives the circular plate 72 and the contact rod 73 to rotate synchronously. At this time, the sliding rod 74, the fixing plate 75, and the rubber column 76 move upwards. Simultaneously, the movement of the sliding rod 74 and the fixing plate 75 is stabilized by the stabilizing rod 77 and the fixing frame 78, causing the rubber column 76 to block one outlet of the three-way pipe 62. Then, rotate the connecting block 790 again to make the screw 791 contact the outer surface of the collection box 63, thus limiting the rocker arm 70 and preventing it from rotating and affecting the seal of the rubber column 76 on the three-way pipe 62. The spring is then placed in the three-jaw clamp. The grinding disc is fixed inside the disc 5. At this time, the motor 4 is turned on, and the cylinder 3 is turned on at the same time. This allows the grinding disc to move close to the spring for grinding. At the same time, the negative pressure fan 61 is turned on, so that the waste generated by grinding enters the collection box 63 through one of the outlets of the three-way pipe 62. It is filtered by the filter plate 68, and the waste remains in the collection box 63. The exhaust gas is discharged through the filter screen 65. When the filter plate 68 needs to be replaced, the two sets of rocker arms 70 are rotated in opposite directions. Repeating the above steps will change the direction of the waste entering the rubber column 76, so that another set of filter plates 68 can perform the filtering work. At this time, the corresponding sealing door 64 can be opened to pull out the filter plate 68 for replacement without stopping the equipment operation, thus improving its processing efficiency.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
