Description

Technical Field

[0001] The utility model relates to the field of template processing, in particular to a template inversion clamping mechanism and transfer. Background Art

[0002] The Chinese patent with the announcement number CN209452868U discloses an inverted pick-up type special double-tool milling machine, which includes a bed, a slide, a saddle, a slide, a pick-up spindle, a rotary drive, a swing table, a loading conveyor belt and a unloading conveyor belt. The slide is mounted on the Z-axis linear guide rail of the bed and is driven by the Z-axis motor screw on the bed. The saddle is mounted on the Y-axis linear guide rail of the slide and is driven by the Y-axis motor screw on the slide. The slide is mounted on the X-axis linear guide rail of the saddle and is driven by the The X-axis motor screw drive is installed on the slide. The pick-up spindle adopts a high-speed torque electric spindle, and a hydraulic clamp is installed at the end. The hydraulic clamp is a hydraulic three-jaw chuck. The rotary drive is located on the front side of the slide on the bed. The rotary drive is provided with a built-in torque motor and a flange output shaft. The swing table is connected to the flange output shaft through a flange. The swing table is provided with a rough milling electric spindle and a fine milling electric spindle. The loading conveyor belt and the unloading conveyor belt are installed on the bed on the side of the swing table.

[0003] When the above structure processes the workpiece, the X-axis motor, Y-axis motor, and Z-axis motor must cooperate with each other to drive the hydraulic three-jaw chuck on the pickup spindle to clamp the workpiece on the loading conveyor belt. Then, the X-axis motor, Y-axis motor, and Z-axis motor are used to move the hydraulic three-jaw chuck holding the workpiece to the processing position. Finally, the workpiece is processed from bottom to top by the fine milling cutter and the rough milling cutter. However, the above structure uses a hydraulic three-jaw chuck to clamp the workpiece, so that the tool vertically arranged below the hydraulic three-jaw chuck processes the bottom of the workpiece, and the hydraulic three-jaw chuck can only clamp shaft parts. If the part to be processed is a planar part, the hydraulic three-jaw chuck cannot grab the part and process it. Utility Model Content

[0004] The utility model aims to solve the problem that the hydraulic three-jaw chuck in the prior art can only clamp shaft parts. If the parts to be processed are planar parts, the hydraulic three-jaw chuck cannot grasp the parts and process them. The utility model provides an inverted moving beam gantry milling machine for processing planar parts.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0006] A template inversion clamping mechanism includes a workbench, and at least one group of clamping modules that can be relatively close to or far away are arranged on the lower surface of the workbench. The clamping modules include a slide embedded in the lower surface of the workbench and slidingly guided, and a clamping claw arranged at the lower end of the slide for lifting. The movement of the slide is controlled by a first driving component, and the lifting and lowering of the clamping claw is controlled by a second driving component.

[0007] By adopting the above scheme, the first driving component can be set to drive the slide to move on the lower surface of the workbench, so that the jaws can move closer to or away from each other, and the second driving component can be set to drive the jaws to move up and down. When the jaws need to clamp the template, the second driving component can be used to drive the jaws to move downward, so that the jaws drop to one or both sides symmetrically of the template. Afterwards, the first driving component is used to control the jaws to approach each other. When the jaws fit the surface of the template, the jaws will clamp the template. Afterwards, the second driving component is used to control the jaws to move upward again, and the template will move upward along with the jaws.

[0008] Preferably, the clamping jaw includes a vertically arranged clamping plate with an upper end connected to the second driving component, and a pressing plate extending vertically from the bottom of the clamping plate toward the center of the workbench and used for inserting into the template groove or the bottom of the template.

[0009] By adopting the above scheme, the set pressure plate can be moved downward under the drive of the second driving component. When the pressure plate drops to the side wall of the template, the pressure plate can gradually approach the template through the first driving component and gradually insert into the groove of the template or gradually insert into the bottom of the template and drive the template to move upward after being inserted into the groove of the template or the bottom of the template, so that the template is pressed between the pressure plate and the lower surface of the workbench, thereby reducing the probability of the template falling from the clamping claws when the clamping claws clamp the template.

[0010] Preferably, the first driving component includes a first cylinder fixedly arranged horizontally on the lower surface of the workbench, and the end of the piston rod of the first cylinder is fixedly connected to the slide seat.

[0011] By adopting the above scheme, the piston rod of the first cylinder and the slide are connected to each other, so that when the piston rod of the first cylinder is extended and retracted under the drive of the first cylinder, the slide is pushed to move on the lower surface of the workbench, thereby realizing the mutual approach or distance between the two clamps.

[0012] Preferably, the second driving component comprises a second cylinder fixedly arranged at one end of the slide away from the workbench, and the telescopic rod of the second cylinder extends vertically downward to form the clamping plate.

[0013] By adopting the above scheme, the telescopic rod of the second cylinder is connected to the pressure plate, so that the telescopic rod is driven by the second cylinder to move the pressure plate up and down, so that the pressure plate can be lowered and gradually inserted into the groove of the template or the bottom of the template, and can drive the template to move upward together during the lifting and lowering, and press the template between the pressure plate and the lower surface of the workbench, thereby reducing the probability of the template falling from the clamp.

[0014] Preferably, an auxiliary adsorption mechanism is provided below the workbench and can adsorb the template to the lower surface of the workbench. The auxiliary adsorption mechanism includes a first electromagnet provided on the lower surface of the workbench and used to adsorb the template.

[0015] By adopting the above scheme, the template can be adsorbed on the lower surface of the workbench by the first electromagnet arranged on the lower surface of the workbench, thereby further reducing the probability of the template detaching from the clamp. At the same time, the first electromagnet can also reduce the extrusion of the template on the pressure plate due to gravity, thereby reducing the probability of damage to the pressure plate and increasing the service life of the pressure plate.

[0016] Preferably, at least one set of clamping modules is provided on each of the two opposite sides of the workbench.

[0017] By adopting the above solution, at least one set of clamping modules is provided on both sides of the workbench, which can further reduce the probability of the template falling off the clamping claws when the clamping claws clamp the template.

[0018] Preferably, a transfer device includes a bed body, which includes a fixed bed frame arranged in parallel, an X-axis movable frame with guides sliding on the fixed bed frame at both ends, a Y-axis movable frame moving horizontally along a moving direction perpendicular to the X-axis movable frame, and a Z-axis movable frame vertically lifted and lowered on the Y-axis movable frame, and the above-mentioned template inversion clamping mechanism is fixed to the bottom of the Z-axis movable frame.

[0019] By adopting the above scheme, the X-axis movable frame can drive the template inversion clamping mechanism arranged below the Z-axis movable frame to move along the X-axis direction, the Y-axis movable frame can drive the template inversion clamping mechanism to move along the Y-axis direction, and the Z-axis movable frame can drive the template inversion clamping mechanism to move down along the Z-axis, so that after the template inversion clamping mechanism clamps the non-circular template, the template is moved to the processing position for processing. Since the template is installed upside down in the template inversion clamping mechanism, when the template moves to the processing position, the tool processes the template from bottom to top, and the debris generated by the template processing will fall downward due to gravity, thereby reducing the time for workers to clean the template surface during template processing, and at the same time, it can also reduce the probability of the tool being damaged by the debris generated by processing.

[0020] Preferably, a workpiece pre-positioning and loading mechanism is provided at one end of the moving travel of the X-axis moving frame.

[0021] Preferably, the workpiece pre-positioning and loading mechanism includes a placement base plate and an electromagnetic adsorption component arranged on the placement base plate, and the electromagnetic adsorption component includes a second electromagnet that can be opposite to at least two diagonals of the lower end surface of the template.

[0022] By adopting the above scheme, the template placed on the placing bottom can be adsorbed by the second electromagnet arranged on the placing base plate. At the same time, the second electromagnet arranged at least opposite to the two diagonals of the lower end face of the template can also provide a reference for the placement position of the template when the worker places the template on the placing base plate.

[0023] Due to the adoption of the above technical solutions, the utility model has significant technical effects: the first driving component is set to drive the slide to move on the lower surface of the workbench, so that the clamps can be moved closer to or farther away from each other, and the second driving component is set to drive the clamps to move up and down. When the clamps need to clamp the template, the second driving component can be used to drive the clamps to move downward, so that the clamps are lowered to one or both sides symmetrical to the template. Afterwards, the first driving component is used to control the clamps to approach each other. When the clamps fit the surface of the template, the clamps will clamp the template. Afterwards, the second driving component is used to control the clamps to move upward again, and the template will move upward along with the clamps. BRIEF DESCRIPTION OF THE DRAWINGS

In this embodiment, four second electromagnets 702 are provided and can simultaneously align the four corners of the template 10.

[0036] After the template 10 is placed on the base plate 9, the position of the template 10 can be checked by means of a meter or the like to check whether the error of the template 10 is less than the allowable range value. If the test is qualified, the template inversion clamping mechanism can be started; if the test is unqualified, the position of the template 10 can be adjusted by manually knocking on the template 10 until the meter test is qualified.

[0037] The process of machining the lower end surface of the template 10 by the transfer and milling machine is as follows:

[0038] 1. Template 10 pre-positioning process:

[0039] 1.1. Pre-adsorption: The second electromagnet 702 is in the energized state, the operator places the template 10 on the bottom plate and the second electromagnet 702 is adsorbed on the corner of the template 10;

[0040] 1.2. Detection of positioning error: The operator uses a meter to detect. If the positioning error is within the allowable range, the meter is qualified and the process goes to step 2. If the positioning error exceeds the allowable range, the meter is unqualified. After manually tapping the template 10 for adjustment, the meter is checked at any time until the test is qualified.

[0041] 2. Transfer and clamping process: Start the first servo motor 1101, so that the first servo motor 1101 drives the workbench 1 to move to the top of the bottom plate 9, then start the third servo motor 1301, so that the third servo motor 1301 drives the workbench 1 to move downward until the first electromagnet 701 on the lower surface of the workbench 1 is in contact with the upper surface of the template 10. At this time, the first electromagnet 701 will adsorb the template 10 on the lower surface of the workbench 1, then start the second cylinder 502, so that the second cylinder 502 drives the pressure plate 4 to move downward, so that the pressure plate 4 is lower than the top wall of the groove in the template 10, then start The first cylinder 501 causes the pressing plate 4 to gradually be inserted into the groove of the template 10. When the pressing plate 4 is inserted into the groove of the template 10, the second electromagnet 702 is controlled to lose power, causing it to lose its adsorption of the template 10. Then, the second cylinder 502 is used again to control the pressing plate 4 to rise. At this time, the template 10 will be partially pressed between the pressing plate 4 and the lower surface of the workbench 1. Then, the third servo motor 1301 is controlled to drive the workbench 1 to move upward. At this time, the template 10 will gradually separate from the placement base plate 9. Then, the first servo motor 1101 is controlled to drive the workbench 1 and the template 10 on the lower surface of the workbench 1 to move to the processing station.

[0042] 3. Processing process of template 10: After template 10 is moved above the milling machine tool, the milling machine processes the lower end of template 10 according to the program.
