Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tooling fixture, in particular to a universal feeding and discharging device for iron wood disc skeleton, steamer frame and outer ring. BACKGROUND

[0002] With the development of domestic modernization, the demand for power cables is increasing, and so is the demand for iron wood disc (cable disc) used for cable reel.

[0003] The iron wood disc is composed of a pair of iron wood discs connected by a spool, as shown in the iron wood disc skeleton in the drawing. Figure 5 The skeleton is composed of an outer ring 101 and a middle steamer frame 102, and the final iron wood disc is obtained after installing a wooden board on the surface of the skeleton. The steamer frame is named as such because of its similar structure to the steamer frame used for cooking. The frame structure composed of a concentric shaft core 103 and an inner ring 104, as well as a plurality of radial spokes 105, is welded together to form a "steamer frame". The outer ring 101 is welded to the outer edge of the steamer frame, and is concentric with the shaft core 103 and the inner ring 104.

[0004] According to the diameter of the iron wood disc, the inner ring can be omitted or one or more concentric rings of different diameters can be used. The spokes 105 can be made of angle steel, and the inner ring 104 can be made by bending the angle steel with a bending machine and welding the two ends. The shaft core 103 can be made by connecting a steel pipe to a ring-shaped thin plate (flange piece). During the welding operation, one end of the spoke 105 is placed on the flange piece and tightly against the outer wall of the shaft core 103, and then the inner ring 104 is placed on the top surface of the radial spokes 105, ensuring that the inner ring 104 and the shaft core 103 are concentric.

[0005] Currently, the production of iron wood discs is mainly manual, and usually the iron disc is first produced and then the wooden board is installed on the iron disc. During the production of the iron wood disc, the steamer frame and the outer ring are first welded together, and then manually transported to the corresponding workbench for the process of installing the wooden board. The whole process relies on manual labor, which is labor-intensive for the operator, and there is a risk of injury to the worker if attention is not paid. SUMMARY

[0006] The present application provides a universal feeding and discharging device for iron wood disc skeleton, steamer frame and outer ring to solve the above problems. Specifically, the universal feeding and discharging device for iron wood disc skeleton, steamer frame and outer ring includes a carrying manipulator and a workpiece clamp.

[0007] The workpiece clamp includes a clamp frame, a power source, a clamping jaw and a clamping jaw driving mechanism.

[0008] The fixture frame is a rectangular frame structure; the clamping jaws are left-right symmetrical in two groups, which are respectively connected and driven by the left clamping jaw driving mechanism and the right clamping jaw driving mechanism, and the power input ends of the left and right clamping jaw driving mechanisms are connected to the power output end of the power source; the left clamping jaw and the left clamping jaw driving mechanism are mirror-symmetrical with the right clamping jaw and the right clamping jaw driving mechanism, and the left clamping jaw and the right clamping jaw move synchronously in opposite directions (synchronous closing or moving away).

[0009] For the left clamping jaw and the left clamping jaw driving mechanism (since the left and right clamping jaws and the clamping jaw driving mechanism are mirror-symmetrical, the mirror image structure on the right is not repeated) : the main body of the left clamping jaw is located below the fixture frame; the left clamping jaw driving mechanism includes a lead screw device, the lead screw of the lead screw device is connected to the fixture frame through a pair of bearing devices, and is above the fixture frame; the nut of the lead screw device is connected to the clamping jaw through a clamping jaw connecting block, and the main body of the clamping jaw connecting block is in the hollow of the fixture frame.

[0010] The left and right clamping jaws enclose a workpiece clamping area.

[0011] By using the utility model, the iron wood disc skeleton, the steamer rack or the outer ring is clamped by the workpiece clamp, and the workpiece clamp is moved to the required position by the carrying manipulator. Since the iron wood disc skeleton, the steamer rack and the outer ring are all center-symmetrical workpieces and have large diameters, under the main body structure of the rectangular frame, the left and right two groups of clamping jaws are driven by the lead screw device to move from left and right sides to close until clamping the workpiece, so that the clamping action requirement of the large-span clamping jaw can be met. The workpiece clamping area of the traditional clamping jaw is narrow, and the traditional clamping jaw with a large clamping area has a large weight, so it is not suitable for clamping the iron wood disc skeleton and other related workpieces.

[0012] Further, a clamping guide positioning mechanism is further connected below the middle position of the fixture frame, which includes a center and a center extension mechanism; the center is vertically downward, and the axis of the center passes through the center of the workpiece clamping area; the center extension mechanism connects and drives the center to make vertical extension and retraction actions.

[0013] The structure is mainly used for clamping the iron wood disc skeleton or the steamer rack, and the center is pressed downward to penetrate into the hollow of the shaft core 103, so that the workpiece clamping area realizes "centering" during operation.

[0014] Further, for the left clamping jaw and the left clamping jaw driving mechanism: a guide rail is connected to the fixture frame, and the guide rail is parallel to the lead screw; a sliding block is slidably connected to the guide rail; the sliding block and the nut are connected through a nut sliding block connecting block, and the clamping jaw connecting block is connected to the bottom of the nut sliding block connecting block. Similarly, the right clamping jaw and the right clamping jaw driving mechanism which are mirror-symmetrical have these structures.

[0015] Here, the main body of the nut sliding block connecting block can be L-shaped, the short side of the L-shaped is attached to the side surface of the nut, the long side of the L-shaped is attached to the end of the sliding block, and the clamping jaw connecting block is connected to the main body of the long side of the L-shaped.

[0016] Further, the structure of the clamping jaw is that the vertical rod is connected with the baffle at the bottom surface, and the projection of the vertical rod on the bottom surface is within the range of the baffle. The baffle with a larger range supports the lower part of the edge of the workpiece.

[0017] Further, in the guide positioning mechanism of the clamp, the top pin telescopic mechanism comprises a cylinder, guide shafts and a pressing plate; the guide shafts are arranged on the left and right sides of the cylinder; the bottom surface of the guide shafts is connected with the pressing plate, and the bottom surface of the pressing plate is connected with the top pin; the two guide shafts are connected to the equipment support plate through linear bearings respectively, and the equipment support plate is connected to the hollow of the clamp frame. In this structure, the vertical movement of the top pin is stable.

[0018] In cooperation with the baffle on the clamping jaw, the shaft core is pressed by the pressing plate, and the baffle supports the edge of the workpiece, so that the overall grabbing structure is stable.

[0019] Specifically, for the left clamping jaw and the left clamping jaw driving mechanism: a group of left clamping jaws comprises two clamping jaws, the distance between the two clamping jaws is greater than 0, and the line connecting the two clamping jaws is perpendicular to the axis of the lead screw; the four clamping jaws of the left and right clamping jaws are sequentially connected to form a rectangular area, and the axis of the top pin passes through the center of the rectangle.

[0020] The power source is a motor, the motor is connected to the hollow of the clamp frame through the equipment support plate; the output shaft of the motor is connected and drives the lead screw device of the left and right clamping jaw driving mechanisms through a transmission device (such as a shaft coupling); the mechanical hand connecting mechanism is connected above the equipment support plate.

[0021] The mechanical hand connecting mechanism is a mechanical hand connecting plate, and the carrying mechanical hand is detachably connected to the smooth surface of the mechanical hand connecting plate through an electromagnetic suction cup. At this time, the motor is in the cavity between the equipment support plate and the mechanical hand connecting plate.

[0022] In engineering applications, the parts that need to be in contact with the workpiece, such as the vertical rod, the baffle, and the pressing plate, can be made of steel pipes, steel plates and other materials with sufficient structural strength and unit weight. Further, a rubber layer or other buffer protection layer can be wrapped outside the contact position of the steel pipe, steel plate and the workpiece.

[0023] In the prior art, manpower is required to sequentially carry the shaft core 103, the inner ring 104, the outer ring 101, the plurality of spokes 105 and the flange sheet to a welding workbench for group welding, and the welded iron disc sheet also needs to be manually carried to a corresponding workbench for next process processing. This way, the operation worker has a large labor intensity, low automation degree and safety hazards of iron disc bruising workers.

[0024] Compared with the prior art, the beneficial effects of the utility model are:

[0025] 1. The utility model discloses convenient operation, and manual handling steamer frame and outer ring of operator is not needed again, and the labor intensity of operator is reduced.

[0026] 2. The workpiece clamp can realize that steamer frame is carried to the machining workbench by the manipulator, improves the efficiency of making the iron wood disc skeleton, and helps realizing automatic welding of the iron wood disc skeleton. BRIEF DESCRIPTION OF DRAWINGS

Similarly, the right clamping jaw and the right clamping jaw driving mechanism, which are mirror-symmetrically connected, also have the same structure.

[0046] The structure of the clamping jaw 19 is that the vertical rod is connected with the baffle 27 at the bottom surface, and the projection of the vertical rod on the bottom surface is within the range of the baffle.

[0047] For the left clamping jaw and the left clamping jaw driving mechanism: a set of left clamping jaws has two clamping jaws, the distance between the two clamping jaws is greater than 0, and the line connecting the two clamping jaws is perpendicular to the axis of the lead screw. Similarly, the right clamping jaw and the right clamping jaw driving mechanism are also mirror-symmetrically structured.

[0048] The four clamping jaws of the left and right clamping jaws are sequentially connected to form a rectangular area, and the axis of the center point 23 passes through the center of the rectangle.

[0053] In the utility model:

[0054] The mechanical hand connecting plate 8 is used for connecting the carrying mechanical hand 24. The left-rotating lead screw 2 and the right-rotating lead screw 11 are driven to rotate by the servo motor 7.
