Abstract
The utility model provides a plate grinder, which is mainly used for grinding test plates used in test cabinets and laboratories. The utility model is provided with a supporting frame 7, and the upper bearing of the supporting frame 7 is connected with a bidirectional threaded rod 12. The plate grinder is fixedly connected with a bedplate 1 which is in parallel with the bidirectional threaded rod 12 and is made of steel or cast-iron materials. A bidirectional nut 11 which is matched with the bidirectional threaded rod 12 is connected with a drive pin 4, and the drive pin 4 is inserted into the hole on a carriage 3 which is arranged on the bedplate 1. A magnet 5 is embedded in the carriage 3, and the carriage 3 is also provided with a groove filled with a vertical piece; the bidirectional threaded rod 12 is connected with an electrical machine 8. The utility model has the advantages of high speed and good quality.
Description
The utility model belongs to a kind of Plate grinder, is mainly used in to polish laboratory, the employed test plate (panel) of laboratory.
Test plate (panel) is staff's necessary tool of laboratory, laboratory, requires smooth smooth.Adopt manual method that test plate (panel) is gone up polishing at sand paper (cloth) before use, manual nog plate is not only wasted time and energy, and the test plate (panel) thickness of slab after repeatedly polishing is inhomogeneous, whole plate face injustice.Because each firmly different, its fineness is also variant simultaneously.
The purpose of this utility model provides fast, smooth smooth, the easy to operate Plate grinder of a kind of nog plate speed.
Technical solution of the present utility model is: a kind of Plate grinder is characterized in that: be provided with support, the support upper bearing (metal) is connected with reverse-flighted screw.Being fixedly connected parallel with reverse-flighted screw is the platen of material with steel or cast iron, the two-way nut that is complementary with reverse-flighted screw is connected to drive pin, drive pin inserts in the hole on the planker place above the platen, also be inlaid with magnet on the planker, and being provided with the groove of adorning test plate (panel), reverse-flighted screw and motor join.
Described platen two ends also are provided with eccentric clamping device.
The utility model is compared with existing manual operations, have fast, smooth smooth, the easy to operate advantage of polishing speed, and cost simple in structure is low.
Below in conjunction with the drawings and the specific embodiments the utility model is further described:
Fig. 1 is the utility model specific embodiment structural representation;
Fig. 2 is a section cross-sectional schematic shown in Figure 1.
As shown in Figure 1, 2: 7 is support, can adopt the shaped steel welding production, and reverse-flighted screw 12 is housed on support 7, and bearing (referring to Fig. 1) is housed between the two ends of reverse-flighted screw 12 and the support 7.The right-hand member head of reverse-flighted screw 12 joins with the motor 8 that is bolted on the support 7, shaft coupling can be housed between the two, also can be provided with decelerator or other transmission device (comprising gear drive etc.).Described reverse-flighted screw 12 is to have left-handed and the screw rod dextrorotation groove.The structure of the two-way nut 11 that is complementary with reverse-flighted screw 12 is: activity is connected to a guiding fork 14 on nut body 13, groove coupling on guiding fork 14 and the reverse-flighted screw 12, when screw rod 12 rotations, guiding fork 14 moves along the groove on the reverse-flighted screw 12, because reverse-flighted screw 12 can only rotate with respect to support 7, and can not move axially, therefore, guiding fork 14 both can drive nut body 13 and move.On support 7, go back longitudinal screw and be connected with the guide shaft 6 parallel with reverse-flighted screw 12, guide shaft 6 penetrates in the hole on the two-way nut 11, to guarantee that two-way nut 11 steadily moves along guide shaft 6, support 7 upper end bolts are connected with the cast iron platen 1 parallel with reverse-flighted screw 12, the dual-side of platen 1 is provided with slotted hole 15, drive pin 4 is by slotted hole 15 and two-way nut 11 screw attachment, and the upper end of drive pin 4 inserts in the circular hole 16 that is complementary with drive pin 4 on the planker 3.The two ends of planker 3 fixedly are inlaid with permanent magnet 5, the bottom surface, middle part of planker 3 is provided with a groove that is complementary with test plate (panel) 10, on platen 1, lay sand paper (cloth) 2, can be close to platen 1 in order to make sand paper (cloth) 2, be provided with an eccentric clamping device 17 at the two ends of platen 1, its structure is: be connected with a bearing support in platen 1 bolts at two ends, the eccentric wheel of a band handle is housed on it, when rotating eccentric wheel, both can compress or unclamp sand paper (cloth) 2.
Its course of work is: at first sand paper (cloth) 2 is tiled on the platen 1, rotates eccentric wheel, make sand paper 2 clamped, test plate (panel) 10 is placed in the groove on the planker 3, and place above the sand paper 2, in the circular hole 16 that the drive pin 4 that joins with two-way nut inserts on the plankers 3.Owing to be inlaid with magnet 5 on the planker 3, therefore tightly be adsorbed on the platen 1, make the enough normal pressures of generation between test plate (panel) 10 and the sand paper 2.When motor 8 energisings, when driving reverse-flighted screw 12 rotations, to stir plectane 3 by two-way nut 11, drive pin 4 and move back and forth along platen 1, test plate (panel) 10 is subjected to evenly strong the friction with sand paper 2 phase-contact surfaces, reaches smooth smooth purpose.
