Abstract
The utility model provides a brake device capable of removing clearance. The brake device capable of removing the clearance comprises a box body and a divider. The box body is provided with a main shaft, and the main shaft is provided with a brake wheel. An output shaft of the divider is connected with a driving duplex chain wheel, and the driving duplex chain wheel is connected with a driven duplex chain wheel which is installed on the main shaft through a chain. The brake wheel is connected with a cam, a bearing is arranged at the lower end of the cam, and the bearing is connected with an eccentric pin roll. The brake wheel is provided with a brake band, one end of the brake band is connected with a long fixed seat which is fixedly installed on the box body, and the other end of the brake band is connected with a swing block. The swing block is connected with a short fixed seat which is fixedly installed on the box body. The swing block is connected with a screw which is fixedly arranged on the box body, and a spring is installed at the lower end of the screw. The brake device capable of removing the clearance is simple in structure and low in cost, the influence of inaccurate positioning of the divider is completely avoided, and the brake device is used for achieving the fact that a common divider can have the performance of the divider with high precision.
Description
Technical field
The utility model belongs to mechanical field, relates in particular to a kind of brake gear of eliminating the gap.
Background technology
Milling word is a kind of processing technology of aluminium matter anti-fake bottle lid, thickness is that the aluminium sheet of 0.18-0.24mm is after coating and printing (top pattern), first aluminium sheet is drawn into bottle cap (aluminum barrel), then after the aluminum barrel side rolls out the convex printed words, again convex surfaces is carried out the micro-milling of 0.05-0.1mm.Have light, characteristics attractive in appearance through the bottle cap that mills word.The list of present domestic use, although double-head automatic character milling machine has realized milling the automation of word, but because dispenser output shaft and rotating disk are to be rigidly connected, decide incessantly position after easily producing calibration, index dial is wriggled in a circumferential direction, therefore high to the required precision of dispenser, domestic dispenser is difficult to reach required precision, therefore (price of the Taiwan import high accuracy dispenser of every same model is about 1.5 ten thousand for many employing import dispensers, Japan, Italy produce up to every about 30,000 yuan, and domestic common dispenser price is about 3000 yuan), this just causes the rapid increase of equipment cost.
Summary of the invention
The utility model provides a kind of brake gear of eliminating the gap, has solved the inaccurate shortcoming in dispenser location in the background technology.
The technical solution of the utility model is achieved in that a kind of brake gear of eliminating the gap, comprise casing, dispenser, be equipped with main shaft on the casing, be equipped with brake wheel on the main shaft, the output shaft of dispenser is connected with the active duplex chain wheel, initiatively duplex chain wheel is connected with driven duplex chain wheel on being installed in main shaft by chain, brake wheel is connected with cam, the cam lower end is provided with bearing, bearing links to each other with eccentric pin shaft, establishes brake ribbon on the brake wheel, and brake ribbon one end links to each other with long holder on being fixedly mounted on casing, the other end links to each other with swing block, and swing block links to each other with short holder on being fixedly mounted on casing;
Swing block links to each other with screw rod on being fixed on casing, and the screw rod lower end is equipped with spring.
The beneficial effects of the utility model are: the utility model is simple in structure, cost is low, cleverly the wriggling behind the dispenser output shaft location has been passed to chain, because chain is flexible member, has dissolved a small amount of wriggling amount of dispenser main shaft fully, the chain transmission is less than on the driven sprocket, brake wheel is stopped tightly simultaneously, main shaft stably is parked in mills on the word location, avoided the inaccurate impact in dispenser location fully, utilize brake gear can make common dispenser realize the performance of high accuracy dispenser.

Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model.
Part explanation: 1, casing, 2, brake wheel, 3, driven duplex chain wheel, 4, main shaft, 5, cam, 6, eccentric pin shaft, 7, dispenser, 8, duplex chain wheel initiatively, 9, long holder, 10, brake ribbon, 11, swing block, 12, screw rod, 13, spring, 14, short holder, 15, bearing.
The specific embodiment
1-3 is further described the utility model below in conjunction with accompanying drawing: a kind of brake gear of eliminating the gap, comprise casing 1, dispenser 7, be equipped with main shaft 4 on the casing 1, be equipped with brake wheel 2 on the main shaft 4, the output shaft of dispenser 7 is connected with active duplex chain wheel 8, initiatively duplex chain wheel 8 is connected with driven duplex chain wheel 3 on being installed in main shaft 4 by chain, brake wheel 2 is connected with cam 5, cam 5 lower ends are provided with bearing 15, bearing 15 links to each other with eccentric pin shaft 6, establish brake ribbon 10 on the brake wheel 2, brake ribbon 10 1 ends link to each other with long holder 9 on being fixedly mounted on casing 1, and the other end links to each other with swing block 11, and swing block 11 links to each other with short holder 14 on being fixedly mounted on casing 1, swing block 11 links to each other with screw rod 12 on being fixed on casing 1, and screw rod 12 lower ends are equipped with spring 13.
When driving main shaft 4 under the drive of active duplex chain wheel 8, driven duplex chain wheel 3 rotates, bossing on the cam 5 contacts with bearing 15, long holder 9 and short holder 14 maintain static, swing block 11 tension brake ribbons 10 play the effect of brake, and the sunk part on cam 5 contacts with bearing 15, swing block 11 is lax, loose state also appears in brake ribbon 10, brakes inoperative, and main shaft 4 begins to turn to next time location.Tighten the degree of tightness that spring 13 can be adjusted swing block 11 by screw rod 12.Can adjust the contact position of bearing 15 and cam 5 by eccentric pin shaft 6.
