Embodiment 1

[0025] Such as figure 1 , figure 2 , image 3 it is good Figure 4 As shown, a synchronous pulley fixing mechanism includes a storage table 2 and a plurality of fixing devices 1. The number of T-shaped slots equal to the number of the fixing devices 1 is provided on the storage table 2, and the T-shaped slots have the same common end, the fixing device 1 includes a first support block 101, a pressing plate 102, a second support block 103 and a compression bolt 104, the lower end of the second support block 103 is provided with a first T-shaped protrusion, and each fixing device The first T-shaped protrusions of 1 are respectively arranged in a T-shaped groove, and one end of the second support block 103 is also provided with a rack-shaped outer protrusion in the vertical direction, and the nut of each compression bolt 104 Both ends are located in a T-shaped slot, each pressing plate 102 is provided with a bolt through hole, the first support block 103 is located on the sto...

Embodiment 2

[0028] This embodiment is further improved on the basis of embodiment 1, as figure 1 , figure 2 , image 3 it is good Figure 4 As shown, the lower part of each first support block 101 is provided with a second T-shaped protrusion, and the second T-shaped protrusion is located in the T-shaped groove.

[0029] The provided second T-shaped protrusion facilitates the limitation of the first support block 101 in the T-shaped slot, which is beneficial to the management of the components of the present invention.

[0030] There are three T-shaped slots and three fixing devices 1 .

[0031] Three T-shaped slots and three fixing devices 1 can provide a stable clamping station for the synchronous pulley, and this setting aims at simplifying the present invention under the premise of satisfying functions.

[0032] The included angles between the T-shaped slots are all 120°.

[0033] The included angles between the T-shaped slots are set to be 120°, and the fixed points of the sync...

Abstract

The invention discloses a synchronous belt pulley fixing mechanism which comprises an accommodating table and a plurality of fixing devices. T-shaped grooves are formed in the accommodating table, the quantity of the T-shaped groove is equal to that of the fixing devices, each fixing device comprises a first support block, a pressure plate, a second support block and a holddown bolt, a first T-shaped protrusion is arranged at the lower end of each second support block, a rack-shaped outer protrusion is further vertically arranged at one end of each second support block, a bolt through hole is formed in each pressure plate, and a scale block is arranged on an optional fixing device. The synchronous belt pulley fixing mechanism has the advantages that the synchronous belt pulley fixing mechanism is simple in structure and convenient to manufacture and use; damage to racks of synchronous belts can be prevented when the synchronous belt pulleys are fixed by the aid of the synchronous belt pulley fixing mechanism, and the influence on chip removing processing on the end surfaces of the synchronous belt pulleys can be prevented when the synchronous belt pulleys are fixed by the aid of the synchronous belt pulley fixing mechanism; the heights of the synchronous belt pulleys can be advantageously checked by production personnel at any time owing to the scale block, so that the synchronous belt pulleys which meet requirements on processing dimensions can be acquired advantageously.

Description

technical field [0001] The invention relates to the field of synchronous pulley manufacturing equipment, in particular to a synchronous pulley fixing mechanism. Background technique [0002] The last process in the manufacture of timing pulleys is to remove the burrs left on both sides of the timing pulleys after the rack processing is completed. In the prior art, the methods for removing this burr mainly include manual grinding by production personnel, lathe turning and milling by using a milling machine or a drilling machine. In the above-mentioned manual grinding and lathe turning, the operator generally uses a bench vise and a chuck to The synchronous pulley is fixed, but the contact surface of the bench vise, chuck and synchronous pulley is the side of the synchronous pulley. Too tight clamping will damage the rack of the synchronous pulley, and too loose clamping will affect the grinding or turning. The stability of the synchronous pulley; the fixation of the synchron...
