[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0014] As Figure 1-2 shown, the embodiments of the present utility model include:

[0015] A synchronous belt fitting, comprising a pair of first tooth plates 1, second tooth plates 2, and a pair of first mounting plates 3, second mounting plates 4. The first tooth plates 1 are aligned and joined together at the bottom surface of the first mounting plates 3 by a plurality of Z-axis bolts 5. The second tooth plates 2 are aligned and joined together at the bottom surface of the second mounting plates 4 by a plurality of Z-axis bolts 5. The first mounting plates 3 and the second mounting plates 4 are aligned and spliced by a plurality of X-axis bolts 6. The first tooth plates 1 and the second tooth plates 2 are aligned and spliced by a plurality of X-axis bolts 6. The first tooth plates 1, second tooth plates 2, first mounting plates 3, and second mounting plates 4 form a cross-shaped joint seam composed of a horizontal channel and a vertical channel, and the horizontal channel is used to clamp the synchronous belt 100.

[0016] Among them, the first tooth plates 1, second tooth plates 2, first mounting plates 3, and second mounting plates 4 are all L-shaped structures.

[0017] Furthermore, the first mounting plates 3 are provided with first brackets 7 obliquely facing the first tooth plates 1 at one end of the horizontal channel, and the second mounting plates 4 are provided with second brackets 8 obliquely facing the second tooth plates 2 at the other end of the horizontal channel; the first tooth plates 1 are provided with first swing arms 9 obliquely facing the first mounting plates 3 at one end of the horizontal channel, and the second tooth plates 2 are provided with second swing arms 10 obliquely facing the second mounting plates 4 at the other end of the horizontal channel. Y-axis bolts 11 are respectively connected between the first swing arms 9 and the first brackets 7, and between the second swing arms 10 and the second brackets 8.

[0018] Furthermore, an upper scale 12a perpendicular to the vertical channel is provided on the first mounting plate 3 or the second mounting plate 4, and a lower scale 12b perpendicular to the vertical channel is provided on the first tooth plate 1 or the second tooth plate 2.

[0019] Furthermore, convex teeth facing the first mounting plate 3 or the second mounting plate 4 are provided on both the first tooth plates 1 and the second tooth plates 2.

[0020] This product is used to dock two synchronous belts 100. The first mounting plates 3 and the second mounting plates 4 are metal parts, and mounting holes can be customized and processed on them to be connected with workpieces, so as to realize the synchronous movement of the workpieces and the synchronous belts 100.

[0021] As Figure 1 shown, the first mounting plate 3 presses the synchronous belt 100 at the left end on the first tooth plate 1, and the second mounting plate 4 presses the synchronous belt 100 at the right end on the second tooth plate 2. In order to prevent the synchronous belt 100 from skipping teeth, the tension can be adjusted by the Z-axis bolts 5 to lock the mounting plate and the tooth plate. Thus, there is no need to use a circular synchronous belt 100. Just use one synchronous belt 100, install the accessory group at the head and tail, and tighten it with screws, which is convenient for replacing the synchronous belt 100.

[0022] To achieve the docking at both ends of the synchronous belt 100 and the adjustment of the tension force, the first mounting plate 3 and the second mounting plate 4 are locked and joined together by the X-axis bolts 6, and the first toothed plate 1 and the second toothed plate 2 are also locked and joined together by the X-axis bolts 6. Thus, there is no need to add an idler pulley for tensioning, and the tension can be conveniently adjusted.

[0023] To avoid the skew of the two synchronous belts 100, "the first bracket 7 and the first swing arm 9", and "the second bracket 8 and the second swing arm 10" that cooperate with each other are respectively added at the four corners of the horizontal channel, so as to reduce the shear force (tearing) caused by the skew docking at both ends of the synchronous belt 100.

[0024] To facilitate daily maintenance and repair, a straight ruler is provided at each of the upper and lower ends of the vertical channel, that is, the upper measuring ruler 12a and the lower measuring ruler 12b mentioned above. The distance of the vertical channel can be detected by the observation method, and the faults caused by the fatigue of the synchronous belt 100 or the connecting parts can be found in time.

[0025] This product is applicable to reciprocating motion, and the stroke of the workpiece should be less than "the center distance between the two shafts - the number of mounting plates * the length of the mounting plate".

[0026] This product can be used in a variety of ways.

[0027] Usage 1: Only used for synchronizing workpieces:

[0028] Fit the toothed plate to the tooth profile of the synchronous belt 100, and fit the mounting plate to the back of the synchronous belt 100. Then tighten it with bolts. Subsequently, the workpiece can be installed on the mounting plate with bolts. The hole positions and sizes of the mounting threaded holes can be customized.

[0029] Usage 2: Used for tensioning the synchronous belt 100, connecting the head and tail of one synchronous belt 100, and synchronizing workpieces:

[0030] Respectively fit the toothed plate to the tooth profile of the synchronous belt 100 at the head and tail, and fit the mounting plate to the back of the synchronous belt 100. Then tighten it with bolts to form a loop to tension the synchronous belt 100.

[0031] In summary, the present utility model provides a synchronous belt 100 fitting. Two mounting plates and two toothed plates are used to construct a cross seam with bolts in the XYZ three-axis directions, and the synchronous belt 100 can be tensioned and adjusted in the horizontal channel and the vertical channel. It has the advantages of simple product structure and convenient daily maintenance.
