Description

Technical Field

[0001] This utility model belongs to the field of conveying mechanism technology, and more specifically relates to a chain synchronous conveying mechanism. Background Technology

[0002] The cleaning process for complex parts requires different cleaning steps, such as high and low pressure rinsing, air drying, vacuum drying, centrifugal drying, and testing. Parts need to be transferred between various workstations. The traditional method is to transfer them manually by moving the positioning fixture containing the parts to the workstation. After the positioning fixture is placed, its position needs to be calibrated, which is inefficient and has high labor costs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a chain synchronous conveying mechanism that enables the synchronous conveying of parts at each workstation, thereby improving the transfer efficiency of parts at each workstation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a chain synchronous conveying mechanism, including a support base, on which a positioning fixture for positioning parts is provided, and the positioning fixture is slidably connected to the support base. Drive chains are provided on both sides of the support base, and a conveying push rod is provided between the two drive chains. The conveying push rod contacts the positioning fixture, and the drive chains are connected to a drive mechanism. Each pair of conveying push rods constitutes a workstation.

[0005] Furthermore, a pair of roller sets are provided on the support base. Each roller set includes a roller bracket and several rollers. The positioning fixture is placed on the roller set, and the rolling of the rollers reduces the friction when the positioning fixture moves.

[0006] Furthermore, a guide rod is provided on one side of the roller assembly, and a guide block corresponding to the guide rod is provided on the positioning fixture.

[0007] Furthermore, the support base extends along the running direction of the drive chain, and several pairs of roller groups are provided on the support base. There is a gap between each pair of roller groups. The length of the gap is less than half the length of the roller bracket, and the length of the gap is greater than the diameter of the conveying push rod.

[0008] Furthermore, the conveying push rods are in pairs, with a gap between the two conveying push rods, the length of which is greater than the width of the two conveying push rods.

[0009] Furthermore, the drive mechanism includes a drive sprocket and a driven sprocket located at both ends of the drive chain, and the drive sprocket is connected to a servo motor.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the drive mechanism drives the drive chain to run in a cycle, that is, when the conveying push rod between the two drive chains contacts the positioning fixture, it can drive the positioning fixture to move on the support base, so that the positioning fixture is carried to the work station, and the parts are processed by the equipment at the work station, realizing the synchronous conveying of parts at each work station and improving the transfer efficiency of parts at each work station.

[0015] Reference Figure 1 and Figure 2 The present invention will be further described below.

[0016] The chain synchronous conveying mechanism includes a support base 1, on which a positioning fixture 2 for positioning parts is provided, and the positioning fixture 2 is slidably connected to the support base 1. Drive chains 3 are provided on both sides of the support base 1, and a conveying push rod 4 is provided between the two drive chains 3. The conveying push rod 4 contacts the positioning fixture 2, and the drive chains 3 are connected to the drive mechanism. Each two conveying push rods 4 constitute a work station.

[0017] like Figure 1 and Figure 2 As shown, the drive mechanism drives the drive chain 3 to run in a cycle. When the conveying push rod 4 between the two drive chains 3 contacts the positioning fixture 2, it can drive the positioning fixture 2 to move on the support base 1, so that the positioning fixture 2 is moved to the workstation and the parts are processed by the equipment at the workstation. This realizes the synchronous conveying of parts at each workstation and improves the transfer efficiency of parts at each workstation.

[0018] like Figure 1 As shown, specifically, the drive chain 3 is a double chain.

[0019] like Figure 1 As shown in this example, preferably, the support base 1 is provided with a pair of roller groups 5, each roller group 5 including a roller bracket and several rollers, and the positioning fixture 2 is placed on the roller group 5, and the rolling of the rollers reduces the friction when the positioning fixture 2 moves.

[0020] like Figure 1 As shown in this example, preferably, a guide rod 6 is provided on one side of the roller assembly 5, and a guide block corresponding to the guide rod 6 is provided on the positioning fixture 2, so as to prevent the positioning fixture 2 from shifting when it moves by means of the guide rod 6.

[0021] like Figure 2 As shown, specifically, the guide rod 6 is located on the upper side of the roller assembly 5.

[0022] like Figure 1 As shown in the preferred embodiment, the support base 1 extends along the running direction of the drive chain 3. Several pairs of roller groups 5 are provided on the support base 1, and a gap 7 is provided between each pair of roller groups 5. The length of the gap 7 is less than half the length of the roller bracket, and the length of the gap 7 is greater than the diameter of the conveying push rod 4. That is, the gap 7 is used to place the conveying push rod 4. After the conveying push rod 4 pushes the positioning fixture 2 to a work position, it retracts to the middle of the gap 7, so that a certain distance is maintained between the conveying push rod 4 and the positioning fixture 2, so as to avoid interference between the processing equipment and the conveying push rod 4 during processing.

[0023] like Figure 1As shown, in this example, preferably, the conveying push rod 4 is in a group of two, with a gap between the two conveying push rods 4, and the length of the gap 7 is greater than the width of the two conveying push rods 4.

[0024] In this preferred embodiment, the driving mechanism includes a driving sprocket and a driven sprocket located at both ends of the driving chain 3. The driving sprocket is connected to a servo motor, which drives the driving chain 3 to run. The servo motor enables the conveying push rod 4 to push the positioning fixture 2 to an accurate distance.

[0025] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
