Description

Technical Field

[0001] The invention relates to the technical field of bolt processing, in particular to a bolt processing manipulator with a movable chassis. Background Art

[0002] A bolt is a mechanical part consisting of a head and a screw. It needs to be used with a nut to fasten two parts with through holes.

[0003] Bolts are classified in many ways according to the force mode of connection, head shape, thread length, thread profile and performance level. For example, according to the head shape, they can be divided into hexagonal head, round head, square head, countersunk head, etc. Among them, hexagonal head bolts are widely used in construction engineering and automotive industry because of their convenient tightening and disassembly.

[0004] After the bolts are produced, auxiliary grinding operations need to be performed on their ends. Currently, there is no suitable bolt clamping device, which makes the grinding operation difficult.

[0005] In view of the above-mentioned defects, the designer actively conducts research and innovation in order to create a bolt processing robot with a mobile chassis to make it more valuable for industrial use. Summary of the invention

[0006] In order to solve the above technical problems, an object of the present invention is to provide a bolt processing robot with a mobile chassis.

[0007] A bolt processing robot with a mobile chassis of the present invention includes a base in contact with the foundation, two parallel guide rails are installed on the upper end of the base, the lower part of the mounting plate cooperates with the guide rails through a slider, the mounting plate is provided with a driving motor for driving the mounting plate to move, the middle part of the mounting plate is installed with a robot body, a "T"-shaped adapter plate is installed at the end of the robot body, and bolt clamping seats are installed at the front end and both sides of the adapter plate.

[0008] This bolt processing robot with a mobile chassis has a robot body mounted on a mounting plate, which is driven by a drive motor to move forward and backward to drive the robot to any position for convenient bolt clamping. The bolt clamping seat mounted on the robot body facilitates the fixing of the bolt.

[0009] Furthermore, the bolt clamping seat is fixed to the adapter frame at the end of the adapter plate, and connecting plates are fixed on both sides of the adapter frame. A claw cylinder is installed on the connecting plate, and two clamping claws are installed on the claw cylinder.

[0010] The claw cylinder on the bolt clamping seat drives two clamping claws to clamp the bolt.

[0011] Furthermore, a plurality of guide sleeves are fixed below the connecting plate, a guide rod is inserted into the guide sleeve, a cylinder mounting plate is fixed to the lower end of the guide rod, and the claw cylinder is fixed on the cylinder mounting plate.

[0012] The installation method of the guide sleeve and the guide rod facilitates the up and down movement of the cylinder mounting plate and plays a buffering role.

[0013] Furthermore, a spring is sleeved on the outer side of the guide sleeve, and the upper and lower ends of the spring are in contact with the mounting plate and the cylinder mounting plate respectively.

[0014] The spring sleeved on the guide sleeve has a buffering capability, avoids hard connection, and protects the claw cylinder.

[0015] Furthermore, a limit plate is fixed on the mounting plate at a position corresponding to the guide sleeve, and a through hole is provided in the middle of the limit plate for the guide rod to pass through, and the guide rod passes through the limit plate and the end portion thereof is screwed into a nut.

[0016] The guide rod passes through the limit plate on the mounting plate, and the guide rod can move slightly on the fiberboard to play a buffering role. The nut at the tail end of the guide rod prevents the guide rod from completely sliding into the guide sleeve.

[0017] Furthermore, a guide rod is fixed on one of the clamping claws via a screw hole, and a through hole for the guide rod to pass through is provided on the other clamping claw.

[0018] A guide rod between the two clamping jaws can pass through one of the guide rods to provide a guide for the movement of the clamping jaws.

[0019] Furthermore, a rack is fixed on the inner side of the base near the driving motor, and a driving tooth installed on the output shaft of the driving motor is meshed with the rack.

[0020] The driving teeth installed on the driving motor are meshed with the rack, and when the driving motor is working, the mounting plate installed on the base can be driven to move.

[0021] Furthermore, a positioning cylinder is fixed on the mounting plate, and a positioning groove is fixed on the inner side of the base, and the telescopic block of the positioning cylinder can be inserted into the positioning groove.

[0022] When the positioning cylinder is working, the shrink block at its end can be inserted into the positioning groove on the inner side of the base to define the position of the mounting plate, thereby fixing the position of the robot body.

[0023] Through the above scheme, the present invention has at least the following advantages: this bolt processing robot with a mobile chassis provides a linear moving mechanism for the robot body, and the bolt clamping seat at the end of the robot body can clamp the tail of the bolt. The clamped bolt is moved to the rear processing station, and the end of the bolt can be auxiliary processed. The processed bolt is then moved by the robot body to the rear processing station. Mechanized operation improves work efficiency and reduces production costs.

DETAILED DESCRIPTION

[0027] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] See also Figure 1 The base 1 of this bolt processing robot with a mobile chassis can be fixedly spliced ​​by multiple identical modules through bolts and connecting blocks. After splicing, two parallel guide rails 2 are installed on the top of the base 1. The slider under the mounting block 3 cooperates with the guide rail 2. Driven by the driving motor 4, the mounting plate 3 is moved horizontally, which can drive the robot body 5 fixed on the mounting plate 3 to move horizontally. After the robot body 5 moves, it can clamp the bolts at the bolt placement position and then move to the processing station. After the processing is completed, the bolts can also be reset and placed.

[0029] See also Figure 2 The end of the bolt clamping seat 7 is an adapter frame 8. The connecting plates 9 fixed on both sides of the adapter frame 8 are used to install the claw cylinder 10. The claw cylinder 10 can clamp the tail end of the bolt to complete the clamping of the bolt.

[0030] There are multiple guide sleeves 12 below the connecting sleeve 9. The lower end of the guide rod 13 in the guide sleeve 12 is fixed on the cylinder mounting plate 14. The guide rod 13 can move in the guide sleeve 12, so that the relative position of the cylinder mounting plate 14 is movable, which has a buffering effect during processing and avoids damage to the bolts and the robot body 5 caused by hard connections.

[0031] The upper and lower ends of the spring 15 sleeved on the guide sleeve 12 are in contact with the mounting plate 9 and the cylinder mounting plate 14 respectively. The cylinder mounting plate 14 is pushed outward by the elastic force of the spring 15. The spring 15 also plays a buffering role and can better protect the bolt clamping seat 7.

[0032] The tail end of the guide rod 13 passes through the limit plate 16 on the mounting plate 9, and there is a nut at the tail end of the guide rod 13, which serves to limit the maximum movement position of the guide rod 13 and prevent the cylinder mounting plate 14 at the lower end of the guide rod 13 from detaching from the guide sleeve 12.

[0033] The clamping claws 11 correspond to each other in pairs, and the guide rod 17 on one of the clamping claws 11 is fixedly connected. The guide rod 17 can be inserted into the corresponding through hole of the other clamping claw 11 to provide guidance for the movement of the clamping claws 11, thereby avoiding the clamping claws 11 from moving out of position and causing unstable clamping of the bolt tail end.

[0034] See also Figure 3 and Figure 5 A rack 18 is fixed on the inner side of the base 1, and a driving tooth 19 on the output shaft of the driving motor 4 meshes with the rack 18. Driven by the driving motor 4, the position of the mounting plate 3 can be moved, thereby driving the manipulator body 5 on the mounting plate 3 to move.

[0035] See also Figure 4 and Figure 6 A positioning cylinder 20 is also installed on the mounting plate 3. The telescopic block of the positioning cylinder 20 passes through the mounting plate 3. When the mounting plate 3 moves to the locking position, the positioning cylinder 20 is started, and the positioning cylinder 20 drives the telescopic block to move downward. The telescopic block is inserted into the positioning groove 21 in the base 1, thereby completing the position fixation of the mounting plate 3 and preventing the mounting plate 3 from sliding.

[0036] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.

When the absolute position of the object being described changes, the relative positional relationship may change; Secondly: In the drawings of the embodiments disclosed in the present invention, only the structures related to the embodiments disclosed in the present invention are involved, and other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of the present invention can be combined with each other; Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
