Description

Technical Field

[0001] The utility model belongs to the technical field of application components of grinding machines, and particularly relates to an electrode cap storage and supply device. Background Technique

[0002] At present, the storage and supply units of electrode caps for automatic cap changers in the industry are roughly divided into two categories, namely spring-powered push type and gravity type. The spring type can be further subdivided into in-line spring type and coil spring type. The functional principle of this type is to use the force of spring compression and rebound to push the stored electrode caps outwards, so that after the electrode gripper replaces a new electrode cap, the remaining electrode caps can be automatically replenished. Its specific structures include in-line type and disc type, etc. The other type is to achieve automatic replenishment of the stored electrode caps by the principle of self-weight falling. However, the installation attitude of this type of device is restricted and can only be installed and arranged in the direction of gravity.

[0003] The existing electrode cap storage and supply devices have the following deficiencies:

[0004] 1. There is a defect that the pushing force is uneven due to the spring thrust. The spring compression deformation at the end position is small and the thrust decreases;

[0005] 2. The installation attitude of the device relying on gravity as the driving force is restricted and cannot meet the space requirements of many factory workstations;

[0006] 3. The reliability is relatively low, and the service life is restricted by the spring performance. Content of the Utility Model

[0007] The purpose of the utility model is to provide an electrode cap storage and supply device to solve the technical problems raised in the background technique.

[0008] To achieve the above purpose, the specific technical solution of the utility model is as follows: An electrode cap storage and supply device includes a storage housing and a cover plate fixedly connected to the upper surface of the storage housing. Storage grooves are arranged on both sides of the upper surface of the storage housing along its length direction. An installation groove parallel to the storage groove is arranged on one side of the storage groove. A linear guide rail is installed on the installation groove. A slider is slidably connected to the linear guide rail. A push rod is fixedly connected to one side of the slider. A driving mechanism for driving the slider to move is installed in the inner cavity at one end of the storage housing. And two limiting devices are arranged on one side of the driving mechanism in the inner cavity of the storage housing. A proximity switch is installed on each of the front and rear side walls of the storage housing near the driving mechanism. A base quick-insert plate device detachably connected to the storage housing is arranged at the bottom of the storage housing;

[0009] The driving mechanism includes a connecting shaft which is rotatably connected to the storage housing through bearings. Both ends of the connecting shaft are sleeved with winding wheels around which winding springs are wound. The end of the winding spring is fixedly connected to the slider.

[0010] Preferably, the cover plate is fixedly connected to the storage housing by screws, and two observation windows parallel to the storage groove are arranged on the upper surface of the cover plate.

[0011] Preferably, the limiting device includes a limiting housing. Installation cavities are arranged at one end of each of the two limiting housings away from each other. A spring post is installed in the installation cavity. The end of the spring post is connected to a ratchet pawl. The end of the ratchet pawl extends outside the installation cavity, and the upper surface of the ratchet pawl is rotatably connected to the limiting housing through a rotating shaft.

[0012] Preferably, the ratchet pawl is located above one side of the storage groove.

[0029] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail an electrode cap storage and supply device of the present utility model with reference to the accompanying drawings.

[0030] As Figures 1-6 shown, an electrode cap storage and supply device of the present utility model includes a storage housing 7 and a cover plate 1 fixedly connected to the upper surface of the storage housing 7. Storage grooves 9 are provided on both sides of the upper surface of the storage housing 7 along its length direction. The storage grooves 9 are used for placing electrode caps. The cover plate 1 and the storage housing 7 are fixedly connected by screws, and two observation windows 8 parallel to the storage grooves 9 are provided on the upper surface of the cover plate 1. The cover plate 1 is used for the installation and fixation of the top surface of the device. At the same time, the cover plate 1 is provided with a cover plate with high hardness for clamping and supporting the electrode caps. The setting of the observation windows 8 can observe the change in the number of electrode caps in the storage grooves 9. The bottom of the storage housing 7 is also provided with a cover plate with high hardness for clamping and supporting the electrode caps.

[0031] On one side of the storage slot 9, there is an installation slot 10 distributed in parallel with it. A linear guide rail 11 is installed on the installation slot 10. A slider 14 is slidably connected to the linear guide rail 11. One side of the slider 14 is fixedly connected to a push rod 2. Inside one end of the storage housing 7, a driving mechanism for driving the slider 14 to move is installed. The driving mechanism includes a connecting shaft 12. The connecting shaft 12 is rotatably connected to the storage housing 7 through a bearing. Both ends of the connecting shaft 12 are sleeved with winding wheels 13. A winding spring 3 is wound around the winding wheels 13. The end of the winding spring 3 is fixedly connected to the slider 14. The winding spring 3 drives the slider 14 to perform a linear motion on the bearing surface of the linear guide rail 11, so that the push rod 2 moves along with the movement of the slider 14, so that the electrode cap can move along with the movement of the push rod 2, thereby generating a top pushing force acting on the electrode cap.

[0032] On one side of the driving mechanism inside the storage housing 7, there are two limiting devices 5. On the front and rear side walls of the storage housing 7 near the driving mechanism, a proximity switch 4 is installed. The limiting device 5 includes a limiting housing 15. At one end of the two limiting housings 15 away from each other, there is an installation cavity 16. A spring column 18 is installed in the installation cavity 16. The end of the spring column 18 is connected to a pawl 17. The end of the pawl 17 extends to the outside of the installation cavity 16. The upper surface of the pawl 17 is rotatably connected to the limiting housing 15 through a rotating shaft. The pawl 17 is located on the upper side of the storage slot 9. When the electrode cap is moved to the limiting device 5, the pawl 17 will contact the electrode cap, thereby blocking the electrode cap.

[0033] At the bottom of the storage housing 7, there is a base quick-insert plate device 6 detachably connected to it. The base quick-insert plate device 6 includes a support 19. In the middle part of the upper surface of the support 19, there are two symmetrically distributed cylindrical pins 20. At the bottom of the storage housing 7, there are two positioning holes corresponding to the cylindrical pins 20. The support 19 and the bottom of the storage housing 7 are fixedly connected by bolts 21. When performing the quick replacement action, by rotating the bolts 21, the equipment is adjusted to the cap replacement action. At this time, the storage housing 7 can be quickly moved, and the electrode cap can be filled externally. After the filling is completed, the quick alignment can be carried out through the cylindrical pins 20, and the bolts 21 can be screwed to adjust the equipment to the closed state.

[0034] The working principle of this electrode cap storage and supply device: When the electrode caps are loaded into the storage housing 7 and reach full load, the storage housing 7 and the base quick-insert plate device 6 are installed and fixed on the base. The electrode caps move outwards through the push rod 2. The outermost electrode cap is stuck at the pawl 17 of the limiting device 5. The robot moves over with the welding torch to replace the outermost electrode cap, leaving a vacancy for one electrode cap at the end position. At the same time, the push rod 2 pushes all the electrode caps to move as a whole to fill the vacancy and wait for the next cap replacement.

[0035] It can be understood that the present utility model is described by means of some embodiments. Those skilled in the art will be aware that, without departing from the spirit and scope of the present utility model, various changes or equivalent substitutions can be made to these features and embodiments. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present utility model.
