Abstract
Description
Technical Field
[0001] This utility model belongs to the field of grinding equipment, specifically relating to a quick-change device for robot grinding and deburring. Background Technology
[0002] The significance of a spindle quick-change device lies in the spindle's ability to automatically change tool holders. By installing different tools and consumables on different tool holders, process switching between different tools / consumables can be achieved. In the machine tool industry, spindles with quick-change devices are already quite mature. Their quick-change structure is integrated inside the spindle (achieved through spindle pulleys, pull studs, and tool holders), forming a highly integrated and stable solution.
[0003] In robotic grinding and deburring applications, most manufacturers currently opt for electric spindles (with integrated quick-change mechanisms) from the machine tool industry for tool / consumable replacement. This leads to the following problems:
[0004] 1. Spindles are used in machine tools and are often quite heavy, placing high demands on the robot's load and performance.
[0005] 2. For grinding and deburring applications, the machining precision in the machine tool industry is too high, which requires high precision of the electric spindle. As a result, the overall design and manufacturing costs increase. This "precision" seems a bit excessive in the grinding and deburring industry, resulting in cost waste.
[0006] 3. The quick-change device is integrated inside the spindle and cannot be removed or replaced independently, resulting in poor flexibility and high maintenance costs. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0034] Example:
[0035] like Figure 1-4 As shown, this embodiment provides a quick-change device for robot grinding and deburring, including a connecting component, a first elastic element 1, a limiting block 2, a sliding sleeve 3, a first partition 4, a second partition 5, a plunger 6, and a tool handle assembly 7.
[0036] The connecting component is provided with a first mounting groove 8 and a second mounting groove 9. The first mounting groove 8 and the second mounting groove 9 are connected. One end of the first elastic member 1, the limiting block 2, and the tool holder assembly 7 are slidably engaged with the first mounting groove 8. The limiting block 2 is located between the first elastic member 1 and one end of the tool holder assembly 7. The first partition 4 is provided in the first mounting groove 8. The limiting block 2 is provided with a limiting part 14 that can abut against the first partition 4.
[0037] One end of the tool holder assembly 7 is provided with a first mating groove 10;
[0038] The plunger 6 is located in the second mounting groove 9, the sliding sleeve 3 is sleeved on the connecting assembly and corresponds to the position of the second mounting groove 9, one end of the plunger 6 is provided with a plug body 11, the plug body 11 is slidably engaged with the plunger 6, a second elastic member is provided between the plug body 11 and the plunger 6, the plug body is located in the first mounting groove 8 and can engage with the first mating groove 10.
[0039] The second partition 5 is located on the tool holder assembly 7 and below the sliding sleeve 3.
[0040] The quick-change device for robot grinding and deburring in this embodiment can quickly perform tool loading and unloading operations. The specific principle is as follows:
[0041] During the tool loading operation: as one end of the tool holder is inserted into the first mounting groove 8, the other end of the tool holder pushes open the plug body 11 at the plunger 6, so that the second elastic element is in a compressed state. At the same time, it pushes the limit block 2 to move upward, so that the first elastic element 1 is in a compressed state, until the plug body 11 is stuck in the first mating groove 10 on the tool holder assembly 7, thus realizing the tool loading.
[0042] During the unloading operation: as one end of the tool holder separates from the first mounting groove 8, one end of the tool holder pushes open the plug body 11 at the plunger 6, and at the same time, the limiting block 2 assists in pushing out the tool holder assembly 7 under the action of the first elastic member 1, thereby realizing the unloading of the tool.
[0043] The sliding sleeve 3 is fitted onto the connecting assembly and corresponds to the position of the second mounting groove 9. It can limit the position of the plunger 6 to ensure the stability of the plunger 6 position during tool loading or tool loading operations.
[0044] In this embodiment, the first mounting slot 8 and the second mounting slot 9 are positioned on the connecting component as follows:
[0045] The first mounting groove 8 is provided along the axial direction of the connecting assembly, and the number of the second mounting grooves 9 is two or more and they are evenly distributed along the radial direction of the first mounting groove 8.
[0046] The mating structure between the plunger 6 and the tool holder assembly 7 in this embodiment is as follows:
[0047] The first mating groove 10 has a semi-circular groove structure in cross-section, and the plug 11 has a spherical structure. The above structure can ensure that the plug 11 can smoothly enter or exit the first mating groove 10, which facilitates tool loading and unloading operations.
[0048] In this embodiment, the first partition 4 and the second partition 5 are ring structures.
[0049] Meanwhile, the first mounting groove 8 is provided with a first annular groove 12 that cooperates with the first partition 4, and the tool holder assembly 7 is provided with a second annular groove 13 that cooperates with the second partition 5.
[0050] Specifically, the first partition 4 is sleeved on the limiting block 2, and the limiting part 14 is located on the top of the limiting block 2. The limiting part 14 is an annular boss structure.
[0051] In the above structure, the first partition 4 and the second partition 5 limit the positions of the limiting block 2 and the sliding sleeve 3, respectively.
[0052] The connecting component in this embodiment is provided with a limiting groove 19, which is located above the sliding sleeve 3. The limiting groove 19 and the second partition 5 further limit the position of the sliding sleeve 3.
[0053] In this embodiment, for the form of external thread on the spindle / motor shaft end, the connecting assembly adopts the first structure: including a spring collet 16 and a connecting body 17, the spring collet 16 is connected to the connecting body 17, and the first mounting groove 8 and the second mounting groove 9 are provided on the connecting body.
[0054] Alternatively, in this embodiment, for the form of the inner hole at the end of the spindle / motor shaft, the connecting component adopts the first structure: optical shaft 18.
[0055] Specifically, the tool holder assembly 7 is provided with a V-shaped slot 15. The function of the V-shaped slot 15 is to cooperate with the tool holder for locking. The robot moves the tool holder assembly 7 through the tool holder to realize the tool loading or unloading operation.
[0056] In summary, the quick-change device for robot grinding and deburring in this embodiment has a reasonable structural design and low cost. The installation method of its connecting components can be adapted according to the form of the spindle / motor shaft end, and it can quickly perform tool loading or unloading operations when used with a robot.
[0057] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
