Description

Technical Field

[0001] This application relates to the field of lawnmowers, and more particularly to a blade assembly auxiliary device and blade assembly equipment. Background Technology

[0002] In the production and assembly process of lawnmower cutter heads, the precise and efficient installation of the blades and the cutter head is crucial, directly affecting the equipment's performance and operational safety. Traditional assembly methods rely primarily on operators manually placing the cutter head and installing the blades one by one. This method has significant drawbacks: First, the cutter head lacks effective and stable positioning and constraint during assembly, making it prone to radial and circumferential offset or rotation. This results in blades not being accurately installed in their pre-set mounting positions, causing deviations in installation angle and position. Second, the force applied during blade installation can cause axial runout or micro-displacement of the cutter head, further exacerbating the positioning inaccuracy problem. These positioning deviations not only significantly reduce assembly efficiency, forcing operators to make repeated adjustments, but more importantly, they lead to poor dynamic balance performance of the assembled cutter head. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a disc assembly auxiliary device and a cutter disc assembly equipment.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: This application provides: A tool turret assembly auxiliary device, comprising: A plate component, wherein the plate component has a positioning groove and a positioning element is disposed in the positioning groove; A support limiting member is disposed on the plate, and the support limiting member is coaxial with the positioning groove and located in its circumferential direction; A cover is disposed on the support limiting member, and a first positioning hole is provided through the cover. The plate, the support limiting member, and the cover define an accommodating space for accommodating a cutter head. The cutter head has a second positioning hole, and a positioning member is provided for passing through the second positioning hole and the first positioning hole. The cutter head has a cutter mounting position, and a mounting hole corresponding to the cutter mounting position is provided on the cover.

[0024] This application provides a tool disc assembly auxiliary device, including a plate 100, a support and limiting member 200, and a cover 300. Specifically, the plate 100 has a positioning groove 110, in which a positioning member 120 is disposed. The support and limiting member 200 is disposed on the plate 100, and is coaxial with the positioning groove 110 and located in its circumference. The cover 300 is disposed on the support and limiting member 200, and has a first positioning hole 310 passing through it. The plate 100, the support and limiting member 200, and the cover 300 define and form an accommodating space for accommodating a tool disc 400. The tool disc 400 has a second positioning hole 410, and the positioning member 120 passes through the second positioning hole 410 and the first positioning hole 310. The tool disc 400 has a tool mounting position, and the cover 300 has a mounting hole 330 corresponding to the tool mounting position.

[0025] See Figure 1 , Figure 2 as well as Figure 3As shown, when it is necessary to install the blade onto the cutter head 400, first align the positioning member 120 with the second positioning hole 410, and then align the first positioning hole 310 with the positioning member 120. The positioning member 120 passes through the second positioning hole 410 and the first positioning hole 310 in sequence, thereby positioning the cutter head 400 in the radial direction. The cover 300 is pressed down onto the upper surface of the cutter head 400 to prevent the cutter head 400 from moving in the axial direction. At this time, the cutter head 400 is located in the accommodating space, thereby limiting the position of the cutter head 400 and preventing it from moving when the blade is installed onto the cutter head 400. This prevents the blade from being unable to be installed in the preset position due to the movement of the cutter head 400 during installation, which would affect the cutting balance due to installation deviation during subsequent use, and also prevents the blade from falling off.

[0026] There should be at least two positioning elements 120 so that the cutter head 400 can be limited in the radial direction. It is understood that the number and position of the second positioning hole 410 and the first positioning hole 310 should correspond to the number and position of the positioning elements 120 so that each positioning element 120 can be positioned by passing through the corresponding second positioning hole 410 and first positioning hole 310.

[0027] In this embodiment, both plate 100 and cover 300 are plate-shaped, and positioning member 120 is a pin.

[0028] Please continue reading. Figures 1 to 4 As shown, multiple mounting holes 330 are evenly spaced on the cover 300, which allows for uniform installation of the blades. In order to ensure that the blades are smoothly installed on the tool mounting positions of the cutter head 400 according to the preset angle and position, mounting holes 330 are made on the cover 300 that correspond to the number and position of the tool mounting positions. At this time, the blades can be placed in the mounting holes 330 to make the blades correspond to the tool mounting positions. Then, the blades can be fixed on the tool mounting positions by manually or by machine by tightening the bolts, so as to achieve precise installation of the blades.

[0029] The mounting hole 330 extends through the cover 300, and the shape of the mounting hole 330 is adapted to the blade, that is, the shape of the mounting hole 330 can be adaptively adjusted according to different models or specifications of blades.

[0030] In this embodiment, the mounting hole 330 is designed such that when the positioning member 120 passes through the second positioning hole 410 and the first positioning hole 310, the mounting hole 330 corresponds to the tool mounting position. At this time, the tool mounting position is within the area of ​​the mounting hole 330, which facilitates the installation of the cutting tool according to the pre-distributed position. Furthermore, the positioning member 120 is cylindrical. To facilitate the positioning member 120 passing through the second positioning hole 410 and the first positioning hole 310, the top edge of the positioning member 120 can be rounded or chamfered. In practice, it can be designed according to needs. The positioning member 120 can be clearance-fitted with the second positioning hole 410 and the first positioning hole 310 to facilitate the insertion of the positioning member 120.

[0031] In some embodiments, the cross section (axial direction) of the support limiting member 200 is "L" shaped. The support limiting member 200 includes a support portion 210 and a circumferential limiting portion 220. The support portion 210 has a support surface, the circumferential limiting portion 220 is disposed at the circumferential edge of the support surface, and the cover member 300 is disposed on the support surface.

[0032] Please continue reading. Figures 1 to 3 As shown, the stepped surface of the support limiting member 200 with an "L" shaped cross section is the support surface of the support part 210. In order to limit the cutter head 400, the cutter head 400 is located in the space formed around the support part 210. The cover 300 is supported on the support surface of the support part 210. In order to further prevent the cover 300 from moving radially, the cover 300 is limited in the space formed around the circumferential limiting part 220, thereby limiting the cover 300 in the radial direction.

[0033] In this embodiment, both the support portion 210 and the circumferential limiting portion 220 are coaxial with the positioning groove 110, and both the support portion 210 and the circumferential limiting portion 220 are annular. The support portion 210 and the circumferential limiting portion 220 can be integrally formed or connected separately. When they are connected separately, the support portion 210 and the circumferential limiting portion 220 can be connected and fixed with bolts.

[0034] In this embodiment, the support part 210 can be fixedly installed on the plate 100 by using bolts, thereby achieving the combination and fixation of the entire support limiting member 200 and the plate 100.

[0035] In some embodiments, the inner diameter (inner circumferential surface diameter) of the support portion 210 is D1, the inner diameter (inner circumferential surface diameter) of the circumferential limiting portion 220 is D2, and the diameter of the cover 300 is D3, satisfying: D1 < D3 ≤ D2.

[0036] Please see Figure 3As shown, in order for the cover 300 to be confined within the space formed by the support limiting member 200 and to support the cover 300, firstly, in order for the support part 210 to support the cover 300, the inner diameter of the support part 210 should be smaller than the diameter of the cover 300, that is, D1 < D3; in order to achieve circumferential limiting of the cover 300, the diameter of the cover 300 needs to be less than or equal to the inner diameter of the circumferential limiting part 220, that is, D3 ≤ D2.

[0037] In some embodiments, a protrusion 420 is provided at the center of the cutter head 400, and a relief groove 320 is provided on the cover 300, through which the protrusion 420 passes.

[0038] See Figure 2 , Figure 3 as well as Figure 5 As shown, in order to better fit and press down the cover 300 against the cutter head 400, a relief groove 320 that matches the protrusion 420 needs to be opened on the cover 300. This allows the protrusion 420 of the cutter head 400 to be avoided, preventing the protrusion 420 from contacting and supporting the bottom surface of the cover 300, thus ensuring that the cover 300 and the cutter head 400 fit together.

[0039] It is understandable that if the cutter head 400 has any parts that affect the fit between it and the cover 300, a corresponding slot can be made in the cover 300 at the corresponding position to avoid it.

[0040] In some embodiments, at least one groove 130 is provided on the periphery of the positioning groove 110. The inner end face of the groove 130 is an arc surface coaxial with the positioning groove 110. The inner diameter of the support part 210 is D1, the diameter of the arc surface is D4, and the diameter of the positioning groove 110 is D5, satisfying: D1 > D4 > D5.

[0041] Please continue reading. Figures 1 to 4 As shown, when the blade needs to be manually removed from the plate 100 after installation, it can be picked up by holding the edge of the blade disc 400. For easy picking up, the blade disc 400 needs to be partially exposed outside the receiving space. For this purpose, a groove 130 is opened on at least one peripheral side of the plate 100. The groove 130 extends into the receiving space, so that after the blade disc 400 is placed in the receiving space, part of the blade disc 400 will be located in the groove 130. After the blade is installed on the blade disc 400, the blade disc 400 together with the cover 300 can be moved away from the plate 100, so that the positioning member 120 is separated from the second positioning hole 410 and the first positioning hole 310, thus completing the disassembly of the blade disc 400.

[0042] Furthermore, in order to satisfy the requirement that the groove 130 extends into the accommodating space, the diameter of the arc surface of the groove 130 should be smaller than the inner diameter of the support portion 210, that is, D1 > D4. Correspondingly, in order not to affect the placement of the cutter head 400, the groove 130 does not extend into the positioning groove 110, that is, D4 > D5.

[0043] In this embodiment, to facilitate the disassembly and removal of the blade disc 400, grooves 130 are provided on the two opposite sides of the plate 100, specifically as follows: Figures 1 to 4 As shown.

[0044] In some embodiments, the bottom surface of the plate 100 is provided with a plurality of support feet 140, the number of support feet 140 being N, satisfying: N≥3.

[0045] To improve the stability of the plate 100, at least three support feet 140 are provided on the bottom surface of the plate 100 to support it. It can be understood that the three support feet 140 can form a stable triangle to support the support feet 140, thereby preventing the plate 100 from shaking.

[0046] See Figure 4 As shown, in order to further improve the stability of the plate 100, there are four support feet 140, which are respectively located at the four corners of the bottom surface of the plate 100.

[0047] In some embodiments, the cutter head assembly auxiliary device further includes a magnetic suction assembly 500, which is used for the cover 300 to fit against the support surface. The magnetic suction assembly 500 includes a plurality of first magnetic suction members 510 disposed on the support surface and a plurality of second magnetic suction members 520 disposed on the cover 300 and corresponding one-to-one with the first magnetic suction members 510. Specifically, a plurality of first receiving holes 501 are provided on the support surface, and the plurality of first magnetic suction members 510 are respectively disposed in the plurality of first receiving holes 501. A plurality of second receiving holes 502 are provided on the cover 300, which are respectively corresponding to the plurality of first receiving holes 501, and each second magnetic suction member 520 is disposed in the corresponding second receiving hole 502.

[0048] Please see Figures 1 to 3 As shown, in order to improve the downward pressing force of the cover 300 on the cutter head 400, a magnetic attraction method is used to combine the cover 300 with the support part 210. Specifically, a first magnetic attraction member 510 is provided in the first receiving hole 501 on the support part 210, and a second magnetic attraction member 520 is provided in the second receiving hole 502 of the cover 300. It can be understood that the positions of the first magnetic attraction member 510 and the second magnetic attraction member 520 correspond to each other. That is, after the positioning member 120 passes through the first positioning hole 310, each first magnetic attraction member 510 and each second magnetic attraction member 520 correspond one-to-one to achieve magnetic attraction.

[0049] For example, the first magnetic member 510 and the second magnetic member 520 can both be magnets. The magnetic properties of the first magnetic member 510 and the second magnetic member 520 facing each other are opposite, thereby achieving magnetic connection.

[0050] In another embodiment, the first magnetic attractor 510 can be a magnet and the second magnetic attractor 520 can be an iron product, or the first magnetic attractor 510 can be an iron product and the second magnetic attractor 520 can be a magnet. In practice, the selection can be made according to actual needs and is not limited here.

[0051] This embodiment also provides a cutter head assembly device, which includes any of the cutter head assembly auxiliary devices mentioned above. It is understood that the assembly device can use components such as multi-axis robotic arms to automatically load and unload the cutter head 400 and cover 300, place the blades in the mounting holes 330, and then install the blades on the cutter head 400 by screwing in screws, thereby achieving automatic installation and fixing. The components and devices for achieving automatic loading and unloading and for transferring and screwing in the blades are not limited here.
