Description

Technical Field

[0001] The present invention relates to the technical field of electric tools, in particular to the technical field of angle grinder manufacturing, and more particularly to an angle grinder housing, a metal profile assembly component for the angle grinder housing, and a corresponding assembly method. Background Art

[0002] Power tools, such as angle grinders, straight grinders, saber saws, etc., face many challenges during use. These challenges mainly involve the tool's operating comfort, heat dissipation, and overall structural layout. Therefore, it is very necessary to improve the housing or structural parts of power tools to obtain various benefits.

[0003] First, the handle design of traditional power tools often fails to fully consider the operator's need for long-term use. For example, the handles of some angle grinders are thick and difficult to hold, which can easily cause hand fatigue in the operator. By improving the handle design, such as placing the drive control circuit board in the head shell, the handle size can be made thinner and the grip comfort can be improved (refer to patent document authorization announcement number CN 219787830 U).

[0004] Secondly, when the power tool is running at high speed, it will generate a lot of heat. If the heat dissipation is insufficient, it may affect the performance and service life of the tool. Traditional heat dissipation design is often not comprehensive enough to meet the needs of continuous work. By setting up multiple sets of heat dissipation ducts in different parts of the tool, such as between the drive motor and the head shell, in the handle, in the battery box, and in the mounting seat, the heat dissipation effect of the tool can be significantly improved (refer to patent document authorization announcement number CN 220029725 U).

[0005] In addition, the layout of the internal structure of the power tool also directly affects its performance and user experience. For example, the position and angle design of the control panel have an important impact on the overall size and heat dissipation effect of the tool. By placing the control panel at an angle along the extension direction of the main body and located behind the heat dissipation port and the brushless motor, the height of the tool can be reduced and it is easy to grip while ensuring effective cooling of the brushless motor and control panel (reference patent document authorization announcement number CN 219504426 U).

[0006] Therefore, the improvement of the power tool housing or structural parts is a comprehensive project, which requires trade-offs and innovations in multiple aspects such as operating comfort, heat dissipation, structural layout and production process to obtain the best user experience and product performance. These improvements not only include the optimization of the internal structure, but also involve the design of external auxiliary devices, such as grip assist devices, to comprehensively improve the user experience and functionality of power tools.

Rhythm control: The blocking mechanism can effectively control the rhythm of the metal profile unloading, avoiding the problem of material accumulation or insufficient supply, and ensuring the stability of production. Strong adaptability: The design of the feeding mechanism enables the assembly component to adapt to metal profiles of different specifications, enhancing the versatility of the equipment. Good balance: Two sets of symmetrically arranged continuous linear propulsion mechanisms ensure the balance of propulsion force and reduce deviations during assembly.

Good adaptability: It can process edge metal profiles and middle metal profiles at the same time to meet the assembly needs of different parts. Stable beat: By pausing the push and starting the cutting, a stable production beat is achieved to ensure product quality consistency. High material utilization: Precise push and cutting control reduces material waste and improves the utilization rate of raw materials. Adjustable production rhythm: By adjusting the working frequency of the cylinder, the production rhythm can be flexibly adjusted to meet different production needs. Strong traceability: Each step is clearly defined, which is convenient for establishing a production traceability system and is conducive to quality management. Optimized space layout: The design of the push block falling into the receiving bucket optimizes the utilization of the working space and improves the space efficiency of the production line.

[0012] Preferably, the feeding mechanism includes a middle guide groove and a side guide groove, which are used to load different metal profiles respectively. The middle guide groove and the side guide groove enable the feeding mechanism to place metal profiles of different specifications, thereby increasing the application range of the feeding mechanism, providing a larger raw material selection space for subsequent assembly, and enhancing the practicality of the method.

The introduction of the moving device enables the driving device to approach or leave the push block as required, thereby improving the flexibility of the drive.

[0018] As a preference, a blocking mechanism is also included in the feeding mechanism, which can control the output rhythm of the profile, prevent blockage, and improve the reliability of the automated operation.

[0019] Preferably, the feeding mechanism is a structure formed by an annular enclosure, and has a middle guide groove and a side guide groove for placing different metal profiles.

DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the embodiments shown in all the accompanying drawings: Example 1 See attached Figure 5This embodiment discloses an angle grinder equipment housing, including a body housing 01 and a base 31 integrally injection molded with the body housing 01, the base 31 is preferably arranged at the lower side of the body housing 01, and a grip assisting device 20 is installed on the base 31, the grip assisting device 20 functions to bind the angle grinder to the operator's hand, assist the palm to hold the tool body, and share part of the gripping force, thereby significantly reducing the degree of force exerted by the palm and finger muscles, effectively delaying the occurrence of muscle fatigue, and reducing the burden on the hand muscles. The grip assisting device 20 includes: a connecting mechanism that can be detached from the base 31, the connecting mechanism includes an auxiliary belt 02 tied to the back of the hand, a groove rail 03 generally made of metal and mounted in the base 31 for fixing the auxiliary belt 02, two connecting buckle seats 025 that can be slidably installed in the groove rail 03, and a locking buckle 024 for loosely connecting the buckle seats; the auxiliary belt 02 includes two straps 021 and a connecting buckle 022 for movably connecting the two straps. The binding method of the auxiliary belt 02 can be in any form, such as using a press-fit fastener. The embodiment shows that one end of the two straps 021 is respectively buckled on the middle connecting buckle 022, and after being tightened, they are bonded and bound by a universal patch 023, and the other end is locked on the connecting buckle seat of the angle grinder body shell 01 by a locking buckle 024. On the other hand, the auxiliary device can also serve as a strap for storing the tool power cord, making the power cord storage more tidy. Considering the needs of daily use, the grip auxiliary device should be easy to tie on the palm, and can be quickly disassembled and replaced; its tightening degree should be adjustable to accommodate palms of different sizes. Therefore, the metal fixings embedded in the tool body shell 01 can use a metal profile of a certain length, and adjust its relative position to adapt to different palm sizes.

[0029] The structural features of the base 031 are as follows: Material: The base 031 is made of the same engineering plastic material as the body shell 01, such as ABS, and is made through an integrated injection molding process. Shape: The base 031 is in the shape of a slender strip, and its cross section can be an open groove structure similar to the shape of a "T or I or Concave". This design can provide sufficient strength and facilitate the installation of the metal groove rail 03. Length: The base 031 extends along the long axis direction of the body shell 01, and its length is approximately 1 / 3 to 1 / 2 of the length of the body shell 01 to ensure sufficient installation space and support strength. Internal structure: The base 031 is provided with a slot or groove matching the metal groove rail 03 for firmly installing the groove rail 03. Surface treatment: The outer surface of the base 031 may be treated with an anti-slip texture to increase the friction with the auxiliary belt 02.

[0030] Features of the groove rail 03: Material: Wear-resistant, high-strength metal materials such as stainless steel or aluminum alloy are used. Installation method: The groove rail 03 is firmly installed in the base 031 through buckles, screws or embedded designs. Length: The length of the groove rail 03 is equivalent to that of the base 031 to provide sufficient sliding space. Section shape: The section design of the groove rail 03 matches the base 031, which is an "I" shape or a "T" shape or other shapes to facilitate the sliding and fixing of the buckle seat 025.

[0031] These improvements can not only improve the comfort and performance of the tool, but also extend the tool life and improve work efficiency. However, when implementing these improvements, the adaptability of the production process and assembly process must also be considered. Adding or changing the structural design may require the existing automated production assembly line to be updated and modified accordingly to meet the new process requirements.

[0032] With respect to the above-mentioned angle grinder equipment housing, this embodiment provides a metal profile continuous linear assembly component for realizing automatic assembly between the angle grinder equipment housing and the metal profile.

[0033] The main object of the assembly is the housing body shell 01 of the angle grinder device, and one or more metal profiles of different sizes assembled therewith. These metal profiles can form two or more groove rails for guiding through a specific combination.

[0034] The housing body 01 of the angle grinder device has a matching guide groove or a fixing structure for fitting the metal profile, that is, the structure of the aforementioned base 031 .

[0035] The automatic assembly component can realize the continuous linear assembly of the metal profile and the fuselage shell 01, and complete the insertion and fixation of the profile. The profile and the details after assembly can be referred to the attached Figure 3-Figure 5 .

[0036] In this embodiment, the guide groove tracks on the shell are designed to be two, and the corresponding metal profiles installed include: a middle metal profile 002 located in the middle, and side metal profiles 001 located on both sides of the middle profile (two in total).

[0037] Considering that the raw materials of metal profiles usually adopt standard lengths, such as 1000mm, and their cross-sectional dimensions are relatively small, the profiles are more likely to bend and deform. Therefore, when designing the package technical solution, it is necessary to pay attention to the guide rail structure of the guide profile to facilitate the continuous replenishment of new raw materials and to limit the bending of the profile during the push straight stroke.

[0038] In order to prevent the profile from bending and deforming during the pushing process, the specific design of this embodiment is: The entrance material receiving section of the guide rail has a large opening to facilitate the introduction of new metal profile raw materials; the extension section after the material receiving section is a slidable pushing section that tightly covers the profile, which can effectively prevent the profile from bending during the straight pushing stroke.

[0039] The assembly components mainly include: The feeding mechanism 100 located at the top has the function of sequentially introducing the metal profile raw materials into the assembly process. The feeding mechanism 100 is enclosed by multiple groups of annular enclosures to form a funnel-shaped structure with a large top and a small bottom, including a middle guide groove 110 and side guide grooves 120 on both sides. The side guide grooves are tilted outward at a certain angle to facilitate the introduction of metal profile raw materials.

[0040] The assembly guide rail 003 is located directly below the feeding mechanism. The guide rail has a guide groove that matches the profile and is used to accurately guide the assembly movement of the metal profile.

[0041] The blocking mechanism 004 disposed in the feeding mechanism 100 controls the rhythm of the metal profile feeding to prevent the profile from accumulating and causing it to get stuck or deform. The blocking mechanism can also be a simple structure in which a cylinder is used as an independent power and the telescopic end of the cylinder is used as a blocking.

[0042] The two sets of continuous linear propulsion mechanisms 005 symmetrically arranged on both sides of the feeding mechanism 100 have the function of continuously and uninterruptedly pushing and inserting the metal profile into the housing of the power tool to complete the assembly.

[0043] The blocking mechanism 004 includes: an eccentric blocking sleeve 041 arranged at the bottom of the outer side of the edge guide groove 120, and torsion springs are arranged at both ends of the eccentric blocking sleeve 041. The torsion springs are assembled by setting a mounting pin 042, and the mounting pin 042 is fixedly connected to the discharge hopper 101. The cross section of the eccentric blocking sleeve 041 is an eccentric circle dragging a small rocker arm. When the small rocker arm is moved, the eccentric circle can rotate around the axis of the mounting pin 042. When the eccentric circle rotates into the lower end outlet of the edge guide groove 120, it plays a blocking role and regulates the stopping and moving of the passing profile. Through the rotational movement of the eccentric blocking sleeve, the structure can flexibly control the intermittent output of the profile to avoid deformation of the profile after a large amount of accumulation.

[0044] The assembly guide rail 003 includes a front starting section 031, a middle section 032, and a rear section 033; the overall assembly guide rail 003 is spliced ​​and fixed by the starting section 031, the connecting section 032, and the connecting section 033. Each section has a different function, and the cross-section of the rail shape also changes. The starting section 031 is cantilevered on the outer edge of the feed hopper and is mainly used to bear the work of the push block 052 entering the rail. The connecting section 032 is used to accurately receive and guide the profile to enter the rail. The connecting section 033 is used to guide the docking of the profile with the outer shell body shell 01 and plays a stabilizing role in the assembly process. The supporting function is that the up and down movement of the profile pushed to this section is strictly controlled, and it can only move along the track toward the outer shell body shell 01. The profile is relatively long, and each profile needs to be cut and segmented at a certain distance after being inserted into the outer shell body shell 01. During cutting, the profiles on both sides of the cutting blade are still in the track and are controlled to move up and down by the track. For this reason, the set section 033 is provided with a process notch 331 just below the cutting blade to avoid the cutting tool, and a receiving bucket 006 is provided below the process notch 331 to receive the push block 052 and cutting chips that have completed the pushing operation.

[0045] The continuous linear propulsion mechanism 005 includes a push block conveyor frame 051 and a push block 052. The push block conveyor frame 051 is installed on the starting push side and includes a stacked upper and lower guard rod seats 053 and guard rods 054. The guard rods 054 are inserted in pairs on both sides of the guard rod seats 053 to form a square channel for sequential stacking and downward movement of the push blocks 052. The push blocks 052 are movably placed in the channel, and have teeth on both sides to mesh with the long toothed belt for transmission.

[0046] The continuous linear propulsion mechanism 005 also includes a moving device 055 and a driving device 056 fixed on the moving device 055 and moving forward and backward together with the moving device 055.

[0047] The moving device 055 includes a translation plate 551, a slide rail assembly arranged under the translation plate 551, and a cylinder 552 arranged on the outside of the translation plate 551; when the output shaft of the cylinder 552 is extended, it pushes the translation plate 551 to move and lean against the upward feeding mechanism 100 to achieve linear propulsion of the entire mechanism.

[0048] The driving device 056 includes a long toothed belt 561, a toothed belt frame plate 562 for supporting the long toothed belt 561, a push rod assembly 563 located on the side of the push block for limiting the free fall of the push block, and a power source 564; the toothed belt frame plate 562 is fixed to the lower end surface of the translation plate 551 on the side facing the upper feeding mechanism 100, and a groove is arranged around the toothed belt frame plate 562. The long toothed belt 561 can be movably wrapped in the groove around the toothed belt frame plate 562, and the groove acts as a guide track to ensure the smooth movement of the long toothed belt.

[0049] A plurality of levers 008 are arranged on the toothed belt frame plate 562, and each lever 008 is fixed to the upper end surface of the toothed belt frame plate 562 close to the eccentric resistance sleeve 041. When the continuous linear propulsion mechanism 005 moves as a whole toward the feeding mechanism 100, the lever 008 pushes the eccentric resistance sleeve 041 to rotate, thereby realizing intermittent output of the profile.

[0050] The push rod assembly 563 has elastic and telescopic functions, and is composed of a push rod, a compression spring, and a push rod seat to achieve control of the push block conveying.

[0051] The push rod assembly 563 is fixed on the side of the toothed belt frame plate 562 close to the push block conveyor frame 051. The long toothed belt 561 is closely engaged with the push block 052 on the push block conveyor frame 051 to transmit power. The long toothed belt 561 is driven by the power source 564. The function of the push rod assembly 563 is to resist the push block 052 and prevent it from moving downward.

[0052] The power source 564 includes a gear shaft rotatably fixed on the translation plate 551 and a power motor connected to the gear shaft. The gear shaft meshes with the long toothed belt 561 for transmission. The long toothed belt 561 meshes with the push block 052 after contacting, thereby forming a toothed belt transmission group, which drives the push block 052 to push the profile to the assembly work surface along the assembly guide rail 003.

[0053] Refer to all attached Figure 1-Figure 11 , the working process of embodiment 1 is as follows: 1. Place the edge metal profile 001 and the middle metal profile 002 into the guide grooves respectively, and enter the corresponding material receiving section 032 under the action of gravity. Push block 052 enters the starting section 031.

[0054] 2. The cylinder 552 starts, driving the entire mechanism to move toward the assembly guide rail 003. The push block 052 meshes with the long toothed belt 561, and the lever 008 drives the eccentric resistance sleeve 041 to rotate, so that the thick wall part is rotated out and prevents the new material from entering, thus achieving orderly feeding. The push rod assembly 563 also prevents the new push block from moving down, ensuring the smooth operation of the push block that has entered the track.

[0055] 3. The long toothed belt 561 drives the push block 052 to push the profile from the material receiving section 032 to the set section 033. The profile is strictly controlled in the set section 033. After entering the shell for a certain distance, the light control system stops pushing and the external cutting machine starts cutting the profile. After the light control is restored, pushing continues until the profile is taken.

[0056] 4. Push block 052 is pushed out of the guide rail and falls into the receiving bucket 006. Cylinder 552 works in the reverse direction and all components are reset. The profile and push block enter the large cycle again and run repeatedly until the processing is completed.

[0057] The main contents of the metal profile automatic set method: 1. Feeding mechanism: - Set up middle guide grooves and side guide grooves to load different metal profiles respectively.

[0058] - The top of the feeding mechanism is a funnel structure, which uses gravity to guide the profiles in.

[0063] - The gear shaft and long toothed belt drive the push block to push the profile.

[0064] - Set the push rod and push rod to realize the orderly transportation of push blocks and profiles.

[0065] 4. Working process: - The profile enters the rail through the guide groove, and the push block starts to push the profile into the set section.

[0066] - After pushing to a certain distance, pause and cut externally; then push the profile mother section to complete the assembly.
