Description

Technical Field

[0003] The reciprocating saws currently on the market usually use a transmission mechanism to convert the torque of the motor into the linear reciprocating motion of the saw blade to achieve cutting. In actual application, when sawing different materials, different sawing frequencies are required, and the existing reciprocating saws generally have an operating frequency that is synchronized with the motor, and cannot reduce the sawing frequency.

During use, the battery pack is exposed to a complex working environment and is also more susceptible to damage. Utility Model Content

Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present disclosure; the directional words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0046] At present, the existing reciprocating saws use a transmission mechanism to convert the torque of the motor into the linear reciprocating motion of the saw blade during the reciprocating motion of the saw blade, thereby achieving cutting. In actual application, when sawing different materials, different sawing frequencies are required, and the existing reciprocating saws generally have an operating frequency that is synchronized with the motor, and cannot reduce the sawing frequency.

[0047] In order to alleviate the above problems, an embodiment of the present disclosure provides a reciprocating saw that can use a planetary reduction gear set to adjust the rotation speed of the motor to an operating frequency suitable for sawing by the saw blade through a reduction ratio.

[0048] Reference Figure 1 and Figure 2 The embodiment of the present disclosure provides a reciprocating saw 001, comprising: a reciprocating rod 10, a motor 20, a transmission member 30 and a support structure 60; wherein the proximal end of the reciprocating rod 10 is used to connect the saw blade, and the reciprocating rod 10 has a linkage cavity 11; the motor 20 comprises a motor shaft 21; the transmission member 30 comprises a planetary reduction gear set 32 ​​synchronously driven with the motor shaft 21, a gear steering transmission set 31 synchronously driven with the planetary reduction gear set 32, and an eccentric wheel 33 synchronously driven with the gear steering transmission set 31; the transmission member 30 also comprises a guide piece 34, a guide piece 34 for providing a guide piece 34 with a guide piece 34; The guide block 35 of the guide channel and the rolling bearing element 36 accommodated in the linkage chamber 11, the guide plate 34 is located between the eccentric wheel 33 and the gear steering transmission group 31, through the linkage chamber 11 and the rolling bearing element 36, the reciprocating rod 10 follows the rotation of the eccentric wheel 33 and reciprocates along its own length direction; the output speed of the planetary reduction gear group 32 is lower than the output speed of the motor 20, that is, the motor 20 adjusts the reciprocating movement frequency of the reciprocating rod 10 through the planetary reduction gear group 32; the reciprocating rod 10, the motor 20 and the transmission component 30 are all assembled and fixed by the support structure 60.

[0049] The rolling bearing element 36 can be implemented as a needle bearing, a ball bearing, a tapered roller, a spherical roller bearing and a sleeve. In this embodiment, the rolling bearing element 36 can be implemented as a needle bearing. Compared with the prior art, the embodiment of the present disclosure adopts both a planetary reduction gear set 32 ​​and a gear steering transmission set 31, which can adjust the rotation speed of the motor shaft 21 of the motor 20 according to the reduction ratio of the planetary reduction gear set 32, and then reduce the rotation speed of the motor shaft 21, and then synchronously transmit it to the eccentric wheel 33 and the reciprocating rod 10 through the gear steering transmission set 31, thereby reducing the working frequency of the reciprocating rod 10 driving the saw blade to move back and forth.

[0050] The reciprocating saw 001 provided in the embodiment of the present disclosure includes but is not limited to applications in the field of electric tools, and may also be applied to other installation scenarios suitable for sawing processing.

[0051] The knife lifting component 50 of the embodiment of the present disclosure may be a separate structural component, or the knife lifting component 50 of the embodiment of the present disclosure may also be a combined structural component of multiple structures.

[0052] In some embodiments, reference Figure 2 , Figure 3 and Figure 4The planetary reduction gear set 32 ​​includes: an internal gear 321, a plurality of planetary gears 322 respectively meshing with the internal teeth of the internal gear 321, a sun gear 323 meshing with the external teeth of each planetary gear 322, and a planetary carrier 324 for fixing and transmitting; the sun gear 323 is synchronously transmitted with the motor shaft 21. Exemplarily, three planetary gears 322 are provided. In the embodiment of the present disclosure, the sun gear 323, the planetary carrier 324 and the internal gear 321 are all concentric, that is, they rotate around a common axis.

[0053] In this way, the intermediate shaft and intermediate gear used in manual transmission can be eliminated. All the gears of the planetary reduction gear set 32 ​​are always meshed with each other, and there is no need to slide the gears when shifting gears, so the friction and wear are small and the service life is long. The structure is simple and compact, and the load is distributed to a large number of teeth, so the strength is high. In addition, the planetary reduction gear set 32 ​​of the embodiment of the present disclosure can obtain multiple transmission ratios, thereby matching the needs of different application scenarios.

[0054] In some embodiments, further reference is made to Figure 2 and Figure 3 The gear steering transmission group 31 includes a first bevel gear 311 and a second bevel gear 312 that mesh with each other, the first bevel gear 311 is synchronously transmitted with the planet carrier 324, and the second bevel gear 312 is synchronously transmitted with the eccentric wheel 33. In this way, the horizontal transmission of the motor 20 can be converted into the vertical transmission of the eccentric wheel 33.

[0055] In some embodiments, further reference is made to Figure 2 The reciprocating rod 10 is also provided with a connecting block 40, and a pulley structure 41 is provided at the bottom of the connecting block 40; the reciprocating saw 001 also includes a knife lifting component 50, which can drive the distal end of the connecting block 40 to move in a direction away from the guide piece 34; the supporting structure 60 has a knife lifting fulcrum, and the reciprocating rod 10 is rotatably connected to the knife lifting fulcrum. In this way, the knife lifting component 50 can drive the distal end of the connecting block 40 to move in a direction away from the guide piece 34, and the reciprocating rod 10 is rotatably connected to the knife lifting fulcrum, so that when the distal end of the knife lifting component 50 moves to a position away from the guide piece 34, the saw blade connected to the proximal end of the knife lifting component 50 can adjust the angle downward, and when the saw blade in the reciprocating saw 001 reciprocates to perform sawing action, the connecting block 40 will not contact the guide piece 34, so that the connecting block 40 will not shake in the longitudinal direction during the reciprocating motion, thereby ensuring that the saw blade will not produce shaking sawing action under certain circumstances.

[0056] The knife lifting component 50 of the embodiment of the present disclosure can drive the distal end of the connecting block 40 to move in a direction away from the guide piece 34. It can be understood that the knife lifting component 50 has the function of lifting or supporting the distal end of the connecting block 40 in a direction away from the guide piece 34. Specifically, the embodiment of the present disclosure takes the function of the knife lifting component 50 in supporting the distal end of the connecting block 40 in a direction away from the guide piece 34 as an example to further elaborate on this scheme.

[0057] In some embodiments, reference Figure 2 , Figure 5 and Figure 6 The knife lifting component 50 is constructed as a knife lifting knob. The knife lifting component 50 includes a main body 52 and a hand-held portion 51 connected to the upper part of the main body 52. ​​The main body 52 has a knife lifting surface 521. The distal end of the connecting block 40 has a lap portion 42. The lap portion 42 can elastically press against the knife lifting surface 521 in the longitudinal direction. The knife lifting component 50 adjusts the position of the distal end of the connecting block 40 in the longitudinal direction through the knife lifting surface 521. In this way, the knife lifting knob can move the distal end of the connecting block 40 away from the guide piece 34 during the screwing process. The hand-held portion 51 is exposed to the external space of the reciprocating saw 001 so that the user can lift the knife rotatably. Furthermore, the knife lifting component 50 is partially exposed to the external space of the reciprocating saw 001. In other words, the knife lifting component 50 is partially exposed to the external space of the casing (that is, the support structure 60) of the reciprocating saw 001.

[0058] Exemplarily, the overlapping portion 42 is configured as a protruding structure protruding from the distal end surface of the connecting block 40 .

[0059] In some embodiments, further reference is made to Figure 5 The knife lifting surface 521 is constructed as a spiral plane on the main body 52, and the spiral plane includes a first height support position 5211 and a second height support position 5212. The first height support position 5211 and the second height support position 5212 are respectively maintained in a staggered arrangement in the height extension direction of the knife lifting member 50, and the first height support position 5211 and the second height support position 5212 are extendedly connected by the spiral surface;

[0060] When the overlap portion 42 is elastically pressed against the first height support position 5211, the bottom pulley structure 41 of the connection block 40 can slide back and forth on the top surface of at least a part of the guide piece 34;

[0061] When the overlapping portion 42 is elastically pressed against the second height supporting position 5212 , the bottom pulley structure 41 of the connecting block 40 can be separated from the guide piece 34 .

[0062] Thus, in the initial state, the overlap portion 42 is elastically pressed between the support structure 60 and the first height support position 5211. At this time, the pulley structure 41 at the bottom of the connection block 40 can slide with at least part of the structure of the guide piece 34, and the pulley structure 41 can reciprocate along the inclined surface at the rear end of the guide piece 34, which will cause the connection block 40 and the saw blade to shake in the longitudinal direction. When the blade lifting member 50 is screwed, the overlap portion 42 is elastically pressed between the support structure 60 and the second height support position 5212. At this time, the pulley structure 41 at the bottom of the connection block 40 can completely separate from the guide piece 34, and there is no sliding fit relationship between the two, so the connection block 40 and the saw blade will not shake in the longitudinal direction.

[0063] In some embodiments, the reciprocating saw 001 further includes an elastic member (not shown in the figure), which is always in a compressed state between the support structure 60 and the connecting block 40 to fix the blade lifting knob therebetween. In this way, the blade lifting knob can be firmly clamped between the support structure 60 and the connecting block 40.

[0064] In some embodiments, the tail end of the guide piece 34 has an inclined surface for the reciprocating movement of the pulley structure 41; the guide block 35 has a guide hole, and the guide piece 34 can be arranged along the guide hole. In this way, the guide block 35 has a guiding effect on the guide piece 34.

[0065] In some embodiments, further reference is made to Figure 1 and Figure 2 The reciprocating saw 001 further includes a bracket 70 and a fan 80, wherein the bracket 70 is used to protect the outer periphery of the saw blade, and the fan 80 is disposed between the motor 20 and the transmission member 30. In this way, the bracket 70 can be used to protect the outer periphery of the saw blade, and the fan 80 can perform real-time heat dissipation treatment on the motor 20 and the transmission member 30.

[0066] In some embodiments, the support structure 60 includes a first shell 61 and a second shell 62, and the first shell 61 and the second shell 62 are detachably connected. In this way, it is easy to install and disassemble the support structure 60, and further facilitate the replacement and maintenance of various internal structural components. Exemplarily, the first shell 61 and the second shell 62 are detachably connected left and right.

[0067] It is worth mentioning that stud slots are reserved in the first shell 61 and the second shell 62, and the first shell 61 and the second shell 62 are connected together by studs. At least 4 stud slots are arranged around the battery compartment to enhance the strength of the battery compartment.

[0069] Specifically, the battery pack is released with one click, wherein the battery mounting portion 64 includes a battery compartment 641, a release mechanism 642 and a pop-up mechanism 643. When the battery pack is locked by the release mechanism 642, the pop-up mechanism 643 is elastically compressed by the battery pack. When the release mechanism 642 is triggered, the pop-up mechanism 643 is unlocked by the release mechanism 642 and then recovers its deformation to cause the battery pack to pop out. In addition, the battery pack is locked by insertion, wherein the housing further includes a battery mounting portion 64, the battery mounting portion 64 and the housing body are arranged at both ends of the grip portion 63, the battery mounting portion 64 includes a battery compartment 641 and at least one locking mechanism 644, wherein the locking mechanism 644 is disposed on the side wall of the battery compartment 641, the locking mechanism 644 includes at least one release trigger 6441 and at least one locking assembly 6442, the release trigger 6441 is exposed to the grip channel 90 defined by the grip portion 63, the locking assembly 6442 includes a transmission element and a locking protrusion, the transmission element is transmission-connected to the release trigger 6441, and the locking protrusion can protrude from the side wall of the battery compartment 641 to the battery cavity defined by the battery compartment 641. Wherein, the battery pack is partially exposed to the opening of the battery compartment 641; and / or when the battery pack is placed in the battery compartment 641, the rear end face of the battery pack does not exceed the extension direction of the rear end face of the grip portion 63.
