Description

Technical Field

[0001] This utility model relates to the field of power tool technology, and more specifically, to a wood milling machine. Background Technology

[0002] A power milling machine is a type of power tool used for grooving wood products. During use, the base of the power milling machine contacts the surface of the wood product; the grooving depth can be adjusted by sliding the position of the machine housing relative to the base.

[0003] Currently, some bakelite milling machines achieve a sliding connection between the housing and the base using a guide sleeve and guide post. When sawdust generated during grooving adheres to the guide post or the guide sleeve lacks lubrication, the guide sleeve will have difficulty sliding smoothly relative to the guide post, making it difficult to adjust the position of the housing relative to the base.

[0004] Therefore, it is determined that it is necessary to provide an improved bakelite milling machine to overcome the shortcomings of the existing technology. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wood milling machine that facilitates the adjustment of the position of the machine housing relative to the base.

[0006] The present invention solves the existing technical problems by adopting the following technical solution: A bakelite milling machine, the bakelite milling machine comprising: main body; A base, which is located below the main body; A lifting mechanism is located between the main body and the base, which allows the main body to move relative to the base; The lifting mechanism includes: A guide post, which connects the main body and the base; A support sleeve is installed on the main body and is sleeved on the guide post and can slide along the length direction of the guide post; A support assembly is mounted on the support sleeve and movably abuts against the guide post.

[0007] A further improvement is that the support components are arranged in multiple ways along the circumference of the support sleeve. A further improvement is as follows: the support assembly further includes a housing, a rolling element, and an elastic element. The housing is connected to the support sleeve. The rolling element and the elastic element are both disposed inside the housing. The housing is provided with a clearance opening. The two ends of the elastic element abut against the inner wall of the housing and the rolling element, respectively, so that a portion of the rolling element is exposed through the clearance opening and abuts against the guide post. A further improvement is as follows: the outer peripheral wall of the support sleeve is provided with a positioning hole that penetrates the inner peripheral wall of the support sleeve, the housing is inserted into the positioning hole, and the clearance opening is oriented toward the axis of the support sleeve. A further improvement is as follows: the outer peripheral wall of the support sleeve is provided with a positioning plane, the positioning hole is provided on the positioning plane, and the outer end wall of the end of the housing away from the axis of the support sleeve is flush with the positioning plane. A further improvement is that the rolling element is a ball bearing, and the diameter of the clearance opening is smaller than the diameter of the ball bearing. A further improvement is that the outer wall of the housing is provided with an oil injection hole, which communicates with the interior of the housing. A further improvement is as follows: the main body includes a housing, the housing is provided with a receiving part for accommodating at least a portion of the guide post, the receiving part is provided with a connecting hole on the side facing the base, and the support sleeve is inserted into the connecting hole. A further improvement is as follows: the housing is provided with a fixing screw hole that communicates with the connecting hole, and a fixing stud is threadedly connected to the inner wall of the fixing screw hole, and the fixing stud abuts against the outer peripheral wall of the support sleeve. A further improvement is as follows: the inner wall of the support sleeve is provided with a chip removal groove through the axial direction of the support sleeve, and multiple chip removal grooves are provided sequentially along the circumference of the support sleeve. Compared with the prior art, the present invention has the following beneficial effects: 1. The support assembly is movably abutted against the guide post, so that the support sleeve and the guide post are roughly separated from each other; the support assembly includes a rolling element, which rotates when the main body moves relative to the base along the length of the guide post. The rolling element can pass over the wood chips and other debris adhering to the guide post, thereby facilitating the movement of the main body and making it easier to adjust the position of the main body relative to the base.

[0008] 2. Multiple support components are arranged along the circumference of the support sleeve, which can improve the uniformity of the force on the support sleeve, reduce the risk of jamming due to the support sleeve being misaligned relative to the guide post, and improve the stability of the support sleeve sliding relative to the guide post.

[0009] 3. The elastic element ensures that the rolling element always abuts against the guide post, reducing the risk of the connection between the support sleeve and the guide post becoming loose. Simultaneously, during the installation of the support sleeve, the elastic element can undergo elastic deformation, allowing the rolling element to retract into the housing, thus facilitating the fitting of the support sleeve onto the guide post.

[0010] 4. The chip discharge groove allows sawdust, dust and other debris to pass through or be contained by the sawdust and other debris pushed by the rolling parts, thereby reducing the risk of debris accumulating in the guide post or support sleeve and obstructing the rolling parts, reducing the risk of the support sleeve getting stuck, and further facilitating the sliding of the housing relative to the base.

For example, terms such as "upper," "lower," "front," and "rear" that indicate orientation or positional relationship are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0017] Reference Figure 1 and Figure 2 One embodiment of this utility model provides a bakelite milling machine 100, which includes a main body, a base 12, and a lifting mechanism 13. The housing 11 forms the main frame of the main body; the base 12 is located below the housing 11; the lifting mechanism 13 is located between the housing 11 and the base 12 and allows the housing 11 to move relative to the base 12.

[0018] The lifting mechanism 13 includes a guide column 131 and a support sleeve 132. The guide column 131 is connected to the housing 11 and the base 12; the support sleeve 132 is connected to the housing 11, and is sleeved on the guide column 131 and can slide along the length of the guide column 131. Exemplarily, the centerline of the housing 11 is parallel to the axis of the guide column 131. Figure 1The dashed box in the figure represents section I-I, which is parallel to and passes through the axis of guide post 131 and through the center line of housing 11.

[0019] Reference Figure 2 In some embodiments, the guide post 131 is cylindrical, with one end connected to the base 12 and the other end extending away from the base 12. For example, the end of the guide post 131 away from the base 12 extends upwards, such that the length of the guide post 131 is along the vertical direction.

[0020] In some embodiments, the housing 11 includes an outer shell 111 and a sliding seat 112, the sliding seat 112 being disposed below and connected to the outer shell 111. In some embodiments, a support sleeve 132 is connected to the sliding seat 112 so that the sliding seat 112 can drive the outer shell 111 to move along the length direction of the guide post 131. In other embodiments, the support sleeve 132 may be connected to the outer shell 111.

[0021] In some embodiments, the housing 11 has a receiving portion 113 for accommodating at least a portion of the guide post 131. The receiving portion 113 has a connecting hole 1131 on the side facing the base 12, and a support sleeve 132 is inserted into the connecting hole 1131. Exemplarily, the housing 111 has an internal receiving cavity 1111 with an open lower end. A sliding seat 112 covers the receiving cavity 1111 and together with the receiving cavity 1111 forms the receiving portion 113. The sliding seat 112 has a connecting hole 1131 that communicates with the receiving cavity 1111. The support sleeve 132 is inserted into the connecting hole 1131 and is interference-fitted with the connecting hole 1131. The lower end of the sliding seat 112 has a through hole 1121 that communicates with the connecting hole 1131. The guide post 131 can be inserted into the support sleeve 132 through the through hole 1121, and the upper end of the guide post 131 can be inserted into the receiving cavity 1111. In other embodiments, the receiving portion 113 may be sleeve-shaped.

[0022] Reference Figure 2 and Figure 3 In some embodiments, the sliding seat 112 is provided with a fixing screw hole 1122 communicating with the connecting hole 1131. A fixing stud 1123 is threadedly connected to the inner wall of the fixing screw hole 1122, and the fixing stud 1123 abuts against the outer peripheral wall of the support sleeve 132. It can be understood that the axial direction of the fixing screw hole 1122 intersects the axial direction of the connecting hole 1131; alternatively, the axial direction of the fixing screw hole 1122 is arranged radially along the connecting hole 1131. By rotating the fixing stud 1123, the fixing stud 1123 can be pressed tightly against the outer peripheral wall of the support sleeve 132, thereby improving the stability of the support sleeve 132 fixed to the sliding seat 112 and reducing the possibility of the support sleeve 132 detaching from the sliding seat 112.

[0023] In some embodiments, the sliding seat 112 is provided with an operating handle 1124, which is connected to the sliding seat 112 via a locking screw 1125. Optionally, the locking screw 1125 is threaded into a fixing screw hole 1122, and the fixing stud 1123 is the threaded portion of the locking screw 1125. In other embodiments, the fixing stud 1123 may be a structural component independent of the locking screw 1125, that is, the fixing screw hole 1122 and the threaded hole for mounting the locking screw 1125 are not the same threaded hole.

[0024] In some embodiments, the housing 11 is provided with a motor 114, the output shaft of which is connected to a mounting base 1141 for mounting a cutting tool (not shown). Exemplarily, the rotor 1142 and stator 1143 of the motor 114 are both located inside the housing 111, and both ends of the rotor 1142 are rotatably connected to the sliding seat 112 and the housing 111, respectively. It is understood that the base 12 has a clearance hole 121 extending through the guide post 131 along its axial direction, and the mounting base 1141 can be inserted into the clearance hole 121. When the sliding seat 112 slides towards the base 12, the mounting base 1141 can drive the cutting tool downwards to extend outside the clearance hole 121, so that the cutting tool contacts the wood product to be processed, thereby processing the wood product.

[0025] The lifting mechanism 13 also includes a support assembly 133, which is mounted on the support sleeve 132. In some embodiments, multiple support assemblies 133 are sequentially arranged along the circumference of the support sleeve 132. Exemplarily, multiple sets of multiple support assemblies 133 are spaced apart along the axial direction of the support sleeve 132, and all the support assemblies 133 in each set are evenly distributed sequentially along the circumference of the support sleeve 132.

[0026] Multiple support components 133 are arranged along the circumference of the support sleeve 132, which can improve the uniformity of the force on the support sleeve 132, reduce the risk of jamming due to the support sleeve 132 being tilted relative to the guide post 131, and improve the stability of the sliding of the support sleeve 132 relative to the guide post 131.

[0027] Reference Figure 3 The support assembly 133 includes a rolling element 1331, which rotatably abuts against the guide post 131. By rotatably abutting against the guide post 131, the support sleeve 132 and the guide post 131 are substantially separated from each other. When the housing 11 moves relative to the base 12 along the length of the guide post 131, the rolling element 1331 rotates, allowing it to pass over sawdust and other debris adhering to the guide post 131, thereby facilitating the movement of the housing 11 and adjusting its position relative to the base 12.

[0028] Reference Figure 3 and Figure 4 In some embodiments, the support assembly 133 further includes a housing 1332 and an elastic member 1333; the housing 1332 is connected to the support sleeve 132, and both the rolling member 1331 and the elastic member 1333 are disposed within the housing 1332; the housing 1332 is provided with a clearance opening 1332a, and both ends of the elastic member 1333 abut against the inner wall of the housing 1332 and the rolling member 1331 respectively, so that a portion of the rolling member 1331 is exposed through the clearance opening 1332a and abuts against the guide post 131. It can be understood that the clearance opening 1332a of the housing 1332 is oriented towards the axis of the support sleeve 132, so that the exposed portion of the rolling member 1331 abuts against the peripheral wall of the guide post 131. Figure 4 The dashed lines in the diagram are used to represent the periphery of the guide post 131.

[0029] For example, the housing 1332 is a sleeve with an internal central hole, and one end of the housing 1332 is open; the elastic element 1333 is a spring, and the rolling element 1331 is located at the end of the elastic element 1333 near the opening of the housing 1332.

[0030] In some embodiments, the rolling element 1331 is a ball 1331a, and the diameter of the clearance opening 1332a is smaller than the diameter of the ball 1331a. Exemplarily, after the elastic element 1333 and the ball 1331a are inserted into the housing 1332 through the opening, the opening of the housing 1332 can be reduced by pressing the outer peripheral wall of the opening towards the centerline of the housing 1332, thus forming the clearance opening 1332a. By making the diameter of the clearance opening 1332a smaller than the diameter of the ball 1331a, the risk of the ball 1331a falling out can be reduced. When the elastic element 1333 holds the ball 1331a against the inner wall of the housing 1332 located at the relief opening 1332a, a portion of the ball 1331a is exposed through the relief opening 1332a and holds against the peripheral wall of the guide post 131; when the sliding seat 112 drives the support sleeve 132 to move, the ball 1331a moves relative to the guide post 131, causing the ball 1331a to rotate, thereby facilitating the movement of the sliding seat 112.

[0031] The elastic element 1333 ensures that the rolling element 1331 always abuts against the guide post 131, reducing the risk of loosening of the connection between the support sleeve 132 and the guide post 131. Simultaneously, when installing the support sleeve 132, the elastic element 1333 can elastically deform, allowing the rolling element 1331 to retract into the housing 1332, thus facilitating the fitting of the support sleeve 132 onto the guide post 131.

[0032] In some embodiments, the outer wall of the housing 1332 is provided with an oil injection hole 1332b, which communicates with the interior of the housing 1332. Optionally, the oil injection hole 1332b is located on the end wall of the housing 1332 opposite to the relief opening 1332a. Lubricating fluid or grease can be injected into the housing 1332 through the oil injection hole 1332b to reduce the friction between the rolling element 1331 and the housing 1332, thereby facilitating the rotation of the rolling element 1331 and reducing the wear of the rolling element 1331 or the housing 1332.

[0033] In some embodiments, the elastic element 1333 may be omitted, and the housing 1332 may be provided with a groove, into which the ball 1331a may be embedded, so that the ball 1331a can rotate relative to the housing 1332 and the support sleeve 132. In some other embodiments, the housing 1332 may be omitted, and the inner wall of the support sleeve 132 may be provided with a groove for embedding the ball 1331a.

[0034] In other embodiments, the rolling element 1331 may be a structural component such as a roller or a shaft, and the rolling element 1331 may be rotatably connected to the support sleeve 132 or the housing 1332 via a pin.

[0035] Reference Figure 3 and Figure 5 In some embodiments, the outer peripheral wall of the support sleeve 132 is provided with a positioning plane 1321 and a positioning hole 1322. The positioning hole 1322 is provided on the positioning plane 1321 and passes through the inner peripheral wall of the support sleeve 132; the housing 1332 is inserted into the positioning hole 1322. Optionally, the housing 1332 and the positioning hole 1322 are interference-fitted.

[0036] In some embodiments, the outer end wall of the end of the housing 1332 away from the axis of the support sleeve 132 is flush with the positioning plane 1321. By setting the positioning plane 1321, it is convenient to open the positioning hole 1322 on the support sleeve 132; at the same time, by making the outer end wall of the housing 1332 flush with the positioning plane 1321, the installation depth of the housing 1332 in the positioning hole 1322 can be positioned by the positioning plane 1321, so as to accurately position the installation position of the rolling element 1331, thereby making the distance between each rolling element 1331 and the axis of the support sleeve 132 approximately the same, thereby making the support sleeve 132 and the guide post 131 approximately coaxial, so as to further facilitate the support sleeve 132 to drive the support seat to slide. It should be noted that "flush" here does not mean that the distance between the outer end wall of the housing 1332 and the positioning plane 1321 is zero. In fact, it is sufficient as long as the distance between the outer end wall of the housing 1332 and the positioning plane 1321 is within the range of -1mm to 1mm. Wherein, if the distance between the outer end wall of the housing 1332 and the positioning plane 1321 is greater than zero, it means that the outer end wall of the housing 1332 protrudes to the outside of the positioning hole 1322.

[0037] In some other embodiments, the positioning plane 1321 may be omitted, as long as it ensures that the installation depth of each housing 1332 within the positioning hole 1322 is the same.

[0038] Reference Figure 2 and Figure 5 In some embodiments, a chip removal groove 1323 is provided through the inner wall of the support sleeve 132 along the axial direction of the support sleeve 132, and multiple chip removal grooves 1323 are arranged sequentially along the circumference of the support sleeve 132. The chip removal groove 1323 allows sawdust, dust and other debris to pass through or accommodate sawdust and other debris pushed by the rolling element 1331, thereby reducing the risk of debris accumulating in the guide post 131 or the support sleeve 132 and obstructing the rolling element 1331, thereby reducing the risk of the support sleeve 132 getting stuck, and further facilitating the sliding of the housing 11 relative to the base 12.

[0039] In other embodiments, reference is made to Figure 2 The lifting mechanism also includes a guide shaft 134 and an elastic mechanism 135. The guide shaft 134 and the elastic mechanism 135 are disposed in the receiving portion 113. The elastic mechanism passes through the opening at the upper end of the guide post 131 into the interior of the guide post 131 and extends through the connecting hole 1131 until it is connected to the base 12. The guide shaft 135 is connected to the housing 11, particularly the outer casing 1111, and is disposed within the elastic mechanism 135 so as to be biased by the elastic mechanism 135.

[0040] Thus, when the user presses the operating handle 1124, the main body of the bakelite milling machine 100 will drive the guide shaft 134 or move along the guide shaft 134 under the bias of the elastic mechanism 135, and during this process, the support component 133 slides on the outer surface of the guide post 131.

[0041] In other embodiments, the elastic mechanism 135 is a helical spring.

[0042] In some other embodiments, a movable member may also be provided inside the housing 1332 of the support assembly 133. The movable member moves axially within the housing 1332 under the bias of the elastic member 1333. The end of the movable member connected to the elastic member 1333 may be a plane, and the end that abuts against the guide post 131 may be an arc-shaped or spherical surface.

[0043] Finally, it should be noted that the above-described embodiments are merely specific implementations of this utility model, used to illustrate the technical solution of this utility model, and not to limit it. The protection scope of this utility model is not limited thereto.
