Description

Technical Field

[0001] The utility model relates to the technical field of sawing machines, and more specifically, it relates to an easy chip - discharging and shock - proof pressing wheel. Background Art

[0002] When a sawing machine works, the workpiece is cut by the rotation of the saw blade. To ensure the cutting effect, vertical cutting is generally required. Since the saw blade is long and thin, it is easy to deform during operation. Therefore, a pressing wheel is needed to correct and guide the saw blade. However, many of the current pressing wheels are in hard contact with the saw blade, unable to achieve the functions of shock absorption and chip discharging, and prone to saw jamming. Content of the Utility Model

[0003] In order to overcome the above - mentioned deficiencies, the utility model provides an easy chip - discharging and shock - proof pressing wheel, which has a shock - absorption function, and is easy to discharge chips during the contact process between the pressing wheel and the saw blade, and is not prone to saw jamming.

[0004] In order to solve the above - mentioned technical problems, the utility model adopts the following technical scheme: an easy chip - discharging and shock - proof pressing wheel, which includes a pressing wheel body installed on a connecting seat. A plurality of annular chip - discharging grooves are arranged on the outer wall of the pressing wheel body. A movable shock - proof seat is arranged on the connecting seat. The pressing wheel body is rotatably installed on the shock - proof seat, and an elastic shock - proof member is installed between the shock - proof seat and the connecting seat.

[0005] The easy chip - discharging and shock - proof pressing wheel is installed on a sawing machine. During operation, the outer side wall of the pressing wheel cup contacts the side surface of the saw blade, so as to realize the pressing and guiding of the saw blade, and avoid the saw blade from deforming and affecting the cutting effect. A plurality of annular chip - discharging grooves are arranged on the outer wall of the pressing wheel body, and the chips remaining on the saw blade can be accommodated in the chip - discharging grooves, facilitating chip discharging. An elastic shock - proof member is installed between the shock - proof seat and the connecting seat, and the pressing wheel body is rotatably installed on the shock - proof seat. Therefore, the pressing wheel body has a shock - absorption effect during operation.

[0006] The easy chip - discharging and shock - proof pressing wheel of this patent application has a shock - absorption function, and is easy to discharge chips during the contact process between the pressing wheel and the saw blade, and is not prone to saw jamming.

[0007] Preferably, a push rod is threadedly connected to the connecting seat, and the end of the push rod abuts against the shock - proof seat.

[0008] The push rod can axially move during rotation. The push rod abuts against the shock - proof seat. When the push rod moves in the direction towards the shock - proof seat, the shock - proof seat moves towards the elastic shock - proof member. When the push rod moves in the reverse direction, under the action of the elastic shock - proof member, the shock - proof seat moves in the reverse direction. The position adjustment of the shock - proof seat is realized through this structure.

[0009] In another solution, a wedge block that can move is installed on the connecting seat. An inclined pushing surface is provided on the wedge block, and a guiding surface is provided on the shockproof seat. The pushing surface is in contact with the guiding surface. A pushing screw is installed on the connecting seat, and the pushing screw is threadedly connected to the wedge block. When the pushing screw rotates, it pushes the wedge block to move.

[0010] Limited by the installation space, in many cases, the connection position of the push rod on the connecting seat is restricted, and the installation of the push rod cannot be achieved. By connecting the wedge block and the pushing screw on the connecting seat, the shockproof seat can be pushed. The axial direction of the pushing screw is perpendicular to the axial direction of the push rod. This solution can solve the problem that the installation position of the push rod is restricted.

[0011] Preferably, two pressing wheel bodies are installed on the connecting seat, and a pressing gap is formed between the side walls of the two pressing wheel bodies.

[0012] The saw blade is pressed between the side walls of the two pressing wheel bodies, and the shaping and positioning effects are good.

[0013] Preferably, the pressing wheel body includes a ring seat and a chip removal ring. An installation shaft is provided on the shockproof seat. The ring seat is rotatably installed on the installation shaft. The chip removal ring is sleeved on the ring seat, and chip removal grooves are provided on the outer wall of the chip removal ring.

[0014] The ring seat is rotatably installed on the installation shaft, and the operation is stable and reliable. The chip removal grooves are provided on the chip removal ring, and the chip removal ring is sleeved on the ring seat. When the chip removal grooves are damaged, the replacement operation of the chip removal ring is convenient.

[0015] Preferably, an upper positioning ring and a lower positioning ring are detachably connected to the ring seat. The chip removal ring is clamped between the upper positioning ring and the lower positioning ring, and the outer diameter of the lower positioning ring is smaller than the outer diameter of the chip removal ring.

[0016] The chip removal ring is positioned between the upper positioning ring and the lower positioning ring. Different thicknesses of chip removal rings, upper positioning rings and lower positioning rings are replaced according to the different widths of the saw blade to adapt to the saw blade, which is flexible and convenient. The outer diameter of the lower positioning ring is smaller than the outer diameter of the chip removal ring. Therefore, a receiving space is formed around the lower positioning ring, and the saw teeth at the lower edge of the saw blade are placed in the receiving space to prevent the saw teeth from scratching the outer wall of the pressing wheel body.

[0017] Preferably, a fastening ring is tightly connected to the lower end of the ring seat, and a limiting convex ring is provided on the upper part of the ring seat. The fastening ring abuts against the lower positioning ring, and the upper positioning ring abuts against the limiting convex ring.

[0018] The chip removal ring, the upper positioning ring and the lower positioning ring are limited between the fastening ring and the limiting convex ring, and the connection is stable and reliable.

[0019] Preferably, a positioning convex ring is provided at a position close to the upper part on the outer wall of the pressing wheel body, and a pressing surface is formed on the lower end surface of the positioning convex ring.

[0020] The positioning convex ring can position the upper edge of the saw blade. During the cutting process, the upper edge of the saw blade abuts against the pressing surface, making the shaping and positioning of the saw blade more accurate and reliable.

[0021] Preferably, a plurality of chip-through grooves are provided below the chip evacuation grooves on the outer wall of the pressing wheel body.

[0022] The chip-through grooves facilitate the downward discharge of the chips contained in the chip evacuation grooves, preventing excessive chips in the chip evacuation grooves from affecting the shaping and positioning effects of the saw blade.

[0023] Preferably, a ring of chip removal brushes is detachably installed below the chip evacuation grooves on the outer wall of the pressing wheel body.

[0024] During the operation of the saw blade, the chip removal brushes are in contact with the surface of the saw blade, thereby removing the chips remaining on the surface of the saw blade.

[0025] Compared with the prior art, the beneficial effects of the present utility model are as follows: (1) The chip-easy-to-discharge type shock-proof pressing wheel has a buffer and shock-absorbing function, and chips are easily discharged during the contact process between the pressing wheel and the saw blade, and the phenomenon of saw jamming is not likely to occur; (2) During the cutting process, the upper edge of the saw blade abuts against the pressing surface, making the shaping and positioning of the saw blade more accurate and reliable.
