[0023] The utility model discloses a workpiece positioning and cutting device for solving the technical problems in the existing manual cutting processing method that the block cutting position is greatly affected by human factors, deviations are prone to occur for batch workpieces, the workpiece quality cannot be unified and the efficiency is low.

[0024] See also Figure 1-3 A workpiece positioning and cutting device provided in an embodiment of the utility model comprises a box body 1 arranged on a saw blade platform, a plurality of pressure block structures 3 and at least two limit blocks 2; the box body 1 comprises a front plate 12, a rear plate 13 and two side plates 14 fixed on a bottom plate 11, and the front plate 12 and the bottom plate 11 are respectively provided with a first gap; the limit block 2 is fixedly arranged between the rear plate 13 and the bottom plate 11, and the first gap between the two limit blocks 2 allows the saw blade 6 on the saw blade platform to pass through; each of the pressure block structures 3 passes through the front plate 12 and the side plates 14 respectively, and limits the workpiece 8 placed on the bottom plate 11 and close to the limit block 2, and when the box body 1 is pushed, the workpiece 8 is driven to move to the position of the saw blade 6 along the first gap for cutting.

[0025] In this embodiment, a workpiece positioning and cutting device is provided. After the pressing block structure 3 and the stop block 2 are arranged on the box body 1, the box body 1 is placed on the saw blade platform to push and cut the workpiece 8. The pressing block structure 3 and the stop block 2 are used together to accurately limit the size of the position of the workpiece 8 in the box body 1, so as to meet the rapid processing and cutting of workpieces 8 of different sizes. At the same time, the stop block 2 and the pressing block structure 3 will not be easily changed by human factors, which effectively ensures the uniform quality of batch workpieces 8 during processing.

[0026] The saw blade platform can be a working platform provided with a vertical saw blade. According to different processing requirements, the platform can be provided with different types of saw blades such as a vertical band saw or a table saw. The saw blade can pass through the first gap and the second gap in the box body 1 without contacting other structures. When the platform is turned on, the box body 1 is pushed so that the workpiece 8 limited in the box body 1 is close to the saw blade, and the workpiece 8 is cut by the saw blade to complete the processing of the workpiece 8.

[0027] The workpiece 8 may be a block of regular shape, such as a brick, which is not limited in the embodiment of the present invention.

[0028] Specifically, the box body 1 may include a bottom plate 11, a front plate 12, a rear plate 13 and at least two side plates 14. The front plate 12, the rear plate 13 and the side plates 14 are fixed on the floor. The front plate 12 and the rear plate 13 are respectively connected to the two side plates 14, so as to form an inner cavity for accommodating the limit block 2, the workpiece 8 and part of the pressure block structure 3. At the same time, a first gap is provided on the bottom plate 11 and the front plate 12 so that the saw blade 6 can cut the workpiece 8 along the first gap. The length of the first gap is at least greater than the length of the workpiece 8, and the width needs to meet the movement requirements of the saw blade 6. The limit block 2 can be installed between the rear plate 13 and the bottom plate 11 by screws or other buckles. The saw blade 6 is located in the first gap between the two limit blocks 2 when not started to avoid accidental damage to the workpiece 8 by the saw blade 6. Each of the pressure block structures 3 is respectively arranged through the front plate 12 and the side plate 14, and the part thereof on the outside of the box body 1 is the pressure block knob part. The pressure block on the inside can be pushed or retracted by rotating the pressure block knob, so as to adjust the limit amplitude of the workpiece 8. When using the present device, the box body 1 is opened, and the workpiece 8 is placed on the bottom plate 11 and close to the limit block 2, while at least partially spanning the first gap, and the limit amplitude is adjusted and fixed according to the required size by each of the pressure block structures 3. When the pressure block structure 3 is limited and fixed, the box body 1 is closed and the saw blade 6 is turned on, and the box body 1 is pushed so that the workpiece 8 fixed therein moves toward the saw blade 6, and the saw blade 6 starts to cut the workpiece 8 along the first gap. After the workpiece 8 is cut, the box body 1 can be opened to take out the cut workpiece 8, and the one-time processing of the workpiece 8 is completed.

[0029] It should be noted that, in order to further improve the convenience of use, the box body 1 in the present invention can be made of materials such as polypropylene or polyvinyl chloride, so as to minimize the overall weight of the device while ensuring the overall strength.

[0030] In an example of the present invention, the box body 1 further comprises a sliding cover 5 with a second gap, wherein the second gap allows the saw blade 6 to pass through; the sliding cover 5 is slidably connected to a slide groove disposed at the upper end of the side panel 14 .

[0031] In order to prevent the debris from splashing during the cutting process of the workpiece 8, the box body 1 can also be provided with a push-pull cover 5 with a second gap, and the second gap of the push-pull cover 5 is connected to the first gap on the front plate 12 to provide a position for the saw blade 6 to pass through. At the same time, in order to facilitate the opening and closing of the box body 1, a slide groove can be provided at the top of the side plate 14, and the push-pull cover 5 is provided with a sliding member matching the slide groove, and the sliding member is connected to the slide groove by sliding. When in use, the user can open the box body 1 by pulling the push-pull cover 5, and push the push-pull cover 5 after putting the workpiece 8 in, and close the cover to prevent the debris from the workpiece 8 from splashing, thereby further ensuring the user's safety.

[0032] The push-pull upper cover 5 can be divided into two upper covers that can be operated independently by the second gap to improve the flexibility of use. Alternatively, a connector is provided in the second gap to connect the two upper covers so that the user can directly perform the push-pull operation.

[0033] In addition, in order to improve the convenience of using the device and facilitate users to view the processing or limit adjustment of the workpiece 8 in real time, the push-pull upper cover 5 can be made of transparent polyvinyl chloride material.

[0034] Optionally, in order to further facilitate the user's pushing and pulling action of the push-pull upper cover 5 , a push-pull handle 51 is provided on the push-pull upper cover 5 .

[0035] In an example of the present invention, at least two of the pressing block structures 3 are arranged in parallel on both sides of the first gap of the front plate 12 ; at least two of the pressing block structures 3 are arranged perpendicular to the bottom plate 11 on the side plate 14 .

[0036] In this embodiment, in order to prevent the block structure 3 from being damaged by the saw blade 6 and to avoid deviation of the left and right limit of the workpiece 8 caused by a single block structure 3, the block structure 3 arranged on the front plate 12 can be arranged on both sides of the first gap. At the same time, the block structure 3 on the side plate 14 can be arranged at different heights perpendicular to the bottom plate 11 to adjust the limit of different positions of the workpiece 8 from the vertical direction.

[0037] Furthermore, in order to further improve the processing adaptability of the workpiece 8, a plurality of holes of different heights can be opened in pairs on both sides of the first gap of the front plate 12, and the pressure block structure 3 can be inserted into different holes to adapt to the processing of workpieces 8 of different sizes. The same holes can also be opened on the side plate 14.

[0038] In one example of the present invention, the pressure block structure 3 includes a limit knob 31, a connecting rod 32 and a limit pressure block 33 connected in sequence; the limit knob 31 is located on the outside of the side plate 14 or the front plate 12, and is used to drive the limit pressure block 33 forward or backward by rotation; the limit pressure block 33 is located inside the box body 1, and is used to contact with the workpiece 8 for limiting.

[0039] The pressure block structure 3 may include a limit knob 31, a connecting rod 32 and a limit pressure block 33. The limit pressure block 33 contacts the workpiece 8 to adjust the position of the workpiece 8. At the same time, the phase pressure block is fixedly connected with a connecting rod 32, which passes through the side plate 14 or the front plate 12 to connect with the outer limit knob 31. When in use, by rotating the limit knob 31, the connecting rod 32 converts the rotational motion of the limit knob 31 into the forward and backward motion of the limit pressure block 33, thereby driving the limit pressure block 33 to limit with different amplitudes to adapt to the cutting of the workpiece 8 in the horizontal or longitudinal state.

[0040] Among them, taking a workpiece with a square size of 230cm in height, 65cm in width and 114cm in length as an example, the workpiece cutting in the horizontal state is as follows: Figure 2 As shown, the front side of the workpiece (i.e., the length is 114 cm and the height is 230 cm) is cut, and the workpiece in the longitudinal state is cut as shown in FIG. Figure 3 As shown, the side of the workpiece (width 65cm, height 230cm) is cut.

[0041] In addition, the limit knob 31 can be rotated manually, and the edge of the limit knob 31 can be set with different rotation values, so that the user can compare the limit range to prevent the limit deviation. At the same time, the phase knob can also be rotated by PLC drive to calculate the left and right and front limit ranges according to the different sizes of the workpiece 8 required by the user, and automatically adjust each phase knob to put the workpiece 8 in the best limit position.

[0042] Optionally, a fixing member 34 for fixing the position of the connecting rod 32 is further provided on the inner side of the side plate 14 .

[0043] Since the side panels 14 and the front panel 12 can usually be made of materials with high strength and low weight, and their thickness may be relatively thin, during the use of the device, the connection between the connecting rod 32 and the side panels 14 or the front panel 12 may not be fixed due to the continuous use of the limiting structure. For this reason, a fixing member 34 for fixing the position of the connecting rod 32 may be provided on the inner side of the side panel 14 or the front panel 12. The fixing member 34 is provided with a through hole adapted to the connecting rod 32 and is fixed to the side panel 14 or the front panel 12. When the connecting rod 32 passes through the fixing member 34, the fixing member 34 can increase the supporting effect on the connecting rod 32 to prevent it from being offset due to continuous limiting.

[0044] Optionally, the connecting rod 32 is a screw rod.

[0045] The screw refers to a mechanism that converts rotary motion into linear motion, such as a ball screw, which converts the rotation of the limit knob 31 into linear motion of the limit pressure block 33 to limit the workpiece 8.

[0046] Optionally, a rotating handle 35 is further provided on the pressing block knob.

[0047] In order to facilitate the user to perform the limiting operation on the workpiece 8, a rotating handle 35 may be provided on the pressing block knob, and the limiting amplitude of the limiting pressing block 33 may correspond to the number of rotations of the rotating handle 35.

[0048] In an example of the present invention, a pair of push-pull handles 71 are further provided on the outer side of the side panel 14 for pushing and pulling the box body 1 along the direction of the first gap.

[0049] To facilitate the overall pushing and pulling of the box body 1, a push-pull handle 71 can be provided on the outer side of the two side panels 14. After the user completes the limiting operation on the workpiece 8, the push-pull handle 71 can be used to push the box body 1 in the direction of the first gap, so that the box body 1 is close to the saw blade 6 to cut the workpiece 8. After the cutting of the workpiece 8 is completed, the box body 1 is pulled by the push-pull handle 71 to reset the box body 1.

[0050] It should be noted that the positions of the push-pull handle 71 , the rotating handle 35 , etc. in this embodiment are all set within a reasonable range to meet the requirements of ergonomics and ensure the safety of personnel during the processing of the workpiece 8 .

[0051] In an example of the present invention, at least one sliding block 72 is further installed at the bottom end of the side plate 14; the sliding block 72 can be slidably connected to a slide rail provided on the saw blade platform.

[0052] In this embodiment, in order to improve the degree of automation in the processing of the workpiece 8 and further improve the processing efficiency, sliders 72 can be installed at the bottom ends of the side panels 14 on both sides. The sliders 72 are slidably connected to the slide rails set on the saw blade platform, and the sliders 72 are driven by a power unit such as a cylinder, thereby driving the box body 1 as a whole to move forward or reset, thereby cutting the workpiece 8.

[0053] In an embodiment of the utility model, a workpiece positioning and cutting device is provided, comprising a box body arranged on a saw blade platform, a plurality of pressure block structures and at least two limit blocks; the box body comprises a front plate, a rear plate and two side plates fixed on a bottom plate, and the front plate and the bottom plate are respectively provided with a first gap; a limit block is fixedly arranged between the rear plate and the bottom plate, and the first gap between the two limit blocks allows the saw blade on the saw blade platform to pass through; each pressure block structure passes through the front plate and the side plate respectively, and limits the workpiece placed on the bottom plate and close to the limit block, and when the box body is pushed, the workpiece is driven to move to the position of the saw blade along the first gap for cutting. Thus, by using the limit block and the pressure block structure in combination, the workpiece can be conveniently and quickly positioned and fixed, and the workpiece cutting efficiency is effectively improved.
