Description

Technical Field

[0001] The utility model relates to the technical field of workpiece calibration, in particular to a pushing tooling. Background Art

[0002] In the field of mechanical manufacturing, many workpieces need to be machined with high precision to achieve more precise installation and closure between workpieces. However, during the installation of high-precision workpieces, it is inevitable that there are small misalignments between workpiece holes and holes or surfaces and surfaces during installation, which are difficult to calibrate. Therefore, it is necessary to use a pushing tooling to complete the calibration operation of the workpiece.

[0003] However, in the existing horizontal pushing tooling, generally, a cylinder with a magnetic switch is used to push the reference or the workpiece horizontally to adjust the relative position between the reference (or reference device) and the workpiece for calibrating the workpiece. However, simply using a cylinder with a magnetic switch cannot accurately obtain the moving amounts of the cylinder pushing and retracting, and cannot achieve high-precision control of the cylinder pushing. Therefore, the movement of the reference cannot be accurately controlled, and it is difficult to achieve high-precision calibration operation of the workpiece. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a pushing tooling to solve the technical problem in the prior art that the moving amounts of the cylinder pushing and retracting cannot be accurately obtained. The structure of the utility model is simple and the cost is lower.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A pushing tooling includes a bottom plate. A guide rail extending horizontally left and right is arranged at the upper end of the bottom plate. A flat plate is connected to the upper end of the guide rail, and the flat plate is slidably connected to the guide rail. A pushing cylinder for driving the flat plate to move horizontally left and right is further arranged on the bottom plate. A stop block assembly connected to the upper end of the bottom plate is further arranged at the front side or the rear side of the flat plate. The stop block assembly includes a first laser stop block and a second laser stop block distributed left and right. A laser sensor assembly is arranged between the first laser stop block and the second laser stop block. The laser sensor assembly is connected to the flat plate through a laser induction bracket.

[0007] The laser sensor assembly includes a first laser sensor and a second laser sensor. The laser emission port of the first laser sensor is aligned with the right end face of the first laser stop block. The laser emission port of the second laser sensor is aligned with the left end face of the second laser stop block.

[0008] A first fixed limit block is arranged on the right end face of the first laser stop block. A second fixed limit block is arranged on the left end face of the second laser stop block. A moving limit block is further arranged between the first fixed limit block and the second fixed limit block, and the moving limit block is fixedly connected to the laser induction bracket.

[0009] Further, the first fixed limit block is detachably connected to the first laser stop block; the second fixed limit block is detachably connected to the second laser stop block.

[0010] Further, the guide rail includes a first guide rail and a second guide rail that are parallelly distributed.

[0011] Further, the sum of the distance between the moving limit block and the first fixed limit block and the distance between the moving limit block and the second fixed limit block is equal to 0.5 mm.

[0012] Further, the pushing air cylinder is a single-rod air cylinder, and the single-rod air cylinder is fixedly connected to the upper end of the bottom plate through an air cylinder support; the front end of the piston rod of the single-rod air cylinder is connected to a fixed block, and the fixed block is fixedly connected to the upper end of the flat plate.

[0013] Compared with the prior art, the present utility model provides a pushing tooling, which has the following beneficial effects:

[0014] 1. In the present utility model, a laser sensor assembly is added. The laser sensor assembly includes a first laser sensor and a second laser sensor; the laser emission port of the first laser sensor is aligned with the right end face of the first laser stop block; the laser emission port of the second laser sensor is aligned with the left end face of the second laser stop block. Through the above structure, a two-way induction structure of the first laser sensor and the second laser sensor is realized.

[0015] Moreover, since the laser sensor assembly is connected to the flat plate through a laser induction bracket, when the flat plate moves horizontally left and right driven by the pushing air cylinder, the laser sensor assembly can be synchronously driven to move left and right, and further drive the left and right movement of the reference fixed to the upper end of the flat plate. During the movement, the left and right movement amounts of the reference can be accurately sensed by the first laser sensor and the second laser sensor. When the control system obtains the above movement amount data, the pushing and retracting amounts of the air cylinder can be more accurately controlled, and further the left and right movement of the reference can be controlled with high precision.

[0016] 2. At the same time, since the first fixed limit block is detachably connected to the first laser stop block, and the second fixed limit block is detachably connected to the second laser stop block. And the moving limit block fixedly connected to the laser induction bracket is placed between the first fixed limit block and the second fixed limit block. We can assemble the first fixed limit block and the second fixed limit block with different widths, and then control the distance between the first fixed limit block, the second fixed limit block and the moving limit block as required, so as to accurately control the moving amount range of the moving limit block that can move left and right between the first fixed limit block and the second fixed limit block, and further control the maximum moving amount of the laser sensor assembly moving left and right.

[0017] The pushing tooling in the present utility model can not only drive the reference to move left and right during the calibration process, but also obtain the moving amount of the left and right movement of the reference. BRIEF DESCRIPTION OF THE DRAWINGS

SPECIFIC EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0023] As Figure 1-2 shown, the present utility model provides a pushing tooling. The pushing tooling includes a bottom plate 17 provided with a plurality of mounting holes. The upper end of the bottom plate 17 is provided with a guide rail extending horizontally left and right. The upper end of the guide rail is connected with a flat plate 5, and the flat plate 5 is slidably connected with the guide rail. The bottom plate 17 is also provided with a pushing cylinder for driving the flat plate 5 to move horizontally left and right, and the pushing cylinder is connected with a magnetic switch. A block assembly connected to the upper end of the bottom plate 17 is further provided on the front side or the rear side of the flat plate 5. The block assembly includes a first laser block 9 and a second laser block 12 distributed left and right. A laser sensor assembly is provided between the first laser block 9 and the second laser block 12. The laser sensor assembly is connected to the flat plate 5 through a laser sensor support 16. In this embodiment, the first laser block 9 is connected to the upper end of the bottom plate 17 through a first fixed support 8, and the second laser block 12 is connected to the upper end of the bottom plate 17 through a second fixed support 13, as Figure 1 shown.

[0024] As Figure 1As shown in the figure, in this embodiment, two guide rails are provided between the flat plate 5 and the bottom plate 17, namely the first guide rail 6 and the second guide rail 7. The first guide rail 6 and the second guide rail 7 are distributed parallel to each other front and back, which can better and more stably support the flat plate 5 and improve the smoothness of the left and right movement of the flat plate 5.

[0025] At the same time, as Figure 1 shown, in this embodiment, the push cylinder is a single-rod cylinder 1 connected with a magnetic switch. The single-rod cylinder 1 is fixedly installed at the upper end of the bottom plate 17 through a cylinder support 3 and is located on the right side of the flat plate 5. The front end of the piston rod of the single-rod cylinder 1 is fixedly connected with the flat plate 5 through a fixing block 4. Driven by the single-rod cylinder 1, the flat plate 5 can be pushed forward or retracted left and right along the guide rail.

[0026] The upper end surface of the flat plate 5 is flat, and there are several mounting holes penetrating up and down on the upper end of the flat plate 5 for fixing the reference. For example, the reference can be fixed through a fixing bracket, that is, inserting the fixing bracket into the mounting hole or fixing the fixing bracket to the flat plate 5 with screws, so as to realize the fixation of the reference and the flat plate 5.

[0027] As Figure 1 shown, in this embodiment, the laser sensor assembly is located on the front side of the flat plate 5 and includes the laser sensor assembly, namely the first laser sensor 14 and the second laser sensor 15. In this embodiment, both the first laser sensor 14 and the second laser sensor 15 are fixedly connected with the platform 5 through laser sensor brackets 16. When the platform 5 moves left and right under the drive of the single-rod cylinder 1, the first laser sensor 14 and the second laser sensor 15 will also be driven to move left and right synchronously.

[0028] Moreover, the laser sensor assembly (the first laser sensor 14 and the second laser sensor 15) is located between the first laser block 9 and the second laser block 12. The laser emission port of the first laser sensor 14 is aligned with the right end face of the first laser block 9; the laser emission port of the second laser sensor 15 is aligned with the left end face of the second laser block 12. When the laser sensor assembly moves left and right, the distance between the first laser sensor 14 and the right end face of the first laser block 9 and the distance between the second laser sensor 15 and the left end face of the second laser block 12 will change.

[0029] At the same time, we can connect the first laser sensor 14, the second laser sensor 15 and the single-rod cylinder 1 to the control system. After the control system receives the data sensed by the first laser sensor 14 and the second laser sensor 15, it can accurately control the opening and stopping of the single-rod cylinder as needed to control the pushing and retracting of the single-rod cylinder 1 and adjust the moving amount of the reference on the upper end of the flat plate 5 within a high-precision range.

[0030] In this embodiment, a first fixed limit block 10 is provided on the right end face of the first laser stop block 9, and a second fixed limit block 11 is provided on the left end face of the second laser stop block 12; a moving limit block 18 is further provided between the first fixed limit block 10 and the second fixed limit block 11. The moving limit block 18 is a transverse convex block integrally connected to the front end of the flat plate 5 and is located at the lower end of the laser induction bracket 16. Of course, we can also fixedly connect the moving limit block 18 to the laser induction bracket 16.

[0031] During the movement of the flat plate 5, the moving limit block 18 will be restricted to move synchronously between the first fixed limit block 10 and the second fixed limit block 11. The first fixed limit block 10 and the second fixed limit block 11 limit the displacement of the flat plate 5 in the left and right directions.

[0032] In this embodiment, the first fixed limit block 10 is detachably connected to the first laser stop block 9, and the second fixed limit block 11 is detachably connected to the second laser stop block 12. Since the first fixed limit block 10 and the second fixed limit block 11 are detachably connected, we can assemble first fixed limit blocks 10 and second fixed limit blocks 11 with different widths, and then control the distance between the first fixed limit block 10, the second fixed limit block 11 and the moving limit block as needed, so as to accurately control the moving range of the moving limit block that can move left and right between the first fixed limit block and the second fixed limit block, and further control the maximum moving amount of the laser sensor assembly moving left and right.

[0033] In this embodiment, the distance between the moving limit block 18 and the first fixed limit block 10 plus the distance between the moving limit block and the second fixed limit block 11 is equal to 0.5 mm. That is to say, during the pushing and retracting process of the single-rod cylinder 1, there is a limit of 0.5 mm. Within 0.5 mm, the first laser sensor 14 and the second laser sensor 15 perform two-way precise sensing, so that the single-rod cylinder 1 can perform high-precision pushing and retracting movements within 0.5 mm.

[0034] During operation, according to different workpieces, different benchmarks can be fixedly installed on the upper end of the flat plate 5. The workpiece can be fixed on the rear side of the flat plate 5, that is, the laser sensor assembly and the workpiece are distributed on the symmetrical sides of the flat plate 5. Through the opposite and precise sensing of the first laser sensor 14 and the second laser sensor 15, high-precision sensing can be performed within an error of 0.5 mm. Under the push of the single-rod cylinder 1, the first guide rail 6 and the second guide rail 7 assist the flat plate 5 to drive the benchmark installed on the flat plate 5 to perform high-precision calibration on the workpiece.
