Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a positioning seat for polishing equipment. Background Technology

[0002] Currently, most polishing devices in processing plants polish only one type of part. The difference lies in the different sizes and models of the same part. The positioning seats inside the device are mostly custom-made and installed in a designated position for adaptation. When it is necessary to process parts of different sizes, the positioning seats are adjusted. The current positioning seats are inconvenient to adjust, some of which require manual adjustment, and the flexibility of adaptation is too low. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing positioning seats, which are inconvenient to adjust, by proposing a positioning seat for polishing equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A positioning base for a polishing device includes a polishing machine body and a worktable, and further includes:

[0006] A sliding seat, which is slidably connected to the worktable via a slide rail;

[0007] Multiple sets of positioning seats, each set of positioning seats includes two positioning seats, symmetrically distributed on both sides of the top of the sliding seat, each positioning seat includes two lifting platforms and a placement seat installed on its top, the lifting platforms being vertically slidably arranged on the top of the sliding seat;

[0008] A bidirectional threaded shaft, wherein a fixed platform is fixedly provided in the middle of the top of the sliding seat, and the bidirectional threaded shaft is rotatably mounted in the fixed platform through a bearing;

[0009] The sliding platform is provided on both sides of the top of the sliding seat via slide rails. Each sliding platform is located between two lifting platforms on the same side. A push rod is fixedly provided on the top of the sliding platform via a mounting base.

[0010] The chute structure is located on the side of the lifting platform near the sliding platform, and includes an upper chute, an inclined chute, and a lower chute. The upper chute is located at both ends of the top, the lower chute is located at the center of the bottom, and the inclined chute connects the upper chute and the lower chute at an angle.

[0011] In one possible design, the placement seats in each group of positioning seats have different sizes, and the positioning seats on the same side of multiple groups of positioning seats are arranged along the length of the slide seat, with the smaller positioning seats being closer to the center of the slide seat.

[0012] In one possible design, a connecting platform is provided between adjacent positioning seat groups on the same side. The connecting platform is fixedly installed on the top of the sliding seat. A connecting groove is provided on the side of the connecting platform near the sliding table, and the end of the connecting groove is connected to the adjacent upper sliding groove.

[0013] In one possible design, the placement seat includes a mounting bracket, a placement platform fixed on top thereof, and a lateral limiting plate fixed on top thereof, the mounting bracket being bolted to the top of the lifting platform.

[0014] In one possible design, a limit rod is provided below the lifting platform, the bottom end of the limit rod is fixedly mounted on the top of the sliding seat, and the lifting platform is slidably sleeved on the outer wall of the limit rod.

[0015] In one possible design, a drive motor is fixedly mounted on the side wall of the sliding seat, and its output shaft is fixedly connected to the end of a bidirectional threaded shaft via a coupling.

[0016] In one possible design, the mounting bracket has multiple sets of bolt holes at its bottom, and the lifting platform has corresponding threaded mounting holes at its top.

[0017] In one possible design, the top of the placement platform is V-shaped.

[0018] In one possible design, double inclined guide blocks are fixedly installed on both sides of the sliding platform, inclined grooves are opened at the bottom of both sides of the lifting platform, a bottom groove for the double inclined guide blocks to move through the bottom of the connecting platform, and a fixing bolt is fixedly installed on the top of the placement platform.

[0019] In this application, during actual use, the drive motor drives the bidirectional threaded shaft to rotate, thereby causing the sliding tables on both sides to move in opposite directions. The sliding tables will drive the push rod to move through the mounting base. When the push rod enters the upper sliding groove of the lifting platform from the connecting groove, it will continue to move and abut against the side wall of the inclined sliding groove, thereby pushing the corresponding lifting platform to move upward. Until the push rod enters the interior of the lower sliding groove, the lifting platform moves to the highest point, thereby raising the placement seat above. At this time, the workpiece can be placed on the two placement tables in the same row, with both ends located within the two lateral limiting plates, to achieve positioning and installation.

[0020] In this utility model, the positioning seat for polishing equipment can be raised according to the requirements of the workpiece size by means of a height-adjustable positioning seat, thereby achieving positioning and installation, thus effectively increasing its adaptability.

[0021] In this utility model, the positioning seat for polishing equipment, through the detachable placement seat, can achieve the goal of processing and installing a suitable placement seat according to the needs at the initial and subsequent stages, and can install the placement seat at different positions on the top of the lifting platform, thereby achieving flexible adaptation.

[0022] In this invention, multiple positioning seats of different sizes and models can be installed simultaneously during use. When placing a workpiece, the matching positioning seat can be raised to achieve positioning and installation, thereby processing two workpieces simultaneously. Furthermore, when it is necessary to polish workpieces of different sizes according to the needs of different customers, the placement seat only needs to be disassembled and replaced for adaptation, achieving flexible adaptation.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] In one embodiment: Reference Figure 2-3 A positioning seat includes: a polishing machine body 1 and a worktable. A slide rail is provided on the worktable along its length. A sliding seat 2 is slidably connected to the worktable via the slide rail. A drive motor 3 is fixedly installed on the side wall of the sliding seat 2. Its output shaft is fixedly connected to the end of a bidirectional threaded shaft 7. The bidirectional threaded shaft 7 has threads with the same pitch and opposite directions at both ends of a fixed platform 4. A fixed platform 4 is centrally located on the top of the sliding seat 2 along its length. The bidirectional threaded shaft 7 is horizontally installed in the fixed platform 4 via a bearing 6. The two threaded sections of the bidirectional threaded shaft 7 are respectively threadedly connected to sliding platforms 9. The bottom of the sliding platform 9 is slidably engaged with the top of the sliding seat 2 via the slide rail.

[0033] In the above embodiment, after the drive motor 3 is powered on, it will drive the bidirectional threaded shaft 7 to rotate in the forward or reverse direction. The forward or reverse rotation of the bidirectional threaded shaft 7 will simultaneously drive the two sliding tables 9 to move closer to or further away from the fixed table 4.

[0034] Each group of positioning seats includes two positioning seats symmetrically distributed on both sides of the top of the sliding seat 2. The positioning seat includes two lifting platforms 5 and a placement seat 13 installed on its top. Each of the two positioning seats has one placement seat 13 for placing the same workpiece.

[0035] refer to Figure 4The lifting platform 5 is a rectangular metal block. A threaded hole is provided on the top of the lifting platform 5 to fix the mounting base 13. Two guide holes are provided along the height direction at the end of the lifting platform 5 away from the sliding table 9, through which the limiting rod 17 passes. A limiting head is provided at the top of the limiting rod 17 to prevent the lifting platform 5 from detaching. The limiting rod 17 is positioned to avoid contact with the mounting base 13 at the top of the lifting platform 5. The bottom end of the limiting rod 17 is vertically fixed to the top of the sliding base 2. When the lifting platform 5 is fitted onto the limiting rod 17, the guide holes and the limiting rod 17 cooperate to form a vertical sliding guide structure. A groove adapted to the push rod 10 is provided at the end of the lifting platform 5 near the sliding table 9. The groove extends inward along the length of the lifting platform 5. Two symmetrically arranged upper sliding grooves 14 are formed on both sides of the groove, allowing the push rod 10 to enter or slide out. The two upper sliding grooves 14 extend towards the lower middle part of the lifting platform 5. Two symmetrically arranged inclined slide grooves 15 are formed, which allow the push rod 10 to slide in and pass through, forming a vertical component force on the lifting platform 5. This converts the horizontal movement of the push rod 10 into the vertical movement of the lifting platform 5. When the push rod 10 slides into the inclined slide groove 15, it provides an upward force on the lifting platform 5, causing the lifting platform 5 to move upward. When the push rod 10 slides out of the inclined slide groove 15, it provides a downward force on the lifting platform 5, causing the lifting platform 5 to move downward. The lower ends of the two inclined slide grooves 15 extend horizontally towards the middle of the lifting platform 5 to form a lower slide groove 16, which provides a vertical upward support force when the push rod 10 slides in. The two upper slide grooves 14, the two inclined slide grooves 15, and the lower slide groove 16 are connected, and their cross-sectional shape is V-shaped. The upper slide grooves 14 are located at the top two ends, and the lower slide groove 16 is located at the bottom center. The inclined slide groove 15 connects the upper slide groove 14 and the lower slide groove 16 at an incline.

[0036] A push rod 10 is fixedly mounted on the top of the sliding table 9 via a mounting base 8;

[0037] In the above embodiment, when the drive motor 3 drives the bidirectional threaded shaft 7 to rotate, the two sliding platforms 9 move towards each other (synchronously moving towards the middle, or synchronously moving towards both ends). For example, when the drive motor 3 rotates in the forward direction, it drives the bidirectional threaded shaft 7 to rotate in the forward direction. At this time, the sliding platforms 9 located on both sides of the fixed platform 4 move synchronously towards the fixed platform 4. At this time, the push rod 10 moves forward (from the position of the connecting platform 12 towards the lifting platform 5 on the side closer to the fixed platform 4). The push rod 10 gradually moves from the connecting groove 11 of the connecting platform 12 to the upper sliding groove 14 in front, as the sliding platform... 9. Continuous displacement causes the push rod 10 to slide along the inclined slide 15 and push the lifting platform 5 vertically upward until it enters the lower slide 16 and stops moving. At this time, the placement seat 13 near the fixed platform 4 rises to its highest working position for placing and positioning the workpiece, while the placement seat 13 away from the fixed platform 4 remains in a low position to avoid interfering with the installation and positioning of the workpiece. After adjusting the placement seat 13, the workpiece is hoisted onto the placement seat 13 near the fixed platform 4 using a crane, so that the inclined surfaces on both sides of the workpiece are pressed against the placement seat 13, and the end of the workpiece will be in contact with the side wall of the lateral limiting plate 18. Figure 1 As shown, the upper surface of the workpiece is ground. At this time, the two ends of the workpiece are limited by the limiting plate 18, the sides and the bottom are limited by the placement seat 13, and the top is limited by the grinding head, thereby realizing the positioning and installation of the workpiece.

[0038] The mounting bracket 20 of the placement seat 13 has multiple sets of bolt holes at its bottom, which are arranged along the width of the mounting bracket 20. The top of the lifting platform 5 has corresponding threaded mounting holes. The operator can further select the appropriate threaded mounting holes according to the length of the workpiece (the length of the workpiece can be measured with a measuring ruler). The mounting bracket 20 is fixed to the designated holes on the top of the lifting platform 5 with bolts, so as to realize the position adjustment of the placement platform 19 and the side limiting plate 18 in the bidirectional threaded shaft 7 in the length direction to adapt to several commonly used workpiece lengths, thereby achieving the effect of fine adjustment. When it is necessary to adapt to a new size, the placement seat 13 can be reinstalled into the new threaded mounting holes or a new placement seat 13 of a different size can be installed.

[0039] The top shape of the placement platform 19 can be varied according to the workpiece requirements, such as V-shaped, U-shaped or flat, to enhance the workpiece support stability.

[0040] This application can be used in the field of machining, or in other fields applicable to this application.

[0041] In another embodiment: Reference Figure 1A positioning seat for a polishing equipment is used for polishing workpieces made of lightweight materials. It is applied in the field of machining. Multiple positioning seat groups are arranged sequentially along the length of the sliding seat 2. The positioning seats located on the same side of the fixed table 4 are arranged from near to far on the fixed table 4 according to the size of the workpiece from small to large. A connecting table 12 is provided between adjacent positioning seat groups. The connecting groove 11 opened on its side wall is connected to the end of the upper sliding groove 14 of the adjacent lifting table 5. When the sliding table 9 moves, the push rod 10 can enter the upper sliding groove 14 of different positioning seat groups in sequence through the connecting groove 11, so as to drive the corresponding lifting tables 5 on both sides to rise. According to the workpiece with different length and size, the lifting tables 5 of different specifications can be controlled to rise, so as to realize the graded lifting control of multiple positioning seats.

[0042] In another embodiment: Reference Figure 5 A positioning seat for a polishing device is used for polishing workpieces made of heavy materials. Double inclined guide blocks 22 are fixedly installed on both sides of the sliding table 9. Inclined grooves 21 are opened at the bottom of both sides of the lifting table 5. When the sliding table 9 moves, the double inclined guide blocks 22 abut against the inclined surfaces 21, causing the lifting table 5 to move upwards. This allows the double inclined guide blocks 22 below the lifting table 5 to act as supports when the lifting table 5 is raised to place a workpiece, thereby increasing its load-bearing capacity. A bottom groove 23 is opened at the bottom of the connecting table 12 for the movement of the double inclined guide blocks 22. A fixing bolt 24 is fixedly installed on the top of the placement table 19. When the workpiece is placed on the top of the placement table 19, the fixing bolt 24 passes through the existing through-hole on the workpiece surface and is then fixed with a nut, thereby increasing stability.

[0043] refer to Figure 6 The position of the limiting rod 17 is set to avoid the double inclined guide block 22, so that the limiting rod 17 will not obstruct the movement of the double inclined guide block 22.

[0044] In actual use, the position of the push rod 10 can be adjusted by manually starting the drive motor 3 to rotate forward and reverse. When the push rod 10 moves to the corresponding position (into the sliding groove 16 of one of the lifting platforms 5), the drive motor 3 is turned off. At this time, the bidirectional threaded shaft 7 and the sliding table 9 are self-locked by the thread, and the push rod 10 and / or the double inclined guide block 22 provide upward support force to the lifting platform 5. Automatic control can also be performed by a controller. For example, a position sensor for detecting the sliding table 9 is installed on the sliding seat 2. The position sensor is electrically connected to the PLC controller, and the drive motor 3 is electrically connected to the PLC controller.

[0045] Input the position information to be adjusted to the PLC controller. For example, adjust the sliding table 9 to move to the first position. The PLC controller controls the drive motor 3 to start, thereby driving the sliding table 9 to move to the first position through the bidirectional threaded shaft 7. When the sliding table 9 moves to the first position (when it is in the lower groove 16 of one of the lifting platforms 5), the position sensor sends a position signal to the PLC controller. The PLC controls the drive motor 3 to stop. At this time, the bidirectional threaded shaft 7 and the sliding table 9 are self-locked by the thread. The push rod 10 and / or the double inclined guide block 22 provide an upward support force to the lifting platform 5.

[0046] refer to Figure 7 A bellows cover 25 is installed to protect the bidirectional threaded shaft 7. Specifically, bellows covers 25 covering the bidirectional threaded shaft 7 are installed at both ends of the fixed platform 4. Taking the front bellows cover 25 as an example, one end of the bellows cover 25 is fixedly connected to the fixed platform 4, and the other end is fixedly connected to the inside of the platform 2. The bellows cover 25 is provided with clearance openings on the side to avoid the sliding table 9, the push rod 10, and the double inclined guide block 22, so that the sliding table 9, the push rod 10, and the double inclined guide block 22 can move freely within the bellows cover 25. The bidirectional threaded shaft 7 is always within the coverage area of ​​the bellows cover 25, thereby preventing debris generated during operation from falling on the bidirectional threaded shaft 7 and causing malfunctions.

[0047] However, as is well known to those skilled in the art, the working principles and wiring methods of the polishing machine body 1 and the drive motor 3 are conventional methods or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0048] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
