Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically a shaft-mounted shot blasting machine. Background Technology

[0002] Shaft-mounted shot blasting machines are commonly used surface treatment equipment in the industrial field, mainly used for rust removal, oxide scale removal, and surface strengthening of various workpieces. They are widely used in industries such as machinery manufacturing, shipbuilding, and automotive parts. Traditional shaft-mounted shot blasting machines are typically installed by suspending the main body of the equipment at a predetermined position on the production line using a fixed hoisting structure. Their working position is relatively fixed, allowing them to process only specific areas of workpieces. In existing technology, the hoisting and positioning structure of shot blasting machines mostly adopts a rigid connection design, fixed to the load-bearing structure of the factory or equipment brackets by bolts or welding to ensure the stability of the equipment during operation.

[0003] However, the above-mentioned traditional structure has significant shortcomings: on the one hand, the position adjustment of the shot blasting machine after installation is difficult. When it is necessary to process workpieces of different sizes and processing areas, it is difficult to adjust the horizontal or vertical position of the equipment through simple operation. It is often necessary to stop the machine and manually move and reassemble the hoisting parts to perform position calibration, which is time-consuming, labor-intensive and inefficient. On the other hand, the existing hoisting structure can usually only achieve the fixed installation of the equipment and cannot drive the shot blasting machine to perform linear reciprocating motion, which results in a limited processing coverage of the equipment and makes it difficult to meet the uniform treatment requirements of complex workpiece surfaces.

[0004] In view of this, a shaft-mounted shot blasting machine is designed. Utility Model Content

[0005] The purpose of this utility model is to provide a bearing-type shot blasting machine to solve the problems of existing bearing-type shot blasting machines mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shaft-mounted shot blasting machine, comprising:

[0007] A shaft-mounted shot blasting machine, wherein a connecting piece is fixedly connected to the top of the shaft-mounted shot blasting machine;

[0008] A positioning frame is inserted and connected to the lower inner side of the connector, and several sets of adjustment slots are equally spaced on one side of the positioning frame;

[0009] The first lifting frame and the second lifting frame are respectively fixedly connected to the two ends of the positioning frame, and the upper ends of the first lifting frame and the second lifting frame are provided with internal threaded fixing holes.

[0010] A locking mechanism is provided on the positioning frame;

[0011] A drive mechanism is mounted on the first lifting frame and the second lifting frame;

[0012] The locking mechanism is adapted to lock the position of the connector and the positioning frame, and the driving mechanism is adapted to drive the connector and the bearing-type shot blasting machine to move horizontally on the positioning frame.

[0013] The locking mechanism includes:

[0014] Several sets of perforations are equidistantly opened on one side of the positioning frame;

[0015] Several sets of locking rods are respectively fitted through several sets of through holes with clearance fit;

[0016] A connecting bracket is fixedly connected to several sets of the aforementioned locking rods;

[0017] Several sets of return springs are fixedly connected between the positioning frame and the connecting bracket, and the several sets of return springs are respectively sleeved on the outside of several sets of locking rods;

[0018] The end of the locking rod away from the connecting bracket passes through the perforation gap and is connected to the adjusting groove.

[0019] Preferably, the positioning frame and the connecting member have an isosceles trapezoidal structure that is compatible when viewed from the side.

[0020] Preferably, the distance between two adjacent sets of adjustment grooves is 1 / 2 of the distance between two adjacent sets of perforations.

[0021] Preferably, the drive mechanism includes:

[0022] A servo motor is installed on the side of the first lifting frame away from the second lifting frame;

[0023] The support bearing is fixedly embedded in the second lifting frame on the side closest to the first lifting frame;

[0024] One end of the transmission lead screw is fixedly connected to the motor shaft of the servo motor, and the other end is fixedly embedded in the inner ring of the support bearing;

[0025] The surface of the transmission lead screw is connected to the upper inner wall of the connector through a threaded structure.

[0026] Preferably, the locking mechanism further includes an ejector screw, which is threaded through and connected to the inner side of the connecting bracket, and the length of the ejector screw is greater than the length of the locking rod.

[0027] Preferably, the top of the connector has several sets of oil injection holes at equal intervals. The oil injection holes are frustum-shaped and are connected to the upper inner cavity of the connector.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] 1) This application designs two working modes: dynamic drive and static locking. A tool-free, rapid switching is achieved through a mechanical interlocking mechanism between the ejector screw and the locking rod. In dynamic drive mode, a servo motor drives the transmission screw to rotate, which, in conjunction with the ejector screw, disengages the locking rod from the adjustment slot, releasing the positioning lock and allowing the shot blasting machine to move horizontally back and forth along the positioning frame. This mode supports collaborative operation between the equipment and the workpiece transport system in automated production lines. Linear motion is achieved through the threaded transmission of the transmission screw, significantly expanding the coverage area of ​​shot blasting, especially suitable for uniform surface treatment of long, large-area workpieces, avoiding blind spots in traditional fixed-installation equipment. In static locking mode, no electric drive is required; manually pulling the connecting bracket embeds the locking rod into the adjustment slot to achieve multi-level positioning locking, suitable for fine position calibration at fixed workstations, meeting the positioning requirements of small-scale, high-precision machining.

[0030] 2) This application achieves precise electronic adjustment of the shot blasting machine's working position through the cooperation of a servo motor and a transmission screw via a drive mechanism. Horizontal displacement can be completed without manual disassembly and assembly, significantly improving operational efficiency compared to traditional fixed installation methods. The locking mechanism adopts a spring preload and mechanical locking design. The return spring ensures that the locking rod is tightly embedded in the adjustment groove in the non-adjustment state, resisting equipment vibration and preventing loosening. The ejector screw facilitates quick unlocking. Combined with the isosceles trapezoidal fitting structure of the positioning frame and connecting parts, it reduces moving friction resistance while ensuring connection stability, making the equipment move smoothly and locking reliably after positioning.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] Please see Figure 1-4 This utility model provides a technical solution: a bearing-type shot blasting machine, comprising:

[0044] A shaft-mounted shot blasting machine 1 has a connecting piece 2 fixedly connected to its top.

[0045] The positioning frame 3 is inserted and connected to the lower inner side of the connector 2. Several sets of adjustment grooves 7 are equally spaced on one side of the positioning frame 3.

[0046] The first lifting frame 4 and the second lifting frame 5 are respectively fixedly connected to the two ends of the positioning frame 3. The upper ends of the first lifting frame 4 and the second lifting frame 5 are provided with internal threaded fixing holes 6.

[0047] The locking mechanism is mounted on the positioning frame 3;

[0048] The drive mechanism is mounted on the first lifting frame 4 and the second lifting frame 5;

[0049] The locking mechanism is adapted to lock the position of the connecting piece 2 and the positioning frame 3, and the driving mechanism is adapted to drive the connecting piece 2 and the shaft seat type shot blasting machine 1 to move horizontally on the positioning frame 3.

[0050] Specifically, the internal threaded fixing holes 6 of the first hoisting frame 4 and the second hoisting frame 5 provide standardized installation interfaces. The equipment can be installed in the working environment through the internal threaded fixing holes 6 and the matching screws. Combined with the guiding cooperation of the positioning frame 3 and the connecting piece 2, the convenience of equipment installation and the flexibility of position adjustment are significantly improved, solving the problems of traditional shot blasting machines being difficult to move after installation and having limited processing coverage.

[0051] Reference manual attached Figure 3 The positioning frame 3 and the connecting piece 2, when viewed from the side, form a matching isosceles trapezoidal structure. Specifically, the inclined surface of the trapezoidal surface ensures the stability of the connection between the positioning frame 3 and the connecting piece 2. At the same time, the isosceles trapezoidal structure provides a precise embedding guide for the locking rod 9 of the locking mechanism, ensuring the fitting accuracy between the locking rod 9 and the adjusting groove 7.

[0052] Reference manual attached Figure 1-3 The locking mechanism includes:

[0053] Several sets of perforations 8 are equidistantly opened on one side of the positioning frame 3;

[0054] Several sets of locking rods 9 are respectively fitted through several sets of through holes 8 with clearance fit;

[0055] Connecting bracket 10 is fixedly connected to several sets of locking rods 9;

[0056] Several sets of return springs 11 are fixedly connected between the positioning frame 3 and the connecting pull frame 10, and several sets of return springs 11 are respectively sleeved on the outside of several sets of locking rods 9;

[0057] Among them, the end of the locking rod 9 away from the connecting bracket 10 passes through the through hole 8 and is connected to the adjusting groove 7 with a clearance fit.

[0058] Specifically, the return spring 11 continuously applies a force towards the adjustment groove 7 to the connecting bracket 10, causing the locking rod 9 to be tightly embedded in the adjustment groove 7 in the non-adjusted state. This creates a dual locking effect of spring preload and mechanical locking, effectively resisting vibration and impact during shot blasting machine operation and avoiding the problem of easy loosening with traditional single bolt fastening. When position adjustment is required, pulling the connecting bracket 10 simultaneously lifts multiple sets of locking rods 9 out of the adjustment groove 7, achieving rapid unlocking, and the return spring 11 is stretched. After reaching the desired position, releasing the connecting bracket 10 causes the return spring 11 to push the locking rod 9 to automatically embed into the corresponding adjustment groove 7, completing multi-level position locking.

[0059] Reference manual attached Figure 1-2 The spacing between two adjacent sets of adjustment slots 7 is half the spacing between two adjacent sets of perforations 8. Specifically, this doubles the distribution density of the adjustment slots 7, achieving finer position adjustment accuracy compared to the traditional equidistant perforation and adjustment slot layout. For example, when the spacing between two adjacent sets of perforations 8 is 20mm, the spacing between two adjacent sets of adjustment slots 7 is 10mm, doubling the number of positioning points into which the locking rod 9 can be embedded, thus increasing the positioning accuracy to twice the original. This high-density positioning design is suitable for working conditions requiring fine position calibration, such as when performing local reinforcement treatment on small workpieces or complex curved surfaces. Millimeter-level position adjustments can be achieved by selecting different adjustment slots 7, meeting high-precision machining requirements and avoiding adjustment deviations caused by sparse positioning points.

[0060] Reference manual attached Figure 1 The drive mechanism includes:

[0061] Servo motor 12 is installed on the side of the first lifting frame 4 away from the second lifting frame 5;

[0062] The support bearing 13 is fixedly embedded in the second lifting frame 5 on the side close to the first lifting frame 4;

[0063] One end of the transmission lead screw 14 is fixedly connected to the motor shaft of the servo motor 12, and the other end is fixedly embedded in the inner ring of the support bearing 13.

[0064] The surface of the transmission screw 14 is connected to the upper inner wall of the connector 2 through a threaded structure.

[0065] Specifically, the servo motor 12 drives the transmission screw 14 to rotate, converting the rotational motion into linear motion of the connecting piece 2 through a threaded connection, allowing the shaft-mounted shot blasting machine 1 to move horizontally along the positioning frame 3. This is particularly suitable for reciprocating shot blasting of long, large-area workpieces, covering a larger processing area, avoiding blind spots in traditional fixed equipment, and improving the uniformity of surface treatment. The support bearing 13 provides stable support for the transmission screw 14, reducing radial runout during long-distance transmission. Combined with the high-precision speed control of the servo motor 12, this ensures the positional accuracy and operational stability of the shot blasting machine during dynamic movement, meeting the collaborative processing requirements of automated production lines.

[0066] Reference manual attached Figure 1-3 The locking mechanism also includes an ejector screw 15, which is threaded and connected to the inner side of the connecting bracket 10. The length of the ejector screw 15 is greater than the length of the locking rod 9. Specifically, this application designs two working modes: dynamic drive and static locking. Tool-free rapid switching is achieved through the mechanical interlocking mechanism between the ejector screw 15 and the locking rod 9. In dynamic drive mode, the servo motor 12 drives the transmission screw 14 to rotate, which, together with the ejector screw 15, disengages the locking rod 9 from the adjusting groove 7, releasing the positioning lock. This allows the shaft-mounted shot blasting machine 1 to move horizontally back and forth along the positioning frame 3. This mode supports the equipment to work collaboratively with the workpiece transfer system in an automated production line. Linear motion is achieved through the threaded transmission of the transmission screw 14, significantly expanding the coverage of shot blasting treatment. It is especially suitable for the uniform surface treatment of long, large-area workpieces, avoiding the processing blind spots of traditional fixed installation equipment. In static locking mode, no electric drive is required. The locking rod 9 can be inserted into the adjustment groove 7 by manually pulling the connecting bracket 10 to achieve multi-level positioning and locking. It is suitable for fine position calibration of fixed workstations and meets the positioning requirements of high-precision processing in a small range.

[0067] In some embodiments, a plurality of sets of oil injection holes 16 are equidistantly provided on the top of the connector 2. The oil injection holes 16 are frustoconical in shape and are connected to the upper inner cavity of the connector 2. Specifically, lubricating oil can be periodically injected through the plurality of sets of frustoconical oil injection holes 16. The frustoconical structure facilitates the concentrated flow of oil, and the lubricating oil is evenly distributed to the mating surfaces of the positioning frame 3 and the connector 2, as well as the threaded parts of the transmission screw 14 and other key friction parts by gravity and pressure, thereby reducing the wear of mechanical parts and extending the service life of the equipment. Periodic lubrication maintenance can effectively reduce transmission resistance, ensure smooth operation of the drive mechanism, reduce equipment failures caused by insufficient lubrication, and improve the durability of the overall structure. The layout design of the oil injection holes 16 takes into account both maintenance convenience and lubrication effect, allowing operators to complete maintenance without disassembling parts, significantly reducing maintenance costs and downtime in industrial production.

[0068] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
