Description

Technical Field

[0001] This utility model relates to the field of engine cylinder block core support technology, and in particular to a precise positioning core support for engine cylinder block casting. Background Technology

[0002] An engine block strut is a support device fixed to the engine block to prevent excessive vibration and shaking of the engine block during high-speed driving or severe bumps, thereby ensuring the stability and safety of the engine. An engine block strut is generally composed of one or more metal rods or steel pipes, installed on the engine block, and the cylinder block is firmly fixed to the vehicle body by connecting bolts or other connecting parts.

[0003] However, existing engine cylinder block core supports are difficult to adjust in length and angle according to multiple support mechanisms during use, which affects the practicality of the engine cylinder block core supports. Therefore, it is necessary to provide a new type of engine cylinder block casting with precise positioning to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a precise positioning mandrel for engine cylinder block casting, so as to solve the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a precise positioning core support for engine cylinder block casting, comprising: a connecting block, wherein a handle is fixedly connected to the upper surface of the connecting block, and an adjustment mechanism is installed in the middle of the four sides of the outer surface of the connecting block;

[0006] The other end of the adjustment mechanism is equipped with a swivel ball, a fixing bolt is inserted into one side of the swivel ball, and a support mechanism is hinged to the bottom of the swivel ball.

[0007] As a further description of the above technical solution: the adjustment mechanism includes a fixed sleeve fixedly connected to the middle of the four sides of the connecting block, a threaded rod installed in the middle of the fixed sleeve, a limit block fixedly connected to the bottom of the threaded rod, an adjustment ring sleeved on the top of the fixed sleeve, and limit rods fixedly connected to the left and right sides of the inner cavity of the fixed sleeve.

[0008] As a further description of the above technical solution: the surface of the threaded rod is connected with threads, the adjusting ring has a threaded groove adapted to the threads, the threaded rod and the adjusting ring form a rotating connection mechanism, and the limiting block has a movable hole adapted to the limiting rod.

[0009] As a further description of the above technical solution: the bottom of the adjusting ring is connected to an annular locking block, and the fixed sleeve has an annular locking groove adapted to the annular locking block. The adjusting ring and the fixed sleeve form a movable locking connection mechanism.

[0010] As a further description of the above technical solution: the support mechanism includes a support seat hinged to a universal ball, a cushioning sponge pad is installed at the bottom of the support seat, and a number of rubber balls are installed at equal intervals at the bottom of the support seat.

[0011] As a further description of the above technical solution: the support base has a circular groove that is adapted to the cushioning sponge pad.

[0012] As a further description of the above technical solution: the universal ball is provided with a threaded groove that is compatible with the fixing bolt.

[0013] This invention provides a precise positioning mandrel for engine cylinder block casting. It offers the following advantages:

[0014] 1. By setting up an adjustment mechanism, the length of the threaded rod can be adjusted by rotating the adjustment ring, which in turn adjusts the clamping sleeve on the connecting plate. This allows for individual adjustment of multiple support mechanisms during use, improving the practicality of the device. The inclusion of a universal ball and fixing bolts facilitates adjustment of the support mechanism according to the support angle, ensuring the positioning accuracy of the device.

[0015] 2. By incorporating a support mechanism and a buffer sponge pad within a circular groove around the support base, when the support base is adjusted to approach the support wall, the buffer sponge pad will be the first to contact the support wall, providing a cushioning effect on its supporting force. Furthermore, as the support base fully supports the wall, the buffer sponge pad generates a compressive force through this contact, ensuring the support base is precisely positioned against the support wall. This not only avoids rigid contact wear on the support wall and support base but also extends the service life of the core support. The inclusion of rubber balls further enhances the stability and cushioning effect during support. Attached Figure Description

[0022] 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.

[0023] Example 1, Reference Figure 1 and Figure 2 This utility model discloses a precise positioning core support for engine cylinder block casting, which can solve the problem that existing engine cylinder block core supports are difficult to adjust in length and angle according to multiple support mechanisms, thus affecting the practicality of the engine cylinder block core support. It includes a connecting block 1, a handle 2 fixedly connected to the upper surface of the connecting block 1, and an adjustment mechanism 3 installed in the middle of the four sides of the outer surface of the connecting block 1.

[0024] The other end of the adjustment mechanism 3 is equipped with a universal ball 4, a fixing bolt 5 is inserted into one side of the universal ball 4, and a support mechanism 6 is hinged to the bottom of the universal ball 4.

[0025] Working principle: Connecting block 1 facilitates component installation; handle 2 facilitates gripping and use of the device; adjustment mechanism 3 allows for individual adjustment of multiple support mechanisms 6 during use, improving the practicality of the device; universal ball 4 and fixing bolt 5 allow the support mechanism 6 to be adjusted according to the support angle, ensuring the positioning accuracy of the device; support mechanism 6 and support base 601 are precisely positioned on the support wall, which not only avoids rigid contact wear on the support wall and support base 601, but also extends the service life of the core support.

[0026] Example 2, refer to Figure 2 , Figure 3 and Figure 4This embodiment solves the problem that existing engine cylinder block core supports are difficult to adjust in length and angle according to multiple support mechanisms, thus affecting the practicality of the engine cylinder block core support. This new precision-positioning core support for engine cylinder block casting also includes an adjustment mechanism 3 comprising a fixed sleeve 301 fixedly connected to the center of the four sides of the connecting block 1, a threaded rod 302 installed in the center of the fixed sleeve 301, a limit block 303 fixedly connected to the bottom of the threaded rod 302, an adjustment ring 304 sleeved on the top of the fixed sleeve 301, and limit rods 305 fixedly connected to the left and right sides of the inner cavity of the fixed sleeve 301. The surface of the threaded rod 302 is threaded, and the adjustment ring 304 has a thread that matches the thread. The groove, threaded rod 302 and adjusting ring 304 form a rotating connection mechanism. The limiting block 303 has a movable hole that matches the limiting rod 305. The bottom of the adjusting ring 304 is connected to an annular locking block. The fixing sleeve 301 has an annular locking groove that matches the annular locking block. The adjusting ring 304 and the fixing sleeve 301 form a movable locking connection mechanism. The support mechanism 6 includes a support seat 601 hinged to the universal ball 4. The bottom of the support seat 601 is equipped with a cushioning sponge pad 602. Several rubber balls 604 are equidistantly installed on the bottom of the support seat 601. The support seat 601 has an annular groove 603 that matches the cushioning sponge pad 602. The universal ball 4 has a threaded groove that matches the fixing bolt 5.

[0027] Working Principle: After the device is placed in a suitable position, rotating the adjusting ring 304 drives the threaded rod 302 to adjust its height, allowing the four sets of support mechanisms 6 to be adjusted in length independently. This facilitates support according to the engine block requirements during use. Limit blocks 303 and limit rods 305 limit the threaded rod 302, preventing the adjusting ring 304 from rotating simultaneously with the threaded rod 302, thus ensuring normal operation of the device. The inclusion of universal balls 4 and fixing bolts 5 allows the support mechanisms 6 to be adjusted according to the support angle, ensuring accurate positioning. After the support mechanisms 6 are in place, tightening the fixing bolts 5 ensures the universal balls are fully extended. Locking ball 4 ensures the stability of the device's support. A buffer sponge pad 602 is installed within the circular groove 603 around the support base 601. When the support base 601 is adjusted to approach the support wall, the buffer sponge pad 602 will first contact the support wall, providing a buffering effect on its supporting force. Simultaneously, as the support base 601 fully supports the contact, the buffer sponge pad 602 generates a compressive force through this contact, allowing the support base 601 to be precisely positioned on the support wall. This not only avoids rigid contact wear on the support wall and support base 601 but also extends the service life of the core support. The rubber ball 604 further enhances the stability and buffering effect during support.
